* Fans of the original ''LightNovel/HaruhiSuzumiya'' light novels cried foul when the AnachronicOrder of the books was different from that of the show; never mind that it was ''still'' out of order, the climax was ''still'' at the end and it ''still'' worked from a storytelling point of view. Then again, they were also in shock that [[ItsPopularNowItSucks their beloved obscure light novel series was now a]] CashCowFranchise [[ItsPopularNowItSucks loved by millions]].
** That said, if that didn't FOREVER ruin Haruhi, Endless Eight sure as hell did.
** To be fair, the novels, while out of order, finished a story before moving to a different one, while the anime was all over the place.
* [[DarthWiki/RuinedFOREVER This trope]] caused the BrokenBase of ''Anime/NeonGenesisEvangelion'': When it moved into the second half, many of the more traditional shounen fans claimed it was Ruined FOREVER because of being.... ''Neon Genesis Evangelion''. The base broke even further due to ''Anime/EndOfEvangelion'' later, which some saw as an example of a TrollingCreator.
** Fundamentally, ''End of Evangelion'' forms an alternate ending for the series, along with the updated "video & LD versions" of episodes 21 through 24. Fans do exist who would have preferred that NGE ended with its television broadcast of the original ending, some considering the updated ending to be unnecessary retcon that soils interpretation of the show.
** ...and further ruining things is the game ''Neon Genesis Evangelions'' (or NGE2) for {{PlayStation 2}} and PSP. This was released in two iterations during the Aughts and marketed as containing the answers to the show's most niggling secrets. Much of this material has been translated over the years, and there have been no shortage of appreciative fans -- but with that comes a vocal minority crying foul that the game reveals too much and ruins the mystery. (Never mind that with every secret spoiled, many more mysteries have been created.)
** If the [[Anime/RebuildOfEvangelion new Evangelion movies]] (the fan-branded "Rebuild") end up being connected ''in-universe'' to the original Evangelion series, many Eva fans will cry out "RUINED FOREVER" in a singular voice so terrible that it will knock the planet off-axis.
*** . . . And they may awaken their Evas, creating a literal Third Impact all their own.
* At what point was ''ArmoredTrooperVOTOMS'' Ruined Forever for people looking for a hard sci-fi mecha series? Was it Roots of Ambition where Chirico survived a shot in his heart due to Perfect Survivor status? Was it The Shining Heresy where Chirico was BornLucky enough to do a crazy ricochet fluke shot into the Order Buckler's cockpit and destroying Teitania's Auxillary Brain, Was it the newer [=OVAs=] such as Pailsen Files and Phantom Arc for Sunrise copping out on [[{{ConspicuousCG}} dodgy computer-generated ATs]] and it basically amounting to needless padding on Chirico's backstory, Some even claim that VOTOMS wasn't very realistic to begin with when the Quent arc rolled around and TheReveal happened. for bonus points, mention the phrase "Child of God." as that aspect of Chirico's character is a sore spot with many fans.
** Oh hey, ''ArmoredTrooperVOTOMS'' has a new OVA called CASE IRIVINE. Hey the AT's are actually animated this time and there's no Chirico! Wait... Wait! Hold the phone! Why is there [[{{CharClone}} a guy with a mask and a red AT?]] Why are the characters drawn as [[{{Bishonen}} prettyboys]] and not [[{{Gonk}} gruff military guys believable in the role of soldier?]] Why does the combat move as fast as Anime/CodeGeass? Why does one of the characters [[HeyItsThatVoice Sound like Lelouche?]] ''VOTOMS'' is impossible to be taken seriously anymore!"
** Fyana's sidelining and death in Shining Heresy is another sore point with some fans, along with the fact that the plot apparently had to be cut down and rushed from the original OVA outline.
** Ypsilon's backstory in ''The Last Red Shoulder'' is debated, with some feeling it ruined his character in portraying him as a naive child-like man who only became driven to kill Chirico due to Killy and the twins' insistence, rather than him being born that way from the start.
* ''Anime/DigimonFrontier'': What the?! The Digidestined in this series transform into the Digimon?! And there's no real partner dynamic?!
