->''"You ran outta ink too, didn't you, you bastards?"''
-->-- '''Creator/SpikeSpencer''', complaining in an EasterEgg at [[GainaxEnding the conclusion]] of ''Anime/NeonGenesisEvangelion''

The special feeling that you get when you've watched a show and realized that an unusually large number of loose ends have been left dangling.

This special feeling is usually preceded by a glance at the clock, [[SpoiledByTheFormat noting that it is 9:54]], and saying, "Wow, they sure have a lot of loose ends to wrap up [[CosmicDeadline in the next six minutes]]. I wonder how they pull it off?" The answer: they don't.

Some shows, such as ''Series/TheXFiles'', actually used the principle of Left Hanging order to build an aura of mystique and uncertainty around the show. When shows that are more grounded in reality, such as ''Series/{{CSI}}'', wander into this territory, the results are rarely pretty.

Occasionally the loose ends are picked up on ''much'' later, either as part of a LampshadeHanging or as an "untold story" in the ExpandedUniverse. If, on the other hand, they're picked up later in a serious way, they might fit one of [[ThisIndexWillBeImportantLater Chekhov's tropes]]; if the entire episode is redeemed by one of more of these, it qualifies as an InnocuouslyImportantEpisode. Could also be a great opportunity for a BrickJoke.

See also NoEnding. If the hanging thread is trivial to the plot, it's WhatHappenedToTheMouse. Let the KudzuPlot grow out of hand, and you have TheChrisCarterEffect. If it was going to be explained, but the intended story was canceled, it's an AbortedArc.

It should be noted that a few of these examples are merely early plot lines that are abandoned once the main plot is kicked off. Why bother tying up loose ends on one matter when they have TheEndOfTheWorldAsWeKnowIt to deal with?

Sometimes the result of being ScrewedByTheNetwork. This ''will'' lead to CanonFodder and, thus, FanficFuel. See also CutShort where the series doesn't even get a chance to ignore their loose ends and ends abruptly.

Compare CliffHanger and BolivianArmyEnding, when deliberately used as an artistic device. Frequently this is an AdaptationInducedPlotHole, particularly as the result of sudden GeckoEnding that fails to resolve all lingering plot threads. It may also be the result of a GainaxEnding.



[[folder:Anime and Manga]]
* Chapter 44 of ''Manga/AttackOnTitan'' offers a flashback of Annie and Mikasa about to square off in a training fight, causing all the others to flock around them in excitement over who the winner will be. We're never told however, as that's where the flashback ends. WordOfGod later confirmed they had been so equally matched the instructor had to interfere and call it a draw.
* ''LightNovel/{{Baccano}}'' wraps up everything which concerns episodes 2 to 16, but the very first episode is a mash up of future events in the show, where there's a particular short scene where a blond girl slices Issac's ear off with a spear. The girl's name, Adele, is not even mentioned through the show as she would later appear in a future arc from the source material right after where the anime ends. The loose ends are lampshaded in the [=OVAs=], where [[LeaningOnTheFourthWall Carol asks Gustav why the story doesn't have a proper ending]]. Gustav's answer [[SoapWheel is that life always throws in another plot thread for everyone it ties up, meaning that there's going to be loose threads no matter where you stop, and now's just a good place as any to end things]]. Carol, on the other hand, thinks it's just a SequelHook.
* The anime of ''Manga/{{Berserk}}'' covers the Golden Age arc... and then it ends during the Eclipse. Since the series begins with a scene set ''after'' the Golden Age arc, it means ''the series never got out of the flashback''.
* ''Anime/TheBigO''. Everything is left hanging. Everything. Maybe it's the [[Anime/SerialExperimentsLain author's love of]] MindScrew, maybe it's the lack of a followup season (Creator/AdultSwim declined to produce another season). No matter what, a lot is left hanging.
* ''Manga/{{Bleach}}'': The manga was cancelled midway through its Final Arc as a result of Kubo's increasingly worsening health since 2010 that leaves him bedridden with increasing frequency; he only kept going for as long as he did as a result of an inspiring letter that he received after the death of a terminally ill child who had enjoyed reading Kubo's manga while bedridden. Many established plot threads were abandoned in order to wrap up the final battle in time for the manga's fifteenth anniversary. These include, but are not limited to, the Ishida family's true history, the reveal of several Bankai (including Ichigo new one), the fate of Captain Komamura [[spoiler:after losing his human form, the exact nature of Yachiru's existence as Kenpachi's Zanpakuto spirit (as well as the rules of Zaraki's Bankai), and whether or not Nel was able to rescue Grimmjow, Yoruichi and Urahara from Askin Nakk Le Vaar's poison prison]]. The subsequent light novels ''LightNovel/BleachWeDoKnotAlwaysLoveYou'' and ''LightNovel/BleachCannotFearYourOwnWorld'' resolve many of these.
* Mari's fate in the ''Manga/BlueDrop'' anime after [[spoiler:her loved one Hagino dies]] is never addressed, not even in the [[DistantFinale huge time skip]] at the end of the series. This is especially egregious, since [[spoiler:Hagino]] sacrificed herself to save Mari's life, so it would at least have been nice to know how Mari dealt with it.
* ''Anime/CodeGeass'' actually resolved its main premise, but several subplot threads were apparently lost in the rush or deemed less important somewhere between seasons as the staff had to alter their original plans due to an [[ExecutiveMeddling unexpected time slot change]]. They include the true nature of Suzaku's superhuman abilities, C.C.'s real name and, perhaps most frustratingly for several viewers, any sort of official explanation for the Geass.
* The anime adaptation of ''LightNovel/{{Durarara}}'' had a mostly-satisfying ending, but never addressed the fact that Izaya was still in possession of Celty's severed head. This is mostly due to the fact that the LightNovel [[OvertookTheManga series the show was based on is still running in Japan]], leaving the writers without a proper ending to adapt. With a second season currently airing, however, it's possible that this will eventually be resolved.
* ''Lightnovel/FullMetalPanic'' resolves its main plot, but leaves hanging a number of plot threads, most importantly the precise origin of The Whispered (only resolved in the novels) and the Black Technology that seems to be encoded in their genetic structure. One might presume the new season of ''Lightnovel/FullMetalPanic'', "The Second Raid", would answer some of the unresolved issues. It doesn't, and the source material is still going; while there's no absolute guarantee it'll be dealt with, resolving these issues would require [[GeckoEnding making something up just to end the anime]].
* ''Manga/{{Genshiken}}'' - both the anime and the manga, but for different reasons. In the anime, material was added for the second series to ensure enough was left for a third series, but there's no guarantee there ever will be one to finish the job. The manga has the "life goes on"-NoEnding that is so typical for SliceOfLife series, so it was almost inevitable that not everything got wrapped up.
* At the end of ''Anime/HeatGuyJ'', [[TheHero Daisuke]] has been permitted to leave Judoh and go off on adventures, and [[LoveInterest Kyoko]] tells him IWillWaitForYou (but only for three years), and he promises to come back. Off he goes, RidingIntoTheSunset and...that's it. Where did he go? What did he do? What became of Kyoko? And [[TheRival Clair]]? And the others? The world will never know. It appears to have been a SequelHook, but that sequel never materialized.
* ''Manga/KareKano'': Everything was left hanging. EVERYTHING. The play that they built up for 6 or 7 episodes never happened, there was no culture fest, and the only way to actually understand what happened between [[spoiler: Tonami and Sakura ]] in the final episode was to read the manga.
* A variety occurs in ''Manga/KoiKoi7'', where everything is set up for the final battle with the BigBad--only to have everybody inexplicably relax on a beach in the last episode. An attempt is made to explain what happened in a short [=DVD=]-only episode, but it's still one heck of a sudden turn.
* ''Manga/MahouSenseiNegima'':
** The first anime fell into this ''hard'', mainly because it was supposed to go for two seasons, but the general lack of quality and pure OffModel-ness got it killed after one season, forcing a GeckoEnding and dropping a bunch of newly introduced plot threads. Not that two seasons would have come close to covering everything in [[LongRunner the manga]], but starting a bunch of B-plots and then ending the series ''two episodes later'' is pretty bad.
** The manga hits the same issue (though much later on and [[TorchTheFranchiseAndRun for different reasons]]), trying to at least resolve as much as it can in the very last chapter and only succeeding partially. If you want to know [[spoiler:who the Gravekeeper is, what happened to Arika]] or any number of other things like that, you won't get to know. And more importantly, [[NoRomanticResolution who Negi ended with]]. In fact, we only got most likely candidates [[ShipSinking DIDN'T win]], which is even worse than not getting anything at all.
* ''Anime/MahouSensou'' introduces [[KudzuPlot a number of plot twists and potential story arcs]] throughout the second half of the show, and then ends [[GainaxEnding suddenly and]] ''[[GainaxEnding very]] [[GainaxEnding strangely]]'' without resolving any of them. Takeshi's mother using a ring that boosts her powers but drains her life force in order to train him? Never brought up again. Wizard Brace being accused of [[OldShame historical]] [[WitchHunt war crimes]]? Never brought up again. [[spoiler:Ida's sister]] ''being kidnapped by the freaking magical FBI?'' Guess what? Never brought up again! The final episode then delivered the biggest and most confusing plot twist of the whole show, and then promptly ended without explaining anything at all.
* ''Anime/MartianSuccessorNadesico'' does this ''twice'' at least in America- first, the series ends with only a bare acknowledgment of how the war ended, then they made TheMovie which takes place after a TimeSkip, doesn't explain the war's end either, and ends on its own cliffhanger (it was meant to be the first part of a movie trilogy which was never finished). The first hanger was only resolved through information which is [[AllThereInTheManual All There In The Japan-Only Sega Games]]. The last episode of the series even has the audacity to introduce ''new'' subplots just to intentionally leave them hanging.
* The ''Manga/{{Narutaru}}'' anime cuts off the second half of the story, leaving the entirety of the dragons -- where they come from, why they're here, everything -- hanging, the GovernmentConspiracy that's seemingly studying them, and the 'villains' that needlessly kill people with them and [[UtopiaJustifiesTheMeans talk of making a better world]] vanish off the face of the earth -- mind you, they were [[DesignatedVillain so badly characterized]] nobody cares much anyhow. And wraps it all up with a ShootTheShaggyDog ending.
* The original TV ending for ''Anime/NeonGenesisEvangelion'' didn't resolve much, and in fact the English edition has a hilarious Easter Egg where Spike Spencer, the English voice actor for Shinji, complained (in-character) about the sheer number of dangling plot threads that were never addressed. Many of these ended up being answered in TheMovie finale, ''End of Evangelion''.
* Parodied / {{lampshade|Hanging}}d (like a bazillion other tropes) in ''Manga/NininGaShinobuden''. Onsokumaru and another character have an ominous conversation about Shinobu's hidden destiny. In the last episode the characters realize they forgot all about this plot thread and hastily construct a MagicalGirl story to cover.
* ''Anime/PantyAndStockingWithGarterbelt'' pulls this to a seemingly sadistic degree. [[spoiler:In literally the last minute, Stocking inexplicably [[FaceHeelTurn reveals she's actually a demon]], chops Panty into pieces, and leaves Brief on a quest to gather them back up.]] The end. Aside from a tease in the episode itself, there hasn't been a whisper of a new season in the years since to follow any of this up -- which was the point, as it was a LampshadeHanging on other shows with similar conclusions. [[spoiler: ''Geekboy Homecoming'' ended up subverting this by showing the tail end of that plot thread and how Brief got Panty back, but [[ZigZaggedTrope that just opened a whole]] ''[[ZigZaggedTrope new]]'' [[ZigZaggedTrope can of worms]] by throwing in cryptic references to whatever's going on with Stocking and Garterbelt as well as the loose plot threads from [[Anime/SpacePatrolLuluco a completely unrelated series]] in ''its'' last few pages. No matter the studio, the folks behind ''[=P&S=]'' really like trolling their audience.]]
* Most of ''Anime/{{Piano}}'' is about Miu composing a piece for her piano recital. At the big moment, the story simply cuts off when Miu starts playing, without stating how the recital went or what happens between Miu and her love interest afterward. Sure, the main point is [[ComingOfAgeStory Miu's decision about her music and her life]], but it would have been nice to get some more closure.
* A particularly infamous example of this is ''Manga/RanmaOneHalf''; the anime version, already criticized for being stuffed to the brim with {{Filler}} that had absolutely no bearing on the original manga plot, concluded a full ''three years'' before the original manga did, cutting out roughly a full third of the overall plot. For those without easy access to the manga (which, as a note, did not finish officially releasing in English-speaking countries until 2006, ''ten years'' after the conclusion of the manga in the original Japanese), this was kind of a huge kick in the pants.
* ''Manga/SoulEater'' managed to end without Eibon, the enigmatic being behind Noah and the Book of Eibon having made an appearance outside of a flashback. Hell, the entirety of Noah, who has the Book of Eibon and Brew and 5 more copies of himself. Only Noah-Greed was given a major role as a villain.
* ''Manga/{{Spiral}}'' suffers this in GeckoEnding form. It's a mystery series, and its main mysteries are "What are the Blade Children?" and "What happened to Kiyotaka, Ayumu's older brother?" The anime never answers either of these questions, as the manga hadn't yet by the time it finished production. An offhand comment by Kanone might or might not imply that Kiyotaka is dead in the anime continuity, and another compares the Blade Children to cuckoos, but that's it. The manga did ultimately end up clarifying all this.
* ''LightNovel/TrinityBlood'' OvertookTheManga, and the manga seems to in turn have overtaken the LightNovels on which it was based. The [[AuthorExistenceFailure death of the original author]] didn't help matters. Bottom line is that the ending of ''Trinity Blood'' anime failed to wrap up ''any'' long-running plot threads whatsoever.
* Also see ''Anime/VariableGeo'', and how it ''doesn't'' resolve the whole deal with the tournament it's centered upon.
* Due to the GeckoEnding of the anime, ''Manga/VenusVersusVirus'' didn't end well. [[spoiler: Did Sumire and Lucia die? Though, it is greatly [[{{WMG}} suggested]] that they did survive, and that all Lucia did was [[CoolDownhug hug]] Sumire.]]
* ''Manga/TheWorldGodOnlyKnows'' has the entire plot suddenly resolved with the abrupt revelation that a main character [[spoiler:(Elsie)]] is actually a powerful monster and the enemy's ultimate weapon and her using her powers to produce some sort of CosmicRetcon that makes the good guys win somehow. A very significant number of questions are left unanswered and plot threads unresolved; in particular [[spoiler:Lune's whereabouts, what happened to Shoutarou Shiratori, and more importantly how Satyr was able to use Elsie for their plans and what will happen with the girls who still have the goddesses inside their bodies.]]

[[folder:Comic Books]]
* ''Comicbook/PaperinikNewAdventures'', full stop. Among the things left hanging:
** Issue #20, "''Mekkano''": the eponymous machine, which can break down any other machine for parts and add it to itself, is picked up in Earth Orbit by an alien spaceship, which takes it back to their base. Never seen or mentioned again.
** Issue #24, "''Twilight''": the issue's BigBad [[spoiler:is offed in a NoOneCouldSurviveThat way]], just after proclaiming that [[spoiler:with the data from his analysis of Paperinik's SwissArmyWeapon, he will proceed to TakeOverTheWorld]]. Moreover, [[spoiler:before leaving to go back to his dimension, Paperinik gives Urk a device which can transmit across dimensions, "[[SequelHook In case you need help or something comes up]]."]] Neither plot points come up again.
** Issue #25, "''Crossfire''": Paperinik meets up with what is, essentially, LaResistance within the Evron Empire. They never show up again.
** Issue #40, "''A Single Breath''": it's pretty much stated outright in the ending that [[spoiler:the issue's BigBad, a NietzscheWannabe AGodAmI with almost unlimited PsychicPowers, has survived [[NoOneCouldSurviveThat being swept away by the wave caused by the collapse of a dam]].]] Where did he end up? No one knows.
** Although it has a definite ending, ''[=PK2=]'' was severely shortened over the original plans, so the conclusion is quite hasty and leaves no certainty about the future of [[spoiler:Everett and his daughters]], although one of the last issues of PKNA can be considered a DistantFinale to both series.
** ''Might and Power'' includes ''many'' of the plot threads left hanging to continue the story, leading to ContinuityPorn.
* A storyline in ''ComicBook/PowerPack'' heavily implied that Toro, the sidekick of UsefulNotes/{{the Golden Age|OfComicBooks}} Human Torch, was not only still alive, but was also the father of Frankie Raye. This never went anywhere, and the later ''[[ComicBook/TheAvengers Avengers]][=/=][[ComicBook/TheInvaders Invaders]]'' crossover confirmed that Toro was still dead.
* ''ComicBook/NextMen'' ended with a cliffhanger in #30. Byrne had intended to conclude the story in a second series, but the collapse of the American comic book industry in the mid-1990s made it financially unfeasible for him to do so.
* When Crossgen Comics folded, they promptly ended ''every single comic'' mid-story, right when the overall plot was reaching its apex. Marvel comics said they would publish CrossGen titles, but as of yet that hasn't happened.
* Creator/DCComics' ''ComicBook/StarRaiders'' graphic novel was truncated to half its length due to a cancelled contract; many secondary characters and plot points qualify as a result.
* The final issue of ''ComicBook/CaptainAmerica and ComicBook/TheFalcon'' Vol. 2 ended with the implication that the Falcon might have been killed by Anti-Cap, as well as the real Captain America finding his abandoned costume fluttering in the wind. WordOfGod is that the {{Cliffhanger}} was meant to be a SequelHook for a solo ''Falcon'' series by [[Creator/ChristopherPriestComics Christopher Priest]], but it fell apart when Priest left the project. When the Falcon next appeared in Creator/EdBrubaker's ''Captain America'' run, he was back to wearing his costume, and there was no mention of his disappearance or the prior incident with Anti-Cap.
* Near the end of the first ''Comicbook/WarMachine'' series, Rhodey's parents claim that he has a son that he's never met. It's left ambiguous as to whether this revelation was true or simply a lie to get rid of his then-current flame, Rae, but it's never resolved one way or the other.
* ''ComicBook/{{Dinocorps}}'' ends with Jarek still alive and well, and a shot of several more Saurons still in cryogenic sleep. It's implied that Jarek had a backup evil plan, but no further issues have been published since then.
* ''{{ComicBook/Sabretooth}}'' and [[Characters/GenerationX Monet]]'s relationship in ''ComicBook/UncannyXMen2015'' due to the ''ResurrXion'' relaunch. During the run, WordOfGod mentioned that he enjoyed writing their relationship, and seemed to be [[ShipTease going]] toward [[RelationshipUpgrade more]] for the two, Also confirmed, by WordOfGod that Sabretooth would have a romance later in the series, and that the romance would not be Pyslocke. Monet eventually becomes Creed's MoralityChain, where he tries to fight reverting to his old self so he can continue to help with her M-Plate curse. The book ends with the disbanding of the team, but Sabretooth & Monet were shown to have run off together, with Psylocke comparing them to [[OutlawCouple Starkweather & Fugate]]. As of ''ResurrXion'', they are both in different books. Monet is still possessed in Strain's Generation X and Sabretooth was living in the woods before being recruited by Old Man Logan in Pak's Weapon X. No reason has been given as to why they're separated, nor has the relationship been referenced at all.
** Some inquired on Bunn's social media if he thought Greg Pak would follow up on the Creed/Monet relationship, but Bunn gave no response. Greg Pak was asked in an X-Position panel if he would continue with Bunn's work on Sabretooth -since his moral struggle & budding ship with Monet couldn't be wrapped up by the end of Uncanny. Pak said he had plans to follow up on the former, but said nothing on the latter.
* ''ComicBook/{{Runaways}}'' ended with Chase Stein getting hit by a car after chasing a girl who looked suspiciously like his dead girlfriend while the rest of the team contemplated making a deal with Chase's shady uncle. There was also some mystery about the sudden disappearance of Old Lace. When the team later reappeared in other books, Chase's near death was handwaved, and Old Lace's disappearance was explained in a way that [[VoodooShark raised more questions]], but Gert's sudden reappearance was never explained, and Chase's uncle was never heard from again. To this day, there's never been an explanation for the sudden attack that kicked off the story's events, either.
* ''ComicBook/{{Elephantmen}}'' ends with multiple subplots unresolved, the most egregious cases being that it's never revealed where [[spoiler:Serengheti took Sahara's baby, or if Raven tried to break Dr. Nikken out of prison]]. This was likely intentionally; the final page ends with Flask and Farrell going on another adventure, and the final words are "Never The End!", implying that while the comic itself has ended, [[AndTheAdventureContinues the characters will continue going on unseen adventures]].
* The newspaper strip ''ComicStrip/LittleOrphanAnnie'' ended in 2010 on a cliffhanger, as Annie was kidnapped by a war criminal called the Butcher of the Balkans, who intended to raise her like his daughter, while Daddy Warbucks was left to believe she had been killed. This cliffhanger was later unofficially resolved in the comic strip ''ComicStrip/DickTracy''.
* ComicStrip/{{Nero}}: This newspaper comic was published daily for over 55 years. Author Marc Sleen had to work so fast that he made zillions of continuity errors and plot holes that remained unsolved.
* ''ComicBook/SpiderMan'': The mystery of FACADE would have been simple to resolve in one issue, but then the ''ComicBook/TheCloneSaga'' took all the attention, until being referenced years later in ''Dark Reign Files'' and ''Amazing Spider-Man'' #678.
* The Franchise/{{Tintin}} story ''Tintin and Alph Art'' was meant to be Creator/{{Herge}}'s GrandFinale for the Tintin series, however, he was still working on a very rough draft [[AuthorExistenceFailure when he died]]. Unfortunately, he never told anyone exactly how he planned to end it, and the incomplete story ended on a colossal Cliffhanger.
* ''ComicBook/{{Wolverine}}'': Many hints at Wolverine's past have been ignored with no explanation. One was that Archangel's metallic modifications reminded Logan of the Weapon X facility, and an adamantium skull in ''Wolverine: The Jungle Adventure'' also reminds Logan, hinting that Apocalypse was involved in the Weapon X project. This was never followed up on.
* [[ComicBook/MegaMan The Archie Mega Man comic]] was cancelled due to low sales and ended right at the start of the adaptation of the fourth game. While fans of the games know how things will turn out, there was still the matter of what Mr. X [[spoiler: (who in this version is not a disguised Wily, but an aged Xander Payne who got thrown into the past following the ''[[ComicBook/SonicTheHedgehogMegaManWorldsUnite Worlds Unite]]'' crossover and had to take TheSlowPath back to the current time),]] was planning against all robot kind and how his version of the fifth game would play out.
* Due to a lawsuit with former writer Ken Penders, the [[ComicBook/ArchieComicsSonicTheHedgehog Sonic the Hedgehog comic]] was forced to pull a CosmicRetcon so that any characters of his were written out to avoid paying him royalties. As such, many storylines that were still in development such as Naugas taking over Geffory's body and still in rule over New Mobotropolis, Bunnie coping with her regained flesh, Antonie still in a coma, Scourge breaking free from the No Zone, whatever Finitivs was planning and Sally still being robot were dropped indefinitely and will no longer have an official resolution.
* ''ComicBook/TheIntimates'' was abruptly cancelled after 12 issues due to several members of its creative team moving to other, more high-profile books, and thus the series ends on a cliffhanger with the main characters running away from the Seminary.
* The mini-series, ''ComicBook/SonicMegaDrive'', was made to celebrate Sonic's 25th anniversary with a original story made in the vein of a original Sega Genesis game. They got through two issues and a third was meant to close out the series, but Archie and SEGA got into financial disagreements in 2017 which caused the book to be put into hiatus. Then ultimately cancelled when SEGA broke ties with Archie, leaving the story on a cliffhanger of Eggman having all the macguffins in his possession and Sonic and his friends setting out to find the Chaos Emeralds in order to have a chance at stopping him.

* ''[[FanFic/NewLookSeries Link's New Look]]'' was meant to be as twice as long, but only the first half was uploaded due to backlash. Later averted as the author did finish the second half.

[[folder:Films -- Animated]]
* In-universe example: In ''WesternAnimation/ToyStory2'', Woody learns his [[ShowWithinAShow TV show]] from the 1950s, ''Woody's Round-Up'', was left hanging during a cliffhanger in the final episode because low ratings caused its cancellation.
* The animated ''WesternAnimation/TheLordOfTheRings'' notoriously ended halfway through with no warning. There was supposed to a second movie to wrap things up, but it never got off the ground. ''WesternAnimation/TheReturnOfTheKing'' was produced a few years later by Rankin and Bass, the company who made the animated version of ''WesternAnimation/TheHobbit''; it did ''not'' go as well.

[[folder:Films -- Live-Action]]
* ''Film/SkyCaptainAndTheWorldOfTomorrow'': After Polly the reporter takes a photo of Joe, aka Sky Captain, he says that she left the lens cap on her camera, and her looks of joy turned into a big, big sad stare, and cut to black. Whatever happened to the falling animals, the city and their worries about the evil doctor that sent his robots, the people they rescued, and other stuff, is left to wonder. All part of the 30's serial feel of course.
* ''Film/Gamera3AwakeningOfIrys'' was given the English marketing title of ''The Incomplete Struggle'' - quite fitting, since it ends with the eponymous [[BolivianArmyEnding turtle badly wounded in the midst of a burning city with a horde of Gyaos about to descend upon him]].
* ''Film/XMenFilmSeries''
** ''Film/XMenTheLastStand'' ended with the revelations that Magneto still maintained some of his powers, and that Professor Xavier had somehow survived his death and was inhabiting a new body. The studio never followed up on either of these plot points, instead opting for [[Film/XMenFirstClass two]] [[Film/XMenOriginsWolverine prequels]] and a [[Film/TheWolverine solo spin-off starring Wolverine]] before ''finally'' following up a bit on it in ''Film/XMenDaysOfFuturePast''.
** ''Film/XMenOriginsWolverine'' ended with two {{Sequel Hook}}s in TheStinger. One revealed that SelfDemonstrating/{{Deadpool}} was still alive, and the other had an ominous scene showing Logan in Japan. The next movie, ''Film/TheWolverine'', takes place decades later and ignores both of those bits - the story takes place in Japan, but it's completely unrelated. And the Deadpool that will earn a solo movie is not that one (but is the same actor).
* ''Film/TheIncredibleHulk'':
** The film ends with a [[TheStinger post-credits]] scene where General Ross is approached by [[ComicBook/IronMan Tony Stark]], who offers to help him take down the Hulk in exchange for Ross helping out with [[Film/TheAvengers2012 a team that S.H.I.E.L.D. is putting together]]. This is never addressed in any of the subsequent Franchise/MarvelCinematicUniverse movies, and ''Film/TheConsultant'' reveals that Ross violently rejected Stark's offer.
** The movie also never reveals what happened to Samuel Sterns after he was mutated by Banner's Gamma-infected blood. This plot point was resolved in ''[[ComicBook/NickFury Fury's Big Week]]'', the official comic prequel to ''Film/{{The Avengers|2012}}''. [[spoiler:We see Sterns being confronted by Black Widow, who subsequently shoots him at the knees and brings him into S.H.I.E.L.D. custody.]]
* Another in-universe example: In ''Film/GalaxyQuest'', the last episode of the titular show when it was cancelled ended on a cliffhanger, with Captain Taggert shouting [[ChekhovsGun "Activate the Omega-13!"]].
* ''Film/FerrisBuellersDayOff'': Looks like we'll never know how Cameron's "little chat" with his father went, despite all the post-credits scenes.
* ''Film/{{W}}'' ends this way, ''literally''. At the end of the film, after he embarrasses himself by being unable to answer a reporter when she asks him what his biggest mistake was while in office, Bush has another [[ImagineSpot baseball fantasy]] where he runs to catch a long fly ball [[spoiler: which never comes down]].
* ''Film/{{Scanners}}'' ends just after Vale and Revok merge into a single being (though not in a BodyHorror sense), but there's still some ambiguity about which consciousness is more in control. GrandTheftMe of Revok by Vale would be the nicer possibility.
* ''Film/SoundOfMyVoice'': The viewer is left questioning just about everything:
** [[spoiler:Is Maggie really from the future, and is Abigail her mother? If so, why couldn't she think of a single song that was written after 2010?]]
** [[spoiler:What's wrong with Abigail? Why does she seem to have narcolepsy? Why does she always wear a hat? Why does she build strange sculptures solely from black legos? What kind of shots was her father giving her? Did she need them?]]
** [[spoiler:Was Carol really from the Justice Department? If so, why does she smuggle her files in clothing boxes? Why does she screen her hotel room for bugs? Why didn't any of the police who arrested Maggie stay around to take statements from anyone else at the scene?]]
* ''Film/TheAmazingSpiderManSeries'' was developed to be a sprawling, Marvel-style universe, many plot points that were introduced in the first two films went unresolved.
** We never do find out who Richard Parker was spying on Oscorp for, or [[spoiler:who killed Uncle Ben]], or how Gustav Fiers convinced Norman Osbourne to fund the creation of the technology for the Sinister Six in the first place.
** ''Film/TheAmazingSpiderMan2'' ends with Harry deciding to form a super villain team and forcing Spider-Man back into action. A slew of sequels [[AshcanCopy to retain the character's rights]] were planned. Then the film's diminishing returns and Sony's problems led them to [[AbortedArc abandon the idea]] and instead let Spidey into the Franchise/MarvelCinematicUniverse.
* ''Film/KingsmanTheSecretService'' ends abruptly without resolving [[spoiler:what will happen to the Kingsman order after Arthur's death]] and the general status of the world as a result of Valentine's HatePlague. All we know is that [[spoiler:Valentine is dead, Eggsy got some RescueSex, and he later returned to beat up the hooligans that were bothering him earlier in the film]].
* ''Film/ItComesAtNight'' gained notoriety for leaving just about every plot point as an AmbiguousSituation. A few examples include: [[spoiler:Where did the virus come from? Was Will lying about his family's past? What did Stanley the dog chase after, and why did he just disappear? Why were Travis and Andrew drawing pictures of ominous people in the woods? Did Andrew get infected? And what the heck does the title even refer to?]]