** There was also a ''massive outcry'' at the [[ReplacementScrappy cast reboot]] in ''Anime/DigimonTamers''? Not to mention the fact that [[Anime/DigimonAdventure the original]] was a ShowWithinAShow there.
** [[Anime/DigimonSavers Marcus]] doesn't wear [[GogglesDoNothing GOGGLES?!]] The characters are OLDER than 12?! The animation is more anime-y? [[ArsonMurderAndJaywalking AGUMON'S NOSTRILS ARE FEATURELESS POLKADOTS?!]] Say it isn't so!
** [[http://www.animenewsnetwork.com/news/2010-04-05/new-digital-monsters/digimon-tv-anime-image-posted Another Digimon season this July?]] Yay! But what's this? The [[GogglesDoNothing Goggle boy]] is the only human featured? And why does he look like the love child of Tai and Davis ([[HoYay Dream come true in certain circles]])? The Digimon on the right looks like [[Anime/MonsterRancher Tiger]] and all of the Digimon's designs look like they come from a generic [[{{Bakugan}} Toyetic anime.]] What's a [[{{Mecha}} mecha-looking]] Digimon doing there? And Greymon again?!
** ''DigimonAdventure02'': Yamato and Sora together?!! To war Tai fans! [[DieForOurShip To WAR!!!!!!!111]]
** Many fans dislike ''Anime/DigimonXrosWars'', because the Digimon don't digivolve and mostly combine with others. Even though its nothing new since 02.
* ''Manga/{{Naruto}}'': Most commonly Sasuke [[SpotlightStealingSquad being the focus of an entire arc]] (especially the part about [[spoiler:[[ShockingSwerve Itachi being a good guy]]]]). Honestly, it has such an UnpleasableFanbase you can find someone that thinks the series JumpedTheShark at any moment, usually in the form of "(Character X) [[OutOfFocus hasn't done anything in months]], it's ruined!" Additionally, there's also a segment of the fandom that has said the TimeSkip was when they stopped liking it, [[SelectiveObliviousness even if most of what they're complaining about didn't happen until quite a while after or had been happening for a while before the time skip itself]] and they more or less seem to just be trying to focus their scorn on something important.
** The [[spoiler: instant revival of everyone who died]] during the Invasion of Pain Arc pissed off many fans. Of course, the fans were also pissed when [[spoiler:everyone died]] so now they're thought of as unpleasable.
** The announcement that ''Naruto Shippuden'' would air on Creator/{{Disney XD}} has obviously not been taken well in certain parts of its [[FanDumb fandom]]. Despite the fact that Creator/VizMedia will still be releasing uncut [=DVDs=], so even if it does turn out to be a {{Macekre}} there won't be that much reason to complain. As can be seen with Marvel, just being associated with Disney is prone to bring in the ruins.
** Tobi is really [[spoiler:Uchiha Obito]]? [[TheUntwist WELL I DIDN'T SEE THAT COMING]]! The final battle ''really'' lost its impact at that moment.
** Wait, [[TrollingCreator Kishi]] is [[ShipToShipCombat zig-zagging between Naruto/Hinata and Naruto/Sakura]]? And now [[spoiler: Sasuke wants to become ''HOKAGE''?]]
* The ''Anime/{{Pokemon}}'' anime got this with Misty being PutOnABus and fan backlash against May [[ReplacementScrappy solely for filling the obligatory girl role Misty had]]. There are still some militant fans claiming this long after Dawn took over the girl spot, even though it's been ''years''.
** Any of Ash's female companions seem to spark these responses in general. Dawn gets hate for not only being another Misty replacement, but for replacing ''May'' as well. And then there's Iris, who in turn is hated for replacing Dawn and used as yet another example of the show being ruined.
** The dubbing of the show also got this claim after it went in-house, mainly due to the resulting voice actor switch, with the [[TheOtherDarrin jarring changes made]] to the voices of characters that fans had become adjusted to. That said, it still fits this trope to a "T". But most of the fans really don't even give a damn anymore, since the new voice actors improved over time (for the most part).
** And now for something not related to the voice actors: OMG they changed the "TO BE CONTINUED" text! And the title of the episode was written in English instead of Japanese with English subtitles! So were the credits! The anime is ruined FOREVER!