* ''Literature/{{Animorphs}}''
** The final book, "The Beginning", ended this way by introducing a new antagonist with absolutely no desire from the author to go further with it about 3 pages before the book and series end (she even admits to leaving the reader hanging in the afterword).
** Another incident in-series is the fate of SixthRanger David. At the end of "The Return" he begs Rachel [[MercyKill to kill him]] rather than force him to [[FateWorseThanDeath live out the rest of his days as a rat]]. Whether or not she does it is never revealed.
** The reader never finds out who burned down Joe Bob Fenestre's house. For that matter, we never find out what happened to Joe Bob Fenestre at all.
** In #41, the whole BadFuture thing turns out to be a mind exercise brought on by some other entity that is studying humans. It's not Ellimist or Crayak... So who was it?
* ''Literature/TheBrothersKaramazov'', on any number of plot points. [[spoiler:Dmitri is still wrongfully in jail, convicted of a crime he didn't commit. Ivan is still suffering from insanity. The fate of Ilyusha's family is uncertain. Alyosha's fate is uncertain.]] We've all [[AnAesop learned a lesson,]] though, so they don't need to be cleared up for us.
* ''Bonfires and Broomsticks'', the second book in ''Literature/BedknobAndBroomstick'', ends with Miss Price having gone off to the past and the children walking to the ruins of the house that she would have lived in, only to hear her disembodied voice tell them to get off of the cabbages.
* In Andrea Chang's ''The Year of the Book'' and ''Honeysuckle House'' (novels for middle-grade readers featuring Chinese-American characters), it can reasonably be said that what is more or less considered the main plot is wrapped up, but a number of important plot themes are simply left hanging, such as, in ''Honeysuckle House'', whether or not the father of the main character gets his Green Card to work in the United States. ''The Year of the Book'' at least has a sequel (May 2013), but no such luck for ''Honeysuckle House''.
* The Creator/CharlesSheffield sci-fi novel ''Cold as Ice'' follows this trope to ridiculous extremes as the writer tells the story of several, unconnected main characters. One of these, a standard [[PersonOfMassDestruction End of the World]] plot, is resolved in the main story. The others are swiftly, and without explanation, dealt with in the Epilogue.
* DiscussedTrope in ''Literature/TheDivineComedy''; the narration asks the reader to imagine if the story stopped just as a thousand Heavenly spirits from Mercury surround our heroes and begin to sing of a love unknown on Earth. The narrator hopes that making the readers think [[invoked]] "TheyWastedAPerfectlyGoodPlot" will help them understand how strongly the characters longed to talk to the ghosts of Mercury.
* Another series by Applegate that ended with the readers left hanging was ''Literature/{{Everworld}}'', which abruptly cuts off with numerous subplots, and even the main story itself, mostly unresolved. Plot threads left dangling include: [[spoiler: Brigid, the coming battles against Ka Anor, the fate of the Sennites, how the introduction of technology will affect Everworld, who will be the next mayor of Atlantis, the Great Scroll of the Gods, etc.]]
* ''Literature/HarryPotterAndTheDeathlyHallows'' leaves the fate of the evil witch Dolores Umbridge up in the air after she is placed in a high level of the government after the Death Eaters take over. J.K. Rowling soon [[WordOfGod came out and said]] that Umbridge was prosecuted and imprisoned.
* The ''LightNovel/HaruhiSuzumiya'' series of light novels has left a lot of minor, dangling plot threads unresolved that have accumulated for 11 books. Specifically, the questions of whether any character is trustworthy (to both Kyon and [[UnreliableNarrator the readers]]), what is Mikuruís true age, whether a slider will ever show up, what, if anything, is up with Tsuruya, what the initials TFEI stand for, whether Fujiwara is telling the truth when he says [[spoiler:that heís Mikuruís brother]], whether Koizumi is truly [[spoiler:the Organizationís founder and leader]], and if so, ''[[ImprobableAge how]]'', whether Mikuru is predestined to become [[FutureJerkass her future self]], and how she will remain in the SOS Brigade into Kyonís third year considering sheís a year older than the others, any future conflict between Nagato and rest of the Data Overmind, the snippets of Kyon and Haruhiís college experience that are foreshadowed at the end of the eleventh novel, and, [[ChekhovsGun perhaps most importantly]], whether Kyon will ever use his [[TrustPassword trump card]]. Though the writer said he was writing another installment, many years have passed without any hint of the twelfth novel being published, and even if it were to do so, there is no guarantee that it would resolve any of these plots.
* Johnny Truant's narrative in ''Literature/HouseOfLeaves'' ends with an anecdote he once heard about a mother who spent all of three days with a newborn child doomed to die. [[spoiler: The kid in the story could be him, meaning that he's been DeadAllAlong; Zampanò might have wrote it in as a DownerEnding (this is suggested by the one phrase in purple); none of this is explained]]. ''[[FictionalDocument The Navidson Record]]'' ends on a [[BittersweetEnding higher note]], but that's [[UnreliableNarrator little consolation]].
* ''LightNovel/MariaSamaGaMiteru'' ends before Yumi's graduation, and leaves many questions unanswered. Who will Noriko and Touko's new petite soeurs be? What will Yumi do after graduation? And, most importantly, will Yumi and Sachiko finally [[RelationshipUpgrade enter a relationship]], or [[RelationshipCeiling remain soeurs forever]]?
* Creator/PiersAnthony had a book called ''Mute'' which created an entire well-defined and intriguing universe, with complex characters and hinted-at half-revealed {{plan}}s, ended it on an unresolved plot CliffHanger... and then dropped it. WordOfGod is that he's not going to pick it up again, ever.
* Serial mystery novel ''Literature/TheMysteryOfEdwinDrood'' was Left Hanging by AuthorExistenceFailure when Creator/CharlesDickens died.
* In ''Literature/TheNeverendingStory'' many subplots are deliberately left unresolved: "But that is another story, to be told another time."
* ''Literature/RedMoonRising'' has no resolutions given with regards to [[spoiler: the full effects of Danny's Change, his relationship with Juliet, or the assassination of Huey Seele]]. And it seems unlikely that the book will receive a sequel any time soon.
* Raymond E. Feist's ''[[Literature/TheRiftwarCycle Riftwar Legacy]]'' series, which was left unfinished due to copyright issues, since two of the three books were novelisations on Riftwar-based video games. The events that presumably happen during the finale of that series have been referenced in later books, but it is uncertain whether the books will actually ever be written.
* ''Literature/ASeriesOfUnfortunateEvents'' :
** The books never officially explain what the Sugar Bowl secret is, they never explain who actually burned down the Baudelaire mansion... In fact, the series ends with a note that basically says, RealLife is full of mysteries. Get over it.
** Also, the fates of the Quagmires, Captain Widdershins and his stepchildren, and Hector.
* According to WordOfGod, ''Literature/TheWheelOfTime'' was always planned to end with a few plotlines not fully resolved, because Robert Jordan wanted the reader to be able to imagine his world and the lives of his characters continuing past the end of the final book. Probably the biggest thing left up to the reader to decide is whether [[spoiler: the BadFuture that Aviendha saw]] can be prevented.
* ''Literature/AWolfInTheSoul'' ends with Greg [[spoiler:defeating the werewolf and returning to normal]], but many other subplots, such as [[spoiler:his parents' marriage and the reason he was infected in the first place]] remain unresolved.

[[folder:Live-Action TV]]
* ''Series/SesameStreet'': A classic Ernie and Bert skit "Ernie's Short Story" -- which is the alphabet -- comically twists this. After Ernie gives his usual over-the-top performance of it (a standard opening, followed by "the sad part," "the exciting part" and "the big finish") ... he leaves viewers "hanging" by stopping after "Y" and when Bert presses Ernie for the obvious conclusion ("Z"), Ernie says, "Wha? And give away the ending?" before giving his trademark giggle and Bert frustrated.
* {{Series/Atlantis}} got cancelled after 2 seasons ending with [[spoiler: a resurrected Pasiphae taking over Atlantis]] and Jason and friends starting his quest to find the Golden Fleece.
* ''Series/TwentyFour'' has an unfortunate tendency to simply abandon important secondary characters and leave their fates hanging; examples include Rick from season 1; Miguel, and Lynne Kresge from season 2; Andrew Paige and (quite egregiously) Behrooz Araz in season 4; and former President Charles Logan in season 6. The hanging plot thread regarding Charles Logan was ultimately subverted it the long run, as he turns out to have survived his wound and went on to serve as the BigBad of the final season.
* ''Series/NowAndAgain'' - final episode of the first (and only) season ends with most of the plot strands resolved and a brand new bunch just springing out in the last five minutes.
* ''Series/StarTrekTheNextGeneration'', in the GroundhogDayLoop episode. When the loop breaks, they find out that their collision partner is a ship -- captained by Kelsey Grammer -- that is a full century out of date, the USS ''Bozeman''. It was never mentioned on the show again, but dialogue references to a ship named "Bozeman" popped up in both ''Star Trek: Generations'' and ''Star Trek: First Contact'', and it was the subject of a (non-canon) novel. ''TNG'' also left the fate of ''Enterprise-C'' and the [[BackFromtheDead alternate timeline]] Tasha Yar hanging in "Yesterday's Enterprise". Did they succeed in their mission, or die senseless deaths? All we knew is that their passing back into the phenomenon, they restored ''Enterprise-D'' to it's original timeline, with only Guinan aware of the entire affair. It wasn't until much later (several seasons) that the fate of Tasha Yar was learned.
* The 2000s ''Series/{{Battlestar Galactica|2003}}'' has a reputation for not leaving plot threads unresolved, though due to the sheer number of threads ongoing in any episode some tend to be dropped due to lack of time or neglect. Examples include Boxey in Season 1, who was left on the cutting room floor after two episodes, and "Shelly Godfrey", a Number Six hiding within the civilian fleet who is never seen again after her sole appearance. (Notably, Helo's storyline was ''intended'' to be abandoned after the pilot miniseries, but was maintained due to popular demand.) Apparently, Shelly Godfrey will eventually be explained, in "The Plan". However, the Opera House itself (not the visions), the original temple on the Algae Planet, and the exact nature of the Lords of Kobol seem destined to remain in the file marked Left Hanging. Not to mention "God". Many fans thought that Shelly Godfrey was just Head Six who had materialized herself to help Baltar, but The Plan shows that she was a real Six trying to discredit him. Cavil and another, cooler Six intimate that she made it too easy to discover her fake evidence because of Baltar's "dreamy hair".
* ''Series/{{Moesha}}'' ended with Myles having been kidnapped.
* Seems like we'll never find out now what was going on with that damn spy pen in ''Series/VeronicaMars''...
* ''Series/{{Firefly}}'s'' abrupt cancellation left a number of plot threads dangling. Though many of them, particularly River's psychosis and the origins of the Reavers, were covered in TheMovie, many more, such as Book's past, were left in the air. They're only resolved in the comics, Book in particular gets a trilogy devoted to his past.
* ''Series/StargateSG1'' ends with an episode that makes no attempt to resolve ''any'' of its plot lines. Of course, given the many times they were Absolutely Finally About to Be Canceled and got renewed again, it could be that the PowersThatBe didn't know it was for real this time. At any rate, a WrapItUp movie, ''Stargate: Film/TheArkOfTruth,'' came out and resolved the Ori plotline, and was followed up by ''Film/StargateContinuum''. A third movie was announced, but seems to be stuck in DevelopmentHell.\\\
And a canonical MMORPG, and concepts for another series... Interestingly however, ''Stargate: The Ark of Truth'' seemed to be quite deliberate in avoiding stating "Yes, the [[spoiler:Asgard are dead and gone we're not going to retcon that]]." Events from the final [=SG1=] episode remain, for instance the presence of the [[spoiler:Asgard computer core]], but there is no reference to the [[spoiler:fate of the Asgard]]. Oddly though, they are stated as an intended playable race in the MMORPG, which takes place some time after the upcoming movies -- supposedly a significant amount of time, despite, again, being allegedly canonical.\\\
Stargate is a prime example of this trope in general. Especially in the first seasons there were a lot of plotlines opened that were just left hanging. For example Daniel's grandfather as ambassador with an alien super race is never again heard from. Or the time they found a device with the recorded knowledge of all the ancient races on a planet where the gate plunges into the ocean is never visited again as soon as the SGC has ships. You should think something like this would be of value enough to fly there, especially since the planet was very close to Earth.
* Keeping with the Stargate tradition is ''Series/StargateUniverse'', At the end of the final episode [[spoiler:Eli has decided to stay awake onboard the Destiny while everyone else goes into stasis, in hopes of fixing the broken stasis pod and joining them so the Destiny can begin is ''really'' long voyage to another galaxy, one where they are not constantly pursued by evil aliens and robot drones. It end with Eli staring contemplatively into space and no follow-up seasons exist to resolve matters.]]
* ''Series/{{Sliders}}'' ends similarly, with a finale that ends on a cliffhanger, with a few but not all plot threads updated if not resolved. There was also talk of a WrapItUp movie for ''that'' one, but it [[DevelopmentHell never got beyond the talk phase]].
* ''Series/RedDwarf'' ends with a sci-fi cliffhanger involving Rimmer kicking Death in the groin with the rest of his cast members are in a mirror universe, while the ship was being eaten slowly by a genetically engineered virus.
** The new 3-parter on Dave 10 years later does nothing to resolve this, as it's set, well, 10 years later. In fact, just to make things more frustrating (intentionally), the 3-parter includes a meta-reference to the existence of a "Series 9" which included resolution of this plot (there wasn't one, the show ended at series 8 and then the next episodes were the 3-parter). Then after the 3-parter the show started "Series X". In the finale of series X they even specifically mentioned the cliff-hanger at the end of series 8 but changed the topic before they could give the audience any details about it what happened with it.
** Lampshaded/subverted with the end of Season 2. Season 2 ended with Dave pregnant with twins fathered by a female version of himself from a mirror universe. Season 3 opened with a Star Wars Crawl that explained it all away, but was too fast to read.
* The ending of the TV miniseries ''Series/TheLostRoom'' appears to totally forget about the fates of Detective Bridgewater and Dr. Ruber.
* The Fox sci-fi series ''Series/SpaceAboveAndBeyond'' ended its one season run with an awful lot of loose ends left unwrapped. The show ended with one character presumed dead, two more falling in an escape pod into enemy territory, one reunited with his prisoner-of-war lover, and everyone else generally in limbo.
* ''90210'' started off as a series that involved both the old gang ([[Series/BeverlyHills90210 the ones from the 90s]]) and a new fresh almost entirely unrelated (except for the half-sister of the franchise protagonist). For instance, it was revealed that [[spoiler: Dylan and Kelly had a son but then broke up, Brenda was sterile but ended up adopting, Kelly's mother relapsed in alcoholism and got cancer for which she'd die in the second season]], but as the show changed executives, it was decided that it wouldn't rely on the old gang any longer (except for Kelly, who's now been downgraded to recurring supporting character), leaving the whole thing about [[spoiler: what happened to Donna and David, their divorce, their kid, David's flowers and message]] in the air.
* The final (British) series of ''Series/{{Primeval}}'' ended with a battered, bloodied future version of Matt appearing him, warning him that there's still something he needs to fix, and that he needs to 'go back'. With the ''New World'' series mostly unrelated to the old characters, the movie languishing in DevelopmentHell and the sixth series even worse, it is doubtful this huge plot thread will ever be picked up.
* ''Series/{{Titus}}'' was canceled before they could write a proper episode to conclude the series. While the last episode was good and funny, it ended with [[spoiler:Titus being put in a mental hospital for a few months as a stipulation for everyone to avoid jail time.]]
* ''Series/TheOfficeUS'':
** One episode deals with Dwight finding a joint in the parking lot and becoming more paranoid than ever as he tries to find the culprit. By the end this morphs into Dwight covering for Michael, who had accidentally inhaled some pot smoke the night before, leaving the question of how the joint itself got there unanswered. It's revealed in a deleted scene that it's two employees from Vance Refrigeration.
** Dwight never finds the man who flashed Phyllis.
* ''Series/KamenRider Kabuto'': [[spoiler: Who is Dark Tendou? Why was ZECT cooperating with worms from time to time? Where did the Hopper Riders come from?]]
* In ''Series/PhilOfTheFuture'', after Phil and Keely get together, the Diffys head back to the future, only to turn around for the cavemen Curtis. Then it ends forever.
* The cliffhanger at the end of season 2 of ''Series/{{Lost}}'' did not become relevant until near the end of Season 3. It was not directly referenced and resolved till the end of the ''fourth'' season. On the plus side, you can take it as evidence disproving that [[WritingByTheSeatOfYourPants the writers are making it up as they go along]].
* Name a high-concept SitCom from TheSixties. ''Series/LostInSpace'', ''Series/GilligansIsland'', and many others were summarily canceled when the time came, even after a successful run and regardless of whether or not the show featured AnArc, simply because that's how business was done at the time. A lot of them eventually got WrapItUp movies once they'd had enough time in syndication to get interest back up.
* ''Series/TwinPeaks'':
** Perhaps David Lynch thought that by leaving ''every single subplot'' sadistically hanging on multiple cliffs that the fans would scream and cry for another season in which to see them all resolved. If such was the case, then the tactic didn't work as the show was canceled with little fanfare and with much grumping by the small devoted fanbase the show had. And apart from the subplots, the main plot wasn't really resolved with the "How's Annie!" ending either.
** Interestingly, the show was originally planning on doing this on purpose with the murder of Laura Palmer; part of the reason for the SeasonalRot (and consequent cancellation) of season 2 is that the [[ExecutiveMeddling network forced them to reveal the murderer]].
** The movie, ''Film/TwinPeaksFireWalkWithMe'', ended up a prequel, which meant it did almost nothing to resolve any of these ambiguities. However, in the usual Twin Peaks fashion, there are a few chronological irregularities that tie into the events of the series' finale (though in a very ambiguous and indirect manner).
** A sequel series, released almost 25 years after the fact, does tie up some unresolved plot and character points, though leaves others unanswered and adds quite a few new ones as well.
* In the ''Series/{{Cracker}}'' episode "One Day A Lemming Will Fly", [[spoiler: Fitz actually spends the entire episode pursuing the wrong man for the murder of a child. The episode's entire resolution hinges on the fact that the child's killer will never be known - at least, until he strikes again...]]
* ''Series/KyleXY'' left many plots dangling (although WordOfGod cleared up a few of them). In fact, the finale actually ''introduced'' [[LukeIAmYourFather a new plotline]] in the last few seconds of the episode!
* ''Series/TerminatorTheSarahConnorChronicles'' ends with John being sent into the future with a T-1001 where Kyle is the leader of the resistance and nobody has heard of John Conner. Also Sarah remains in the past, Cameron's human double is alive and John Henry the computer program, which is apparently built to help the resistance, has gone missing.
* ''Series/{{Farscape}}'' had, initially, one of the most evil Left Hanging endings ever. Knowing they were going to be canceled, the writers extricated the crew from the worst of the crap they were buried in, and set them on a planet to recuperate. This left some of the major arcs unfinished, but hey, we can deal with that, right? So there they are, recuperating. [[spoiler: John proposes to Aeryn. It's a really touching moment. The crew are watching, all happy. Then, out of nowhere, the newly affianced couple get ''blown up by a random fighter craft''.]] ToBeContinued. On a show that's canceled. Luckily, there was enough fan pressure that a TV miniseries, the Peacekeeper Wars, was eventually made and tied up the remaining loose ends.
* The ''Series/LawAndOrderSpecialVictimsUnit'' episode "Harm" was rather bad with this. The detectives find that a woman may have been raped and murdered for helping refugees. They interview the widow of a man she helped, who claims her husband was murdered as well. They eventually book a doctor-slash-TortureTechnician for the latter crime, but at her trial, one of the jurors faints, a mistrial is called, and the doctor's fate is left ambiguous. It appears to have been intended to make you "think" about liberty vs. security and all that jazz, were it not for two facts: first, the doctor is portrayed as an entirely negative character, and second, the plot of the initial murder is just dropped.
** There was also another episode that left whether 1. The "victim" was raped by her teacher/date or 2. She was crying wolf entirely ambiguous. Said episode ended abruptly displaying the results of a survey whose participants thought 1. The man was guilty, 2. He was innocent or 3. There "wasn't enough" evidence to make a judgment on the facts displayed.
** The season eleven episode "Savior" did this. A young prostitute goes into premature labor and her baby is put on life support. The mother then runs away, giving power of attorney to Olivia, effectively giving Olivia the choice of whether the baby lives or dies. The episode ends with the baby needing immediate brain surgery and the doctors hammering Olivia for a decision that she never gives. This turns into a case of WhatHappenedToTheMouse, as neither the baby nor the mother are ever seen or heard from again.
** [[ClosingCredits "Executive Producer Dick Wolf"]] are often claimed to be the most frustrating words in the English language, due to the many episodes of ''Series/LawAndOrder'', and the spin offs, that end without enough resolution or sometimes any resolution at all.
* Due to being canceled by the second season, ''Series/PushingDaisies'' left a lot of stuff hanging, in spite of its sweet finale. Alfredo and Oscar were PutOnABus by the end of the first season, and no one will ever find out where is [[spoiler: Charles Charles]] or what the deal with [[spoiler: Ned's father]] was.
* ''Series/BabylonFive'' inverts this problem--the carefully planned five-season format of the original show wrapped up ''the entire premise of the universe'' at the end of the series, dooming future sequels to serious {{Sequelitis}} from the very beginning, as they seem like nothing but barely related afterthoughts to a story that has already been told. A more straight example is the SpinOff sequel ''Crusade'', which was ScrewedByTheNetwork only half a season in, leaving the Drakh plague story arc unresolved.
** According to JMS's DVD commentary, the plague plot was to have been wrapped up in the second season. As with the original, the real plot was supposed to lead out of things that seemed like minor side details in the episodes that actually aired. The endgame for the Drakh war was handled in novels set more than a decade after the events of the full run of Crusade would have been over.
* The '90s AMC series ''Remember WENN'' ended with an unresolved cliffhanger after the network's new management abruptly canceled the show.
* The MythArc of ''Series/TheXFiles'' never received a fitting conclusion. This series has also drifted in and out of ScrewedByTheNetwork and UnCanceled ''several'' times, so Creator/ChrisCarter knows he's playing with fire.
* ''Series/TheSopranos'': Hey, what ever did happen to that [[RetiredBadass Russian guy]] in the woods?
* ''Series/{{Deadwood}}'' was canceled after three seasons, and had been intended to run longer. As the series was based on [[RealLife the real history of Deadwood]] in a macro sense, there was enough material and history left for at least a few more seasons. Due to the abrupt cancellation, several plotlines had to be hastily tied up, to no one's satisfaction.
* ''Series/{{Flash Forward|2009}}'' left just about all plotlines open due to series cancellation.
* ''Series/FoylesWar'' was canceled and restarted multiple times, with each cancellation resulting in an attempt to tie up the series hastily, and then put everyone together again when the series resumed. Furthermore, the first cancellation resulted in the season then in production to skip several months of time in RealLife per episode. Prior to that season, each episode had a gap of days or weeks.
* ''Series/{{ALF}}'' ends with the eponymous alien surrounded by government agents facing certain vivisection. What happens to him after would later be covered in a TV movie.
* ''Series/{{Bugs}}'' ended with Alex's husband murdered by persons unknown at her wedding and Beckett and Ros being kidnapped by a mysterious man they seemed to recognize. The cancellation of the series means we'll never know who killed the poor man, or who kidnapped our two heroes.
* The first season of ''Series/{{Class}}'' ended on a triple cliffhanger : Miss Quill was pregnant with a kid that could kill her, April was trapped in the body of an alien, and the Board of Governors' backers were revealed. BBC has announced that there won't be a second season, so no resolutions to those plotlines.
* ''Series/MyNameIsEarl'' was canceled at the end of the fourth season, which ended on a big cliffhanger and a To Be Continued. It's somewhat dealt with on ''Series/RaisingHope'' where we find out that a "A local man who made list of good things to do finally finished it." Both shows are by the same creator, Greg Garcia.
* According to [[http://www.platypuscomix.net/hollywood/shrunktv.html this page]], ''Series/HoneyIShrunkTheKids'' ended its first season revealing that the leader of the Men in Black (no, not ''those'' Film/MenInBlack) was an evil alien who had plans for the Szalinskis. It ended up getting [[WhatHappenedToTheMouse tossed by the wayside]] for the rest of the series.
* ''Series/ICarly'' has a few plot-points unresolved or not referred to, and they revolve around the {{shipping}} that is not the main focus for the show, and only comes up in a handful of episodes per season. There are differing ideas on what it meant, mostly around which side of the Creddie (Carly + Freddie) or Seddie (Sam + Freddie) shipping divide people stand on.
** The first, is the end of "iThink They Kissed" where Carly asks Sam and Freddie (who shared a FirstKiss, then hid it from Carly), how long it was, and if they enjoyed it. The episode ended before they answered the question.
** The second, is at the end of "iSpeed Date", Sam walks in on Freddie and Carly sharing a slow romantic dance in each other's arms. She walks out with saying a word. Again, it's not been brought up again, so speculation abounds on her motives and feelings for Freddie (or [[HoYay/ICarly Carly]]). Again, what people think is based around the shipping divide.
** Finally, "iSaved Your Life", where Freddie saves Carly's life, they enter a relationship. Carly tries to say she loves Freddie, but Freddie still breaks up with her because Sam put it into his head that Carly just loved that he was heroic and she's just hero worshiping. Freddie says to Carly that if she wants to be his boyfriend in the future, he'd love to. Neither this nor any of the mentioned plot-points have been mentioned again, and a deliberate CliffHanger which adds even more questions, in the last episode of Season 4 means it'll be at least another 3 or 4 months before any could get possibly answered.
* An episode of ''Series/WalkerTexasRanger'' had Cordell Walker rescue a girl who was trapped in a Christian cult camp, but with the last minutes of the episode devoted to Walker's rescue of Alex Cahill from the cult camp, it's unknown what has happened to the girl he was supposed to rescue. An even worse example is the movie "Trial by Fire" which ends with Alex being shot in the courthouse and lying near death. Supposedly, the producers were expecting CBS to offer them the opportunity to make further TV movies but low ratings (supposedly due to a football game preceding the movie running an hour longer than anticipated) and CBS shortly thereafter scrapping their Sunday night TV movie has made further TV movies unlikely. INSP network even doctored the movie to edit out the final scene with the shooting because there is no resolution and removing Alex's shooting leaves the story in a position to end without a hitch.
* Probably due to extra seasons being planned but ultimately being cancelled by the [[ScrewedByTheNetwork BBC]], season 3 of ''Series/TheHouseOfEliott'' ended with an unresolved argument between Evie and Beatrice over the direction of the eponymous fashion house.
* The final episode of ''Series/UnnaturalHistory'' ended with the cast in the Mongolian desert, when they hear a strange noise. Jasper and Maggie wonder what the noise was, and Henry suggests the area is "more than just dust and bones".
* ''Series/CriminalMindsSuspectBehavior''. The first season ends with a sadist/masochist killer team forcing team leader Cooper into a SadisticChoice of killing the masochist or the sadist will kill one of his teammates. The choice is right down to the wire, cut to black, gunshot. But, sorry, show was cancelled the previous week, NO RESOLUTION FOR YOU!
* So much for ''Series/TheCape''. Didn't help they reduced the seasons episodes from 13 to 10, and didn't even show the last episode on TV (you had to go to the website to watch it). So die hard fans will never know if the BigBad will ever go to jail, Vince will ever clear his name, or his family will know that he is alive.
* ''Series/ThisIsWonderland'', a brilliant Canadian legal dramedy, ran for three seasons, and ended on ''three concurrent cliffhangers''.
* In the fourth series of ''Series/{{Merlin}}'' Guinevere and (a fake) Lancelot are {{brainwashed}} with magic into kissing each other on the night before Gwen's wedding to Arthur, resulting in Gwen's exile and Lancelot's suicide. Although Guinevere is eventually welcomed back to Camelot by the end of the season and becomes its Queen through her marriage to Arthur, no one (including herself) ever finds out that she wasn't acting of her own volition when she cheated on Arthur, even though it would have only taken a simple conversation with Merlin (who knew that Lancelot was being controlled by Morgana) to clear up the issue (Gwen being smart enough to realize that the bracelet Lancelot gave her was probably the cause of her abrupt change in behaviour). Yet for whatever reason, the writers thought exonerating the pair of them wasn't worth any meaningful resolution, and the fact that Guinevere ''had'' to have found out at some point that Lancelot killed himself isn't ever addressed in any way.
* The short-lived BBC soap opera ''Eldorado'' did this deliberately in the hope that viewers would demand to know what happened next and force an [[UnCanceled UnCancellation]]. It didn't work.
* Recent seasons of ''Series/DoctorWho'' under showrunner Steven Moffat have become known for this, as the writer is known for playing the "long game" and introducing plot threads that are intentionally left unresolved for years. The series has also picked up on the occasional hanging thread dating back ''decades'' (such as a 2013 episode, "The Name of the Doctor" that answered questions dating back to ''the very first episode in 1963'').
* ''Series/{{Alcatraz}}'': The final episode ended with Rebecca having been shot and [[spoiler:seemingly dying on the operating table]], and no indication what would happen to the 63s who were still at large.
* The ''Series/TheAmandaShow'' had a recurring skit called "Moody's Point" which was a parody of teen angst shows. It had a twist that Moody was switched at birth and wasn't the real Moody and the episode ended before we could be introduced to the real Moody. ExecutiveMeddling cancelled the show at that point and Dan Schneider later [[http://danwarp.blogspot.com/2008/05/faq-what-happened-with-moodys-point.html wrote in his blog]] that he doesn't even know who the real Moody is since the show was cancelled before he could write the script.
* In ''Series/GameOfThrones'', it is never revealed who sent the assassin to kill Bran Stark. The book series reveals that it was [[spoiler: Joffery]], however in the TV series it is never mentioned, and since nearly everyone who would care is dead the question was dropped.
** The seventh season eventually ends up implying that [[spoiler: Littlefinger]] sent the assassin, which creates something of an AdaptationInducedPlotHole since the timeline for this to have been planned by that particular person is not ''impossible'', but pretty questionable.
* To its credit, ''Series/{{Forever}}'' did resolve what happened to Abigail, the identities of Abe's birth parents, and the fate of the ship Henry was sailing on during his first death. But it ended its only season with no answers about the source of the immortality curse or how Henry can break it. Along those same lines, the evil immortal Adam is immobilized but still alive, and could be a threat later on if he dies again, but we won't know how so. As to whether or not Henry ever told Jo his secret, the show ends right when he's confronted with evidence, and though the dialogue implies he will tell her, we ultimately don't know for sure.
** WordOfGod attempted to clear some of this up on Twitter after the cancellation (e.g. Adam would return with the help of a third immortal, and Jo would become a SecretKeeper), but not much else -- in fact, some tidbits raised even ''more'' questions.
* Creator/TheBBC's [[Series/TheTripods adaptation]] of John Christopher's ''Literature/TheTripods'' trilogy was left hanging at the end of the second series, which adapted the second book and ended with a massive cliffhanger. A third and final series had been scripted but was cancelled due to the same hostility to SF and fantasy among the BBC's leadership that saw ''Series/DoctorWho'' gradually smothered at around the same time.
* The Season 2 {{Cliffhanger}} finale of ''Series/{{Rosewood}}'' came right up to the edge of resolving the UnresolvedSexualTension between the main characters. Since there will be no Season 3, we'll never know what would have happened.
* ''Series/TheKnightsOfProsperity'', about a group of friends trying to rob Music/MickJagger, was cancelled partway into its first season (with the remaining episode airing over the rest of the year), ending with them almost robbing, and almost getting caught robbing Mick Jagger, then deciding not after meeting him in person and finding he's actually a nice guy, and deciding to rob Creator/RayRomano instead after meeting him and finding him to be a jerk.