** Some Team Rocket fans claimed the trio was ruined FOREVER!! when Jessie and James were given black uniforms and a serious promotion, along with a new serious-business attitude. In reality, they were made {{Badass}} and much more awesome, though the change didn't last for the whole arc.
** In fact, the tiniest change to the ''Pokemon'' animé will result in fans complaining that it's Ruined Forever. Ash got dumber? RUINED FOREVER!!! Brock has [[PutOnABus left the show]] even though [[OverusedRunningGag him flirting with girls was only funny the first three times]]? RUINED FOREVER!!!
** Several members of the fandom cried 'RUINED FOREVER" after the One Shot character Tobias defeated Ash with a Latios and a Darkrai. In fact, just the very idea of certain Pokemon being used in the Anime has caused fandom uproar.[[note]]Usually [[OlympusMons Legendaries]], though Dawn getting a Togekiss roused the ire of Misty fans, even those who hated the original Togepi.[[/note]]
** On the other end of the scale, Ash being defeated by Cameron, who's an even bigger Idiot than [[IdiotHero Ash]], is a sore spot in the fandom. The fact that that left the actual champion as TheUnfought didn't help.
** Having the replacement arc for Team Plasma ''follow'' the TournamentArc? Stuffing all your {{Filler}} in the last 5 months of the generation? I'm not too sure about this...
** Once it became apparent that the Mewtwo in ''Anime/PokemonExtremeSpeedGenesectMewtwoAwakens'' was in fact a new character rather than the original Mewtwo, the fandom declared not only that the movie was ruined, but that everything involving the original Mewtwo was somehow retroactively ruined as well. It's also being touted as ''the'' point that the (current) writing staff gave the PeripheryDemographic[[note]]read: anyone who started watching when Misty or May were on the team and is still watching[[/note]] an EyelidPullTaunt using [[FlippingTheBird the middle finger]].
** And in 2014, when the policy on Ash is that he's NotAllowedToGrowUp, we get Serena who, in addition to being the replacement female, is somehow [[RememberTheNewGuy connected to his past]]. Tread lightly writers, [[{{Retcon}} tread]] ''[[FirstGirlAfterAll light]][[ShipToShipCombat ly]]''.
* To expand on that, parts of the online fandom of any given anime tends to say that ''any'' anime that gets [[SubbingVersusDubbing dubbed into English]] (no matter how faithfully), is "ruined", despite the fact that no one's ever going to force them to actually ''listen'' to the English audio.
** Even though the Ghibli dubs are generally respected, there are some so-called "[[FanDumb true fans]]" who insist on hating them simply because they're by Disney, and they object to any change to the dialogue, music, that may have been done to these films, stating that these movies have all been destroyed; an argument which is totally fatuous considering that Miyazaki and Ghibli were both involved with the creation of the dubs. If they don't think their works are ruined, who are such "fans" to say otherwise?
*** Made even more ironic considering Miyazaki himself stated that for quite a few of his characters he was forced into a form of "AccentAdaptation" due to the lack of any dialect he felt fit the characters within the Japanese Language. A prime example he named is the Witch of the Waste in ''Anime/HowlsMovingCastle''.
*** Speaking of that one: Disney let the younger siblings of Miley Cyrus and the Jonas Brothers voice-act Ponyo and Sousuke (respectively) in the English dub of ''Anime/PonyoOnACliffByTheSea''? Cue building nerdrage via PeripheryHatedom by proxy.
** And on the flipside, with the anime industry scrambling to salvage itself and still turn a profit while still trying to license a diverse bunch of shows, several "niche" shows are being released sub-only. You know, the kinds of shows that put even a large studio like Creator/{{Geneon}} out of business because the dub cost so much the show didn't turn a profit. Anime is now ruined FOREVER because the industry is "[[FlippingTheBird discriminating]]" against dub fans. Strangely, nobody thinks the industry is ruined FOREVER because of the ongoing recession.