* ''VideoGame/HalfLife2: Episode Two'' ends with a huge one. The leader of the resistance and your ally Eli Vance is brutally killed by some Combine Advisors. By sucking out his brains, the Combine learned everything he knows about the resistance and info about the missing cargo ship The Borealis. The game sadly ends with his daughter Alyx crying over his corpse. Not only that, we never learned why the Combine are interested in The Borealis, or the fates Judith Mossman and Barney, or even The G-Man's cryptic warnings about "Unforeseen Consequences." The original plan Valve had was to make three episodes in the span of three years, but they never released Episode 3 for unknown reasons. It's baffling because Valve actually hyped it up in several interviews prior to Episode 2's release and even in Episode 2's commentary. Now they constantly avoid talking about it altogether when asked about it. Until Valve officially confirms the follow up now possibly labeled Half-Life 3 by fans, we are left hanging.
* The ''Franchise/MetalGear'' saga surprisingly avoided this problem. The fourth game filled up pretty much all plot holes, with the exception of [[spoiler:Fortune's LastStand]] in the second game. According to WordOfGod however, it was originally supposed to be played straight, with ''VideoGame/MetalGearSolid2SonsOfLiberty'' being the last game chronologically in-universe; so whether or not Metal Gear counts as an example depends on whether one wants to invoke FanonDiscontinuity.
* Of course, due to a ''buttload'' of [[TroubledProduction behind the scenes problems]], ''VideoGame/MetalGearSolidVThePhantomPain'' is an absolute mess. From a narrative standpoint it's a chaotic heap of unresolved plot threads barely held together by {{Voodoo Shark}}s, {{Plot Hole}}s, {{Remixed Level}}s, and an [[CutShort entire final act that went unfinished]] (it only exists as a slideshow narrated by the developers in the special edition of the game). That said game somehow managed to ''actually be good'' in spite of this is nothing less than awe-inspiring.
* James Bond game ''VideoGame/BloodStone'' ends with a TomatoSurprise that could been resolved in a new game, also the credits start with James Bond will return... But we know Bizarre is done for good and the next Bond game won't follow this one. You could however stretch things up and pretend somehow that Skyfall's villain was TheManBehindTheMan.
* ''VideoGame/FinalFantasyVII'' has references to "Techno-Soldiers" replacing human agents of Shinra early in the game, but is never elaborated on and is forgotten once Sephiroth is introduced into the game. It is believed by many fans that the ''original'' plot of the game would have revolved around a TurnedAgainstTheirMasters scenario, which was abandoned in favor of Sephiroth. The techno-soldiers themselves finally turned up in ''VideoGame/DirgeOfCerberus'', and even ''that game'''s storyline is an example of this trope with its secret ending, [[spoiler:where [[Creator/{{Gackt}} Genesis]] [[EarlyBirdCameo Rhapsodos]] appears in a cave and flies away with Weiss in his arms, his motives and goals still unknown. [[VideoGame/CrisisCore And the next game he appears in is a prequel.]]]]
* Early in ''VideoGame/FinalFantasyVIII'', the heroes are assigned to help the city of Timber gain its independence from the Galbadian Republic. This storyline is quickly folded into the main plot, but the question of whether Timber becomes free in the end is never addressed. However, since the Timber mission was a low-paying and therefore low-importance goal, when the sorceress showed up and became a threat to Garden and the world itself, it sort of makes sense that no-one cared about that so much when the main plot kicked off.
* ''VideoGame/FinalFantasyXII'' at some point completely forgets to resolve the Occuria situation. Yeah, the Sun-Cryst is destroyed, but why can't they make another? Why do they just seem to give up without any word? The sequel does not address this at all either. If the canceled sequel ''Fortress'' might have expanded on this issue is now a mystery for the ages.
* At the very end of ''VideoGame/BaldursGate: Dark Alliance II'', the player sees an ominous-looking cutscene showing the rise of a new BigBad. This was intended to be a teaser for ''DA III'', which was never made. ''VideoGame/DungeonKeeper III'' suffered the same fate.
* The ''VideoGame/{{Fallout}}'' series has the Followers of The Apocalypse in the first game and the very similiar tanker vagrants in the second game, both are due to bugs. Although ''VideoGame/FalloutNewVegas'' does feature the former, so now we know their canon fate. The ''VideoGame/{{Fallout 3}}'' expansion ''Broken Steel'' leaves Colonel Autumn's fate unresolved if you let him walk out of the purifier. Was he killed or captured, or did he leave the Wasteland entirely?
* ''TabletopGame/{{Warhammer 40000}}: VideoGame/DawnOfWar'' ends with Brother-Captain Gabriel Angelos swearing to [[spoiler:defeat the demon he had [[NiceJobBreakingItHero accidentally unsealed]] from the [[SealedEvilInACan artifact sealing it]]]]. Neither Gabe nor [[spoiler:that particular demon]] have been seen for the three expansion packs that followed. The plot line is completed as of ''Dawn of War II: Retribution''.
* ''Dreamfall'', sequel to ''VideoGame/TheLongestJourney'', tied up about two of the many different plot threads left hanging over the course of the game. It doesn't even tell you what happened to the main characters. To be fair, though, it is the middle part of a trilogy. With the episodic release of Dreamfall:Chapters, the fates of the main characters were quickly resolved and slowly but surely a lot of the other plot threads are being tied up.
* The InteractiveFiction version of ''VideoGame/TheHitchhikersGuideToTheGalaxy'' ends with [[spoiler: Arthur setting foot on the planet Magrathea]]. The game promises a sequel, which of course never came.
* ''VideoGame/GearsOfWar'' series:
** ''Gears of War 2'' is ''paced'' from beginning to end by dropping the latest subplot and introducing a new one.
** ''Gears of War 3'', which WordOfGod confirms is definitely the last game in the series, does do a good job of wrapping up each characters' personal plot arcs and finally explains Imulsion and the Lambent, but still leaves unaddressed the Sires[=/=]New Hope Facility sub-plot from the second game, the true nature of the Locust (if any), as well as the question of who or what Queen Myrrah really was. This was solved with old forum posts and the tie-in comic ''The Slab''. Though, Adam Fenix's disk is never brought up again.
* ''VideoGame/NoMoreHeroes'' really ends with just Travis Touchdown and Henry striking each other by the Santa Destroy flag. This leaves many things to consider, such as what the UAA really is, who Travis's parents were, who Darkstar was, and, of course, if the events affected the video game's real world or if it really was Silvia's daughter Jeane day dreaming about a picture. Some, but not all, of these questions are answered in ''VideoGame/NoMoreHeroes2DesperateStruggle''.
* The original Japanese release of ''VideoGame/{{MOTHER}}'' ended like this. After sending [[SpellMyNameWithAnS Giegue]] packing, Ninten and his party start to walk away from the battle field... and then the scene pauses, the credits roll, and you're left with a "To be continued..." for your troubles. The [[NoExportForYou then-unreleased American localization]] averted this, adding an epilogue that gave a proper resolution for all the characters in the game; this was kept in the game when ''[[UpdatedRerelease Mother 1 + 2]]'' was released on the Game Boy Advance years later.
* ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]'' has one of your allies, Spen Jankowski, in a different area of the same operation as you. He disappears on the site. Eventually, the support guy stops mentioning him, and he never comes up again. You finally find his body in ''Project Origin''.
* ''VideoGame/{{Persona 4}}'' seems to be doing this ''deliberately''; while the main plot is resolved well enough, there's a fair few details, large and small, left completely dangling. [[spoiler: The largest one by far is that, despite defeating the thing that was shrouding the "Other World" in fog, the TV-based portals to the other side '''''still function''''', in stark contrast to the cessation of the Dark Hour after the BigBad of ''VideoGame/{{Persona 3}}'' is defeated. The cast themselves briefly note that this has potential issues for the future.]] It's quite possible that Creator/{{Atlus}} has simply left hooks in [[CashCowFranchise for another sequel]]. One seemingly Left Hanging detail is actually exploited by the game: [[spoiler:in order to get the game's GoldenEnding, you have to ''refuse'' the Good Ending that the game hands you in order to find out where the protagonist and Adachi got their Personas, a detail you may have completely forgotten about]].
* When ''VideoGame/MegaMan9'', and later ''[[VideoGame/MegaMan10 10]]'', were announced, people wondered if Capcom would ''finally'' fully tie together the Classic series and the SequelSeries ''VideoGame/MegaManX''. [[MissionPackSequel It didn't happen]]. If an ''X9'' is ever announced, people will probably ask [[VideoGame/MegaManZero about the Elf Wars]].
* ''VideoGame/MegaManLegends 2'' ended with Mega Man Volnutt stuck on the moon, and Roll Caskett and Tron Bonne working together to rescue him. This was left to hang for an entire ''decade'', and with the cancellation of ''Mega Man Legends 3'', it seems it's not going to be resolved any time soon.
* The ''VideoGame/ViewtifulJoe'' games were planned to be a trilogy, with a character in the first game even outright telling the protagonist that he'd have two more fights for justice on his hands in the future. This made it all the more incredible and infuriating when come the end of the second game, [[spoiler: Joe's father turns out to be an evil villain, powered by a mysterious black V-Watch he acquired somehow, the superpowers and other craziness of the movies have somehow made their way into the real world, and a fortress of evil rises out of the earth in the distance, signalling the final and oh-so-presumably-epic battle and the answers to all our questions...]] but then, OH DEAR, the studio shut down, and we never got closure on any of that, or the overall story of the games.
* ''VideoGame/{{Hydrophobia}}'' ends abruptly without dealing with a lot of the plot points: the credits roll just as the heroes encounter a new danger, you never find out about the person you're trying to save, the full details of what the heck was going on is never revealed, as is info about the BigBad and the organization behind the plot. You can get the bare bones from the various collectible documents spread about the game, but that still only gets you the lead-in to a possible reveal, which never comes.
* The original ''VideoGame/DeadRising'' left off with Frank and Isabella escaping the mall and defeating an insane military general. However, Carlito spread infected orphans all over the country and Frank himself is infected. It also isn't mentioned as to whether or not Otis escaped with the survivors successfully (and there's the fact that a few of the survivors were infected anyway). The sequel pretty much confirms that the country-wide infection has more-or-less succeeded. ''Case West'' reveals that Frank and Isabella have survived, Frank is suppressing his zombification via Zombrex, and the two are hard at work to get to the bottom of the whole mess.
* Mio's fate in the canon ending of ''VideoGame/FatalFrameIIITheTormented'' is left deliberately ambiguous, [[spoiler: but given [[FailureIsTheOnlyOption how these games tend to go]], she probably didn't survive.]] In the fourth game, the question of whether or not [[spoiler:Misaki]] lived is also left unanswered.
* The bizarre ending to ''VideoGame/MonkeyIsland2LeChucksRevenge'' has never been resolved -- by the time ''VideoGame/TheCurseOfMonkeyIsland'' came around, Ron Gilbert was no longer working on the series, and the devs for that game decided to HandWave it away rather than come up with their own explanation. A WordOfGod answer to what happened doesn't seem likely, either, as Ron Gilbert seems unwilling to share this (or the true Secret of Monkey Island -- they appear to be connected) unless he can make a game out of it.
* ''VideoGame/ReturnToKrondor'' had an ending that was clearly intended as a SequelHook. Let's see...[[spoiler: Sidi is still alive and active, and puts the amulet back together. He intends to release the Dark God into Midkemia and the amulet is clearly a part of his plan. Meanwhile, there is the matter of the Crawler still alive and and active...somewhere.]] A sequel has never been made.
* ''VideoGame/{{Touhou}}'''s ''Hisoutensoku'' has three story arcs centered around three heroines searching for the owner of [[MacGuffin a giant shadow/silhouette]]. Only [[{{Miko}} Sanae's]] arc has sufficient closure - that she had, in fact, found her "giant." [[IdiotHero Cirno]] gets sidetracked twice by [[TheTrickster Marisa]] and ends up fighting one of Alice's experimental spell cards, pegging it as her ''Daidarabotchi''. [[IronButtmonkey Meiling]] gets it worse: [[spoiler:either she dreamed the whole thing, or she did see something but never even got to her first stage battle.]]
* ''VideoGame/LegacyOfKain'' has lain dormant since 2003's ''Defiance'', with the Pillars of Nosgoth still destroyed and the future of the world uncertain. Crystal Dynamics' shift to the ''Franchise/TombRaider'' series, the series' creator's move to Naughty Dog, and the [[AuthorExistenceFailure death of Tony Jay]] make the chances of a resolution appear unlikely.
* The details of Nero's background in ''VideoGame/DevilMayCry 4'' remain very blurry. We still don't know whose son he is (claims that he's Vergil's remain {{Fanon}}), when or how he got his RedRightHand, or how much Dante knows about himÖ and apparently we will never know since Capcom decided to let Ninja Theory make a [[VideoGame/DMCDevilMayCry "rebirth"]] of the series rather than a sequel.
* ''VideoGame/DMCDevilMayCry'' game ended with Dante defeating Virgil to keep him from taking over the BigBad position to rule humanity. Despite this, however, demons have now been outed and the world is in a state of confusion and chaos with it being uncertain how things will turn out. If that wasn't bad enough, the DLC for Virgil shows him casting his empathy aside and amassing an army of demons for his own conquest. What happens next? No clue, as the series went into hiatus after this game released. With no word from Capcom on if they'll continue this continuity or not.
* This trope is one of the many complaints regarding ''VideoGame/MassEffect3'''s ending - no matter what you did throughout the entirety of the series, you receive one of three endings with no closure outside of the fate of the Reapers. "Side" missions such as [[spoiler: using/sabotaging the genophage cure, whether the Quarians or Geth (or both) were saved, and the fate of the Rachni]] have no narrative consequence outside of War Assets, and the fate of your squadmates is left completely unknown.
** [[spoiler: Another common complaint is that Shepard only can survive in the Red Ending if you do ''everything'' right, but even then, its a split second of his/her torso taking a laboured breath in a pile of rubble. SmashCut to credits, leaving his/her fate completely unknown.]]
** [[spoiler: However, it has been addressed with the release of the [[AuthorsSavingThrow Extended Cut DLC]], pretty much showing how the galaxy recovers from the war, [[RetCon changes the mass relays from being destroyed to being damaged]] and, with the exception of the Destroy ending with the lowest EMS possible on these two cases, Shepard's squadmates are safe.]]
* ''VideoGame/{{Killzone}}'':
** The ending of ''Killzone 3'' abruptly smashes you in the face with the credits ''immediately'' after the climax. There's a short [[TheStinger stinger]] scene in the middle of the credits which answers ''one'' minor question but that's as far as it goes. [[spoiler: As far as the player knows: 1. The Helghast fleet has been mostly destroyed. 2. The nuking of Stahl's flagship on the surface of Helghan triggered a massive Petrusite chain reaction which appeared to wipe out ''all life on the surface'', with the obvious exception of Stahl and a few of his soldiers as seen in Stinger mentioned. 3. Considering how powerful the Helghast weapons have become, and how some of their ships warped to Earth, it's possible the attack on Earth has already begun. 4. The ISA forces left at Helghan were either destroyed by the petrusite reaction or stuck flying around the planet in fighters incapable of warp travel, so they probably have no way to get to Earth.]]
** ''Killzone Shadowfall'' dealt with the aftermath of the ending to ''Killzone 3'', only to leave players hanging about the fate of the cold war. No new sequels have been made, and no information about the original protagonists has been given.
* ''VideoGame/FreedomForce vs. The Third Reich'' ends with Alchemiss/Entropy meeting the living embodiment of Energy X who implies that she still has a job to do. The third game in the series, which was intended to cover modern and Iron Age comics, was never greenlit.
* ''VideoGame/GoldenSun: The Lost Age'' resolved most of it's major plot points, but left a few smaller plots open -Namely Anemos, Sheba's origins, and the ultimate fate of [[spoiler: Alex]]. The sequel, ''VideoGame/GoldenSunDarkDawn'', revealed that [[spoiler: Alex survived]] but otherwise did not address any of these points, and even introduced a few more: The quest Takeru is on, what happened to Felix, the Tuaparang Emperor, and especially [[spoiler: The Psynergy Vortexes, particularly the huge one that has manifested over Matthew's home. Oh, and Alex is still TheUnfought.]]
* What happened to Alis(a) after ''VideoGame/PhantasyStar Gaiden'', and what exactly was the threat she was returning to Algol to face? At the time it was made, she was supposed to return as the protagonist of ''Phantasy Star IV'' and this game was the set-up for that, but when they ended up going with a different plot for that game, they just left this unresolved.
* [[EpisodicGame Episode 2]] of ''VideoGame/SonicTheHedgehog4'' ended with [[VideoGame/SonicCD the Little Planet]] not being restored. [[http://www.joystiq.com/2012/03/13/no-more-sonic-4-episodes-planned-after-episode-2/ No Episode 3 for you!]]
* ''[[VideoGame/TheForceUnleashed Star Wars: The Force Unleashed II]]'' ends with Darth Vader captured by the Rebellion and the Rebel fleet makes the jump into hyperspace, little knowing that Boba Fett is following them. Unfortunately, the lack of sales, combined with Creator/LucasArts closing in 2013, suggests that it's not going to be resolved any time soon. At least Vader is somehow SavedByCanon.
* ''VideoGame/EpicMickey2ThePowerOfTwo'' ends with Mickey and Oswald saving the wasteland and defeating the Mad Doctor. The post credits scene features [[spoiler: all the Petes of the wasteland getting together and plotting something while holding Gremlin Prescott hostage.]] However, due to the game's poor sales which led to the closing of Junction Point Studios, a third game is highly unlikely.
* VideoGame/AssassinsCreedIII left ''three'' unsolved mysteries: Connor's ultimate fate, Juno's true plans for the world, and that mysterious voice at the very end. Only the last was ever resolved (an Abstergo tech guiding one of the company's Animus users). In Black Flag, Connor is only briefly mentioned with no new information, and Juno for some reason is helplessly trapped in Abstergo's network, only saying that "perhaps the Vault was opened too soon".
* The Epic story of ''VideoGame/{{Shenmue}}'' ended on (perhaps) the 4th, of it's planned 11 chapters, when it was cut-short after it's sequel. For a multitude of reasons but mainly because Creator/{{Sega}} could no longer afford to make the games any more. Leaving not only the whole driving revenge plotline hanging but introducing us to new characters that would apparently answer many questions about the mysterious {{MacGuffin}}s, character motivations and if the world was MaybeMagicMaybeMundane. Eventually, a Kickstarter was announced for Shenmue III, which was funded within 12 hours, guaranteeing that the series would finally see it's conclusion.
* The entire continuity of ''VideoGame/AloneInTheDarkTheNewNightmare''. The game ends with a strong SequelHook, as [[spoiler:Shadow Island and its gate to the shadow world are destroyed and [[TheManBehindTheMan Lamb]], who arranges a cover-up, now has the Abkani tablets and knows the location of at least two more gates]], but no direct sequel has been ever made. The planned comic book series was to follow Carnby and Aline after the events of Shadow Island, but only the first issue was ever made.
* In ''VideoGame/TelepathTactics'', Igor Bloodbeard and his bandits are the major antagonists of the first arc, but he's never confronted directly, and his forces end up vanishing from the plot rather abruptly with no proper resolution. His subordinate Fera does show up in the epilogue, however, so this may be an intentional SequelHook.
* In the two ''VideoGame/Left4Dead'' games and their accompanying comic, the Left 4 Dead 1 gang eventually get an ending that's fairly easy to take as conclusive, but the Left 4 Dead 2 survivors have their fate left much more ambigious. While the final canon campaign, The Parish, serves well as a close to the series overall due to it's excitingly paced finale and satisfying visual payoff in the ending cut-scene (compared to most other campaigns), all of the foreshadowing regarding the army's vile treatment of carriers makes it hard to take the survivors' final escape as being a conclusive end to their trials. With no further DLC for Left 4 Dead 2 on the horizon, and Left 4 Dead 3 unconfirmed, it's not looking like we'll know what happened to Coach and the gang for a long while, if ever.
* Although ''Videogame/FiveNightsAtFreddys4'' resolves most of its plot threads, the biggest one left unsolved is the locked box that appears at the end of Night 7. According to Creator/ScottCawthon, it contains, "all the pieces [of [[JigsawPuzzlePlot the story]]] put together," and though he planned to include the means to open it in an update, he eventually decided to leave the box as it is after noticing how the fanbase, unlike with the other games, hadn't fully solved the story yet (and, as of February 2016, ''still haven't'').
** And now, with Scott having indefinitely shelved the sixth installment due to needing a break from the series, it's fairly likely that we'll never get a follow-up on [[SequelHook the various dangling plot threads from]] ''[[VideoGame/FiveNightsAtFreddysSisterLocation Sister Location]]'', most notably [[spoiler:Michael Afton going after his villainous father for revenge]].
*** Averted after the release [[VideoGame/FreddyFazbearsPizzeriaSimulator]].
* ''VideoGame/DisneyInfinity'': The ending of the story mode of the Marvel Battlegrounds Play Set ([[spoiler:which implies that Loki and Ultron were in league with Thanos, and that Thanos is coming after the Marvel heroes]]) was clearly a SequelHook, but the fact that ''Infinity'' has ended production means that this twist in the game's plot likely won't be leading anywhere anytime soon.
* The ending to ''VideoGame/SlyCooperThievesInTime'' is a DownerEnding {{Cliffhanger}} with [[spoiler:Sly trapped in the past]] and an unresolved plot point into why [[spoiler:Penelope pulled a FaceHeelTurn and continues to stalk her ex-boyfriend with postcards]]. Unfortunately, a fifth game was never announced, and over a year later, Sanzaru confirmed the franchise has been cancelled.
* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' has a player-dependent example ó players who refuse to take their time and decide to [[SequenceBreaking rush straight to the]] FinalBoss will be able to finish the game, but won't learn anything about the world, the nature of this Link's true identity, or the role Zelda had in the backstory.
* VideoGame/HauntingStarringPolterguy: After the Sardinis flee the fourth house, [[spoiler:we never get to see them again and their fate is completely left ambiguous. However poltergeist Polterguy suggests that he will continue with his haunting but he does not specify where he will do this.]]
* VideoGame/GrandTheftAutoIII left two plot points hanging (and those wasn't ever answered by future games either). The first one is the disappearance of Donald Love (which is never revelead the reason or where he went) and the second one is regarding the ambigious last scene in which Maria Salvatore may be or may be not have been KilledOffscreen.
* Much like ''Disney Infinity'' above, TheStinger of the main campaign of ''VideoGame/LegoDimensions'' [[spoiler: showing an unseen character picking up a bit of Lord Vortech and getting corrupted by it, clearly setting something up]] was never to be followed up on as the franchise ended up being abruptly cut short as well.

[[folder:Visual Novels]]
* ''{{VisualNovel/Remember11}}'': The characters are basically out of danger, and free to start piecing together the many lingering mysteries surrounding their experience. Then comes an implied imminent infanticide and the credits.
* ''VisualNovel/ZeroEscape'':
** ''VisualNovel/NineHoursNinePersonsNineDoors'': Though you may not know it: [[spoiler:the True ending seems to imply Junpei finds Akane, right? Wrong. He doesn't. He spends the rest of his life looking for her, and she goes off on some huge, grand scheme that the director only mentioned in passing.]]
** The sequel ''VisualNovel/VirtuesLastReward'' is even worse: [[spoiler:the entire game being training set up by Akane and Future!Sigma to develop Sigma and Phi's esper abilities to send them to the past and prevent the Radical-6 outbreak. Naturally, the game ends with them jumping back in time, and neither epilogue takes place when any of the participants willing to divulge information have yet been in the Mars mission test site]]. Most of these unresolved hooks are directly or indirectly [[SequelHook setting up for the third game]], but at least a few of them, not the least being [[spoiler:the identity of "?"]], are unaddressed.
** Not to mention ''VisualNovel/ZeroTimeDilemma'', which leaves a good bunch of plot threads unresolved. [[spoiler:Who was that religious fanatic? Was he/she found by Crash Keys, or did they doom humanity? Did Carlos shoot Delta or not? What happened to D-Team after the Payoff confrontation with Delta? [[note]]We are explained what happens to the other teams through in-game files, but not D-Team.[[/note]]]] None of these questions are addressed in the story, and unless [[TrilogyCreep a fourth game suddenly comes out of nowhere]], we're unlikely to ever get the answers.

* Pick a comic listed on OrphanedSeries. Nearly all of them stopped in the middle of ongoing storylines.
* ''Webcomic/AbstractGender'' died before most of the ongoing storylines (including the MythArc) could be ultimately resolved.
* ''Webcomic/RumorsOfWar'' frequently ends a StoryArc without resolving all of its plot threads. This is generally viewed as intentional on the part of the author. Not that it's any less frustrating to be left wondering WhatHappenedToTheMouse
* In ''Webcomic/{{Sonichu}}'', the characters had just reached big final showdown with Mary Lee Walsh; after her defeat they release the most powerful evil being in the comic, Count Graduon, at which point... the creator angrily announces he hates his greedy fanbase, swears off the internet, and abandons his website.
* As Tessa Stone hasn't been heard from in months, ''Webcomic/HannaIsNotABoysName'' is like this, at least for now. The comic stopped updating when every major character was in mortal peril. [[spoiler: Zombie, Hanna, and Toni are locked with a questionably sane Ples (who just whipped out a gun and fired it), and Conrad's trapped with Lamont, Worth, and Adelaide trying to get to Hanna and escape Abner. Oh, and Veser ran out a while ago, and we never found out where he went.]]
* ''Webcomic/RPGWorld'', the heroes invade Galgarion's headquarters and make it to him for a final battle. Everyone's about to throw down and...it just stopped. A combination of creator, Ian J, going into animation and backlash from his fans on certain things they didn't like in the story resulted in him quitting the webcomic entirely, leaving the story unfinished after a seven year run (2000-2007). What's more there was a subplot going on that Rika's robots had stumbled upon a time machine [[spoiler: meaning there could possibly be a way to prevent her from being killed by Galgarion]]. But the series stopped before it could go anywhere.
** Eventually when Ian got his show, ''WesternAnimation/OKKOLetsBeHeroes'', greenlit years later after becoming an animator. He dedicated an episode to Hero and Galgarion ultimately resolving their feud and Hero going back home to Cherry where they later have a child. It was about as much closure fans were gonna get of the series despite the other plotlines that were still going on since the webcomic ended.
* ''Webcomic/GirlsWithSlingshots'' ended with Hazel and Zach sorting out their relationship and settling as BetterAsFriends, but there were several plotlines that were left unresolved: Will Hazel move in as a roommate with her DoggedNiceGuy Vincent, despite Jamie thinking (with justification) that it's a very bad idea? And what's Vincent's side of the story in this? What about the hints that [=McPedro=] is an alien? Although, the author has stated that the story may continue in another form, so these plotlines may get a future resolution.
* ''{{Webcomic/Homestuck}}'' ends in this manner, with all of the plot threads that had been developed over the last couple years being abandoned in favor of the ending that had been planned out and worked on for years. However, [[DownplayedTrope the credits sequence released six months later ended up resolving many of the threads]], and an Epilogue, which has been hinted to resolve the remaining questions (such as [[spoiler:what happened to Vriska after the final battle, as well as how exactly Caliborn's Masterpiece ties into the plot]]) is expected...[[VaporWare eventually]].

[[folder:Web Original]]
* The X-Entertainment 2008 Advent Calendar's last update was the 22nd... right before the traditional final battle. Great.
* ''WebVideo/LittleWhiteLie'' featured a major cliffhanger...and then the creators lost their money and most of the people moved and scattered around the country.
* The ending to ''DarthWiki/CandleCove'' is a mixture of this and TheReveal. [[spoiler: The last person discussing the long-forgotten children's show explains that ''Candle Cove didn't exist at all'', and that anyone who watched the show was just watching static for half an hour.]] It turns into ParanoiaFuel when the participants in the story remember some profoundly scary things from the show.
* The ''Toys/{{Bionicle}}'' web-serials ceased being updated long ago, for the simple reason that the writer didn't have time to continue doing them, leaving about a dozen or so different plot-lines hanging, some of them in their very early stages. And as these were the sole story-sources after the cancellation of the toys, comics, books and movies, this effectively means the entire franchise ended this way.
* Chris Niosi may NEVER stop hearing backlash from fans about how he ended ''WebAnimation/TVTomeAdventures''. Granted, he WAS planning on creating a fourth season, but [[ScheduleSlip after he went to college,]] he had less time for the series and the show was cancelled. Still, most of the loose ends can be answered by scrounging Niosi's Website/DeviantArt page. It's a shame, too, since season 4 [[WhatCouldHaveBeen would have been awesome.]]
** [[TheRemake Fortunately, Chris Niosi has rebooted the series in the form of TOME, so the unused material might actually end up being used if all goes well.]]
-->'''Gamecrazed''':''I'm just a virus...''
* Because of a CreatorBreakdown, ''WebVideo/DemoReel'' ended up leaving a few things unanswered, most annoying being Donnie's failed marriage. What did he do to make it die? Did she know about his past? How did they meet? We'll never find out.
* In ''RolePlay/WeAreAllPokemonTrainers'' the PMD-R arc abruptly ended by leaking into Kanjoh-2 due to most of the playerbase losing motivation, though there have been attempts to properly fill the gaps and close the loose ends.
* A number of plots in ''RolePlay/PokemonRiseOfTheRockets'', primarily due to players leaving before finishing what they started--or worse, introducing characters and plots and then not doing anything at all with them. One particular example that comes to mind is Hoenn's liberation from Team Rocket, which was never followed up on again until the [=GM=] decided to do something with it himself--which resulted in complaints from the very player who had left it hanging to begin with!
* In ''Roleplay/TheGamersAlliance'', any plots introduced by players who disappear afterwards will often be left hanging unless some other players decide to carry on the plots and resolve them instead.
* The 13th Season of ''Machinima/RedVsBlue''. [[spoiler:Epsilon-Church deconstructs himself into his fragments, which each go to one of the different Reds and Blues to help them defeat Hargrove's forces, which are about to blast their way into the room they're barricaded in. Church remarks about how the hero who gives his life doesn't get to see the happy ending he helped created. And with the line "Well, ain't that a bitch," the screen cuts to black before anything else happens.]] Season 15, the next season chronologically[[note]]Season 14 is an anthology season with little connection to the ongoing plot[[/note]], picks up well after this point, and the writers have gone on record stating that they don't intend to reveal [[spoiler:how the Reds and Blues escaped the ship]].
* {{WebVideo/Googlebrains}} has a video that just leaves you in thin air about what happens next. There is an ending but they say stuff that adds so much possibility for a continuation.

[[folder:Western Animation]]
* The first and only season of ''WesternAnimation/CloneHigh'' ends with a series of dramatic events, including Joan sleeping with JFK, Scudworth being apprehended by the Board of Shadowy Figures, and all the clones being frozen. The show was cancelled and we never learned what became of anyone.
* ''WesternAnimation/AsToldByGinger'', "Wicked Game" (about Dodie's attempts to break her best friend Ginger's relationship with Darren). This is brought up again in a later episode as an offhand comment, so it's assumed that Ginger, Dodie, and Macy patched things up off screen and deal with it by [[LetUsNeverSpeakOfThisAgain never speaking about it again.]]
* Near its end, ''WesternAnimation/HeyArnold'' got hit by this twice in quick succession. In ''Hey Arnold! The Movie'', Helga confesses her feelings to Arnold, but at the end claims she said it on the heat of the moment. From his unconvinced smile, and the fact that he later flirts with her while dancing tango in "April Fool's Day", it's pretty clear he knows that's not the case. However, he never actually responds to Helga's confession at all. And then, at the end of "The Journal", Arnold finds a map of the San Lorenzo jungle that could lead him to his lost parents' whereabouts. This was intended to be the lead-in to the second ''Hey Arnold!'' film, known as "The Jungle Movie", which would've resolved ''both'' of these questions, but Craig Bartlett's departure from Nickelodeon, coupled with the low gross of the first film, led to the GrandFinale of the series being cancelled. It would be more than a decade before this trope would be [[SubvertedTrope subverted]] with the announcement of ''[[WesternAnimation/HeyArnoldTheJungleMovie The Jungle Movie]]'' going back into production as a two-part TV movie. It's notable that this was only achieved because of a loving fan base. [[SavedByTheFans Fans were intensely driven to help fund the return of the series as a movie]] and it finally picked up speed in the mid 2010's and led to a full resolution. The end result turned out to be just one movie, but with the door open for potential follow-up installments.
* ''WesternAnimation/TheWeekenders'', "Croquembouche" (about Carver in a food essay contest: Tino does his usual end-of-episode [[AnAesop Aesop]] routine while Carver presents his essay on a French cake, which gives the ep its title, and the ep ends with people applauding Carver's speech, without showing if he won or not)
* ''WesternAnimation/AllGrownUp'', "Izzy or Isn't He?" (when the episode ends, you realize they never mention the result of the election that forms a major part of this episode's storyline).
* ''WesternAnimation/ReBoot'' started the "Daemon" storyline during the third season... only to find out that they weren't getting a fourth season. That one was left hanging for years until the TV movie ''Daemon Rising'' (which used "It's About Time!" as part of the advertising). Alas, ''[=ReBoot=]'' ended on ''another'' cliffhanger not long after. Other three movies entered into production, and a webcomic is being done on the official ''[=ReBoot=]'' website to bridge the storyline gap between the old and new material. But then it all ends in ''another'' cliffhanger.
* In the ''Franchise/BattleTechExpandedUniverse'' animated series, the final two-part episode pits the main characters against the bad guys in a Trial of Possession for the main characters' home planet of Sommerset. When it finally breaks down to a hand to hand fight between the bad guy and the hero, it ends with the hero winning the planet... but not the people, including the hero's brother, who were all spirited off the planet. The series was not continued. However, in a novel set in the same universe, the main character shows up nearly 15 years later. He is presented with the temptation to make an unauthorized attack to retake Sommerset, meaning that the Trial of Possession (much like the rest of the series) had little or no lasting effect on the larger ''Battletech'' universe.
* ''WesternAnimation/AvatarTheLastAirbender'' never resolves the question of what happened to Zuko's mom. The SequelSeries to ATLA, ''WesternAnimation/TheLegendOfKorra'', features a character asking the phrase above ''verbatim''. The adressee is ''[[TrollingCreator cut off before she can answer]].'' At least the viewers are given the hint that it was a happy ending. The question is finally answered in a sequel comic book called ''[[Comicbook/AvatarTheLastAirbenderTheSearch The Search]]''.
* The 1990's cartoon ''WesternAnimation/MummiesAlive'' ended with one of the minor characters (who'd been searching for proof of their existence) listening to fellow believers on his own radio show in what boils down into an extended ClipShow. The series was supposed to be picked up for another season, but this fell through due to low ratings.
* ''WesternAnimation/SpiderManUnlimited'' ends with Venom and Carnage-esque symbiotes being spread across the world. A book on Spider-Man mentioned that had the second season happened, Spidey and the resistance would save the day. The class system on the Second Earth would be abolished and Spidey would return to his own planet. Looks like they were going to go back to basics. To twist the knife even further, Unlimited Spidey gets killed off by one of the Inheritors in ''ComicBook/SpiderVerse''.
* ''{{WesternAnimation/Robotix}}'' ended with Nemesis, who had been presumed deceased, still alive in space. If the episodes had been picked up as a full series, he and the other Terrakors would have most likely returned to Skalorr to get revenge on the Protectons.
* ''WesternAnimation/TheSimpsons'' has an odd tendency to start episodes with one plotline [[HalfwayPlotSwitch that somehow activates another]], and what happened to initiate the new plotline is rarely, if ever mentioned again:
** A {{lampshad|eHanging}}ing occurred in the episode "A Tale of Two Springfields" when, after the plot had shifted, a badger who had been living in the dog-house tries to reassert itself, but Homer accusingly tells it that they're onto something else now. The episode ends with the badger [[RuleOfFunny leading an army of badgers to invade Springfield]] when they're [[ThePowerOfRock distracted by a concert]] by Music/TheWho.
** Lampshaded again in a different episode, where a supermarket [[RippedFromTheHeadlines bagging boy strike]] tangentially led to the family going on an African safari. As the family drifts down a dangerous river on a ''very'' makeshift raft, Homer wonders if the strike back home is over. His rant is cut short when they careen over Victoria Falls. After they survive this, they follow a monkey in hopes of finding their way back to civilization... as Homer continues to rant on why those bag boys don't deserve anything.
** Interestingly inverted in one episode where Homer, going crazy with ThrowingDownTheGauntlet to scare everyone, ends up offending someone who ''accepts'' his challenge and he and the family are forced to flee the house while he's waiting on the lawn. At the end of the episode when they return from a failed farming venture, Homer finds his opponent still waiting for him and they end up dueling after all.
** The episode, "Missionary Impossible", with Homer on an island, where he and a girl are at the top of a tower, which is about to fall into a lava flow with them in it. The episode's plot ends there as they get interrupted by a callback to the telethon fundraiser Homer ran away from in Springfield (and a joke about Rupert Murdoch being so greedy that the show's revenue from commercials and merchandise isn't enough).
%%* The first season finale of ''WesternAnimation/XavierRenegadeAngel'' does this on purpose.
* ''WesternAnimation/{{Duckman}}'''s last episode, "Four Weddings Inconceivable", ends with the titular character about to [[WeddingDay remarry]]--until his first wife, who has been presumed dead for the entire series, shows up. According to [[http://en.wikipedia.org/wiki/Duckman the series' entry]] at Wiki/{{Wikipedia}}, "Writer Michael Markowitz noted (in Sep 1998): "We never formally planned Part II... and I'll never tell what I personally had in mind. I'm hoping to leave it to my heirs, for the inevitable day when Duckman is revived by future generations. Ah, the Spandex suits they'll wear, the hovercrafts they'll fly!"
* The French and Vietnamese dubs of ''WesternAnimation/BeastWars'' both ended after the second series, leaving fans with a massive, unresolved {{cliffhanger}}.
** One could argue that the series ''itself'' ended up like this. While the ''main'' plotline was largely resolved, the nature of the Vok aliens (who instigated some of the series' biggest episodes) and the origins of Tarantulas were not explained. This was a result of the series being [[ExecutiveMeddling rushed to completion so that the sequel]] ''WesternAnimation/BeastMachines'' could begin. Simon Furman eventually revealed that the season 3 finale was originally to be a 3-parter that would end on a cliffhanger, leading in to season 4 - this SeasonFinale was to explain Taratulas' origins in detail and his motivations for hating the Vok (and would likely have resulted in Tigerhawk gaining a bigger role as well instead of [[DroppedABridgeOnHim being thrown conveniently under the bridge]]). The plot was rushed, and unexplained aspects of the story were left to the comic continuation.
* ''WesternAnimation/RoughnecksStarshipTroopersChronicles'' details in its final season the invasion of Earth. AnyoneCanDie is established fairly quickly, the queen is on Earth, and the whole thing seems to be heading to a massive climax. Then Sony cut the funding three episodes from the end.
* The ending of the second season of ''WesternAnimation/LegionOfSuperHeroes'' revealed that Brainiac was still alive and well ("Evil does not die; it evolves!") But the show didn't get a third season.
* ''WesternAnimation/SonicSatAM'': The final episode of Season 2, "The Doomsday Project" ends with Robotnik's sinister plot to launch doomsday pods all over Mobius ruined, and the city of Robotropolis can return to Mobotropolis as Dr. Robotnik is left to an unknown fate. Sonic and Sally realize their emotions for each other and kiss. But that's not it--Snively tells Sonic not to be so happy as it's now his turn, and a mysterious red-eyed figure (revealed in a later interview to be Ixis Naugus) laughs threateningly. Sadly, the show was canceled after Creator/{{Disney}} took over ABC.
* ''WesternAnimation/TheSpectacularSpiderMan.'' Did you enjoy seeing all your favorite major and minor characters from classic Spider-Man history and can't wait to see how they develop under the direction of writer Creator/GregWeisman? Want to know what kinds of juicy [[LoveTriangle drama]] will take place now that Gwen [[TheGlassesGottaGo hotted up]], and is stuck with a seemingly [[AvengingTheVillain revenge]]-[[YouKilledMyFather bent]] Harry Osbourn? Just how in the world did Norman survive that nasty explosion and what he's planning next? Does Peter end up with MJ or Gwen? [[ILetGwenStacyDie Does Gwen even live?]] Tough luck, tiger. The rights for Spidey being fought over between Sony and Disney following the latter's Marvel buyout in 2010 meant the show got cancelled.
* ''WesternAnimation/SpiderManTheNewAnimatedSeries'': Peter defeats the Gaines Twins, but his friends Indy, is injured thanks to them tricking Peter into attacking her. Harry, who was starting to come around that Spider-Man might not be so bad, goes back to hating him and Peter ultimately quits being Spider-Man and throws the costume into the Hudson River.
* "Things Change", the final episode of ''WesternAnimation/TeenTitans'', was about two things. First, it was about Beast Boy finding a Terra look-alike and trying to figure out if it was really her. It was later [[AllThereInTheManual confirmed it was her]] in the comic series ''ComicBook/TeenTitansGo'', but the episode itself leaves it ambiguous; fair enough, the moral was having the strength to move on from the past...that said, the second plot is about a completely unexplained conflict between the other four Titans and a random white chameleon thing. [[GiantSpaceFleaFromNowhere It's never explained what it is, where it came from, why it's causing trouble, or how the Titans will catch it and defeat it.]] And the MadeForTVMovie that followed [[WhatHappenedToTheMouse never once mentions it.]]
* The second season of ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' has a subplot regarding the return of Surtur, the fire demon, and the possibility that he will cause Ragnarok to destroy the Earth. In two episodes, Surtur wipes out the dwarves of Nidavellir, enslaves Amora the Enchantress, and slaughters Korbinite aliens. A bonus episode on one of the show's [=DVDs=] features copious buildup to a confrontation between the Avengers and Surtur. However, since the show didn't receive a third season, this confrontation ends up never taking place.
** There were actually several plot threads that were never fully resolved thanks to the canceling of the show. Surtur was just the most noticeable one. Others include Captain America's arrangement with Hela, Maria Hill leading the heroes toward ComicBook/CivilWar, Hawkeye's love life, the fate of Princess Ravana, Hulk's eventual return to the team, capturing the last of the breakout villains, Stark industries's woes, Wonder Man's possible return, and Ronan the Accuser escaping custody.
* The ''WesternAnimation/SilverSurfer'' cartoon [[ShortRunners ended with thirteen episodes]], because [[RealLifeWritesThePlot Marvel went bankrupt]]. Episode 13 featured Thanos ''destroying all of the cosmos''. The second season was meant to fix this.
* The ''WesternAnimation/OhYeahCartoons'' short "Planet Kate" ends on a cliffhanger. We never find out what the alien dogs' mission is or why the map Kate made for a homework assignment happened to fit perfectly as the other half of a real map.
** Likewise, ''WesternAnimation/TheModifyers'' ended with Agent Xero and Mole managing to reclaim the All-Seeing Eye but she loses her communication ring which the villains, who only know her by her other persona, Lacy Shadows, find on the floor.
* ''WesternAnimation/TronUprising'' seems to have ended this way. This means that we never find out how Clu managed to capture Tron and turn him into Rinzler, if Mara and Zed ever found out that Beck was the Renegade, if Beck ever proved to them that he did not kill Abel, if Paige ever underwent a HeelFaceTurn and joined Beck's side, and whatever happened to the uprising, Argon City, and virtually ''every single character in this show'' with the exceptions of Tron, Clu, Quorra, and Flynn.
* ''WesternAnimation/GreenLanternTheAnimatedSeries'' ends with Aya coming to her senses when she accidentally hurts Razer, then reversing her attempt to rewrite the universe and destroying the remaining Manhunter army with a virus that also affects herself, then she disappears into the aether. At the end Razer is convinced that she's still out there somewhere in space and goes off to find her, his hope for doing so causing a Blue Lantern ring to follow him.
* ''WesternAnimation/StarWarsTheCloneWars'': Ahsoka leaving the Jedi Order, but so many plot resolves (i.e. What happens on Mandalore, what did Darth Sidious do to Darth Maul, "Did Palpatine really clone the Zillo Beast?", and "How do Poggle the Lesser and Wat Tambor escape from prison to be in ''Revenge of the Sith''?") were left hanging after the show got axed after season 5 ended.
* ''WesternAnimation/SymBionicTitan'' was cancelled before any plot points could be resolved. Some people say the cancellation was due to lack of toy sales, though co-creator Creator/GenndyTartakovsky later revealed that the cancellation was just as fueled by [[ExecutiveMeddling executives wishing the show to be more like]] ''Franchise/Ben10''.
* While ''WesternAnimation/XMen'' had a definitive finale in the episode "Graduation Day", the series had few unresolved plotlines: Friends Of Humanity organization is still out there and is implied to be even more powerful, an episode with Cannon suggested that shady Government agents will try to manipulate mutants to destroy each other and most importantly [[spoiler: the Apocalypse had returned to plan more evil]].
* ''WesternAnimation/ZorroGenerationZ'' ends on the [[BigBad corrupt mayor]] losing his reelection campaign to a much more competent crime boss who also coopted most of his former henchmen in the process. And to stand against this new, greater better, Zorro and Scarlet Whip reveal their secret identities to each other. Because a second season never happened, the increased threat to the city and our hero was never resolved. Although strangely, the intro sequence that ''was'' made for the second season looks as if they would've gone back on this, showing the former villain a lot as if he'd be the main antagonist again.
* ''WesternAnimation/GaryAndMike'' ended with the duo framed for murder and cornered on a incomplete bridge by the police, Gary's father (whose looking to punish him for destroying the SUV, though that was Mike's doing) and Officer Dick (whose after Mike for sleeping with his daughter and costing him a promotion). With nothing left to lose, the duo decide to recreate ''Film/ThelmaAndLouise'' and drive off the bridge. The screen whitens as they do so and were given a "To Be Continued" but the show was cancelled after that.
* ''WesternAnimation/PlanetSheen'' was quietly canceled following the awkward airing of the 24th episode in February 2013 [[note]]Creator/{{Nickelodeon}} [[ScrewedByTheNetwork gave the series]] TheFireflyEffect after the third episode aired and the abysmal ratings came in[[/note]], leaving the series to end on the sad note of Sheen never finding a way to return to Earth.
* ''WesternAnimation/SamuraiJack'' originally ended with the title character helping a baby, with no resolution on stopping Aku. Originally {{Subverted|Trope}} as creator Creator/GenndyTartakovsky was to have plans to helm the [[WhatCouldHaveBeen now-cancelled]] [[TheMovie movie]]. DoubleSubverted as a fifth season was already completed.
* ''WesternAnimation/{{Metalocalypse}}'' ended on a TV Movie, ''The Doomstar Reqiuem'', with Dethklok finally shedding their selfish ways, saving Toki and apparently on the track to godhood. But Offdensen quits being their manager to become the new head of the Church of the Black Klok, Selectia is still plotting something with his Project Falconback and Murderface was pricked by a "fan"'s spiked braclet during the movie which injects him with something and seemingly will sow discord with the band later. So what happens next? Well your guess is as good as anyone else's since Adult Swim and creator, Brendon Small, got into a disagreement over creative differences, resulting in [=AS=] ultimately cancelling the series. Even despite fan support, [=AS=] refused to budge and Brendon was later quoted stating he was done making music for the series.
* ''Oh No! It's an Alien Invasion'' is about a group of kids battling aliens that have captured and hidden their parents. In the final episode, [[spoiler:just as the kids find where their parents were hidden, TheDragon gets there first and hides them somewhere else]].
* The ''WesternAnimation/{{Fatherhood}}'' episode "The Birds, Bees, and Bindlebeep" ends with Norma announcing to Arthur that she is pregnant with their fourth child and Arthur freaking out about it, because of the show's abrupt cancellation the story was never concluded and the child's gender was never revealed.
* The British adult claymation series ''Crapston Villas'' ended on a cliffhanger as a bus was about to crash into the titular apartment building.
* The tenth season of ''WesternAnimtion/TheSmurfs'' is about a dozen of the main characters lost in time due to magical crystals traveling from time to time. As the show was cancelled after that (generally ill-received) season it ends with it never known whether the Smurfs did return to their original time.

* An old joke around this trope; a man living in an apartment building has fallen into the habit of dropping his shoes on the floor when he gets home and takes them off. This causes his downstairs neighbour to complain about the frequent noise. One evening, the man comes home, takes off one of his shoes and drops it, but then remembers his neighbour's complaint and places the other one quietly on the floor beside the first shoe. Hours later, he's going about his thing when he suddenly hears an anguished cry from downstairs: [[spoiler: "For God's sake, drop the other shoe!"]] Ba-dum-tish.