* The ''Anime/PrettyCure'' fandom is apparently the DistaffCounterpart of the ''Transformers'' fandom or something, judging by the InternetBackdraft that occurs every time the premise of the next series is revealed without fail, complete with one subset that everything needs to go back to the way it was in [[Anime/FutariWaPrettyCure 2004]]. When your fandom complains about ''Anime/FutariWaPrettyCureSplashStar'' for being an AlternateContinuity, then complains about ''[[Anime/YesPrettyCure5 Yes! Pretty Cure 5GoGo!]]'' for ''not'' being an AlternateContinuity. And then you have ''Anime/PrettyCureAllStars New Stage'', due to the fact that the movie focuses more on the original character introduced in the movie and the [[Anime/SmilePrettyCure current]] and [[Anime/SuitePrettyCure previous]] teams than [[Anime/FutariWaPrettyCure the]] [[Anime/FutariWaPrettyCureSplashStar whole]] [[Anime/YesPrettyCure5 seven]] [[Anime/FreshPrettyCure teams]] [[Anime/HeartcatchPrettyCure combined]]. Sheesh...
** And now we have confirmation that Creator/SabanBrands owns the distribution rights to the series...
* It appears to be very common in mainstream mecha anime. Fans have found something to complain about ''in every single episode'' for ''Anime/CodeGeass'', ''MacrossFrontier'', and ''{{Gundam 00}}'', with the amount of ruin escalating the higher the episode count is. ''Anime/CodeGeass R2'' in particular has the series FOREVER at least once per episode, according to some {{Fan Dumb}}s.
* ''Anime/TengenToppaGurrenLagann'': Yes, even this! [[spoiler:Kamina's death is proclaimed this by some]]. This sentiment usually disappears after they see the rest of the series, and some have since even considered it [[GrowingTheBeard the point after which the show got better]].
* Many ''Manga/FruitsBasket'' fans cried this when it was revealed that [[spoiler:Akito is female]], which [[ShipSinking sunk ships]] everywhere and created a generally hilarious explosion because we all know that HetIsEw and they totally ruined the character for ever and ever.
* "What's this, the upcoming ''MagicalGirlLyricalNanoha'' sequel manga will have a male protagonist? [[HetIsEw OUR LESBIAN DREAMS!!!!]] [[BigNo NOOOOOOOOOOOOOOO!!!!!!]]" Note that the new protagonist has his ''own'' love interests, so he can't interfere with the main characters from the previous series anyway...
** Erstwhile members of the [[YuriFan Lily Appreciation Society]] need not abandon ''all'' hope; a girl named Lily has been named as co-protagonist. [[MeaningfulName Coincidence?]]
** Unfortunately, Touma has a working relationship with Subaru...oh shit...
** Some argue that ''Anime/StrikerS'' ruined the series forever, particularly by [[DemotedToExtra drastically reducing certain characters' screentime]], [[PutOnABus if not writing them out entirely]] (Particularly [[RomanticRunnerUp Yuuno]]).
** It should also be noted that fans of the [[RomanticTwoGirlFriendship Nanoha/Fate pairing]] who RAGE at having a male protagonist in the ''Force'' manga actually ''adore'' and ''worship'' [=StrikerS=] for making the heroines [[RomanticTwoGirlFriendship share a bed]], have six-year-old [[CloneJesus Vivio]] [[HasTwoMommies call both of them 'mama']] and, thanks to the [[AudioAdaptation sound stages]], be called 'The Takamachi Family'. Not to mention that they are very glad about the [[PutOnABus the almost-disappearance]] of [[RomanticRunnerUp Yuuno]].
** "''FORCE'' is no longer a magical girl show! RAEG!"
** [[BadassDecay What have they done to]] [[spoiler:Signum and Hayate]]!? God damn you, this is no longer Nanoha!
* Fans have different opinions on where this happened in ''Manga/{{Bleach}}''.
## [[spoiler:When [[AnIcePerson Hitsugaya]] (presumably) beat Halibel]] there was a sudden influx of "Bleach is ta lose!!11one!" [[spoiler:When it was revealed that he hadn't even scratched her, very few of those who declared the series ruined came forward to retract their previous assessment.]] Particularly sad considering the lack of genre savviness of these viewers; when has trapping an opponent in ice ever worked? (except in Fairy Tail)
## Since the start of the Soul Society arc.
## Since the END of the Soul Society arc, and into the filler Bount Arc that seemed to go on forever.
## Almost any point after the start of Ichigo vs. Ulquiorra.
** Special mention should probably also go to [[spoiler:Yammy's {{Reveal}} as the 0 Espada]], which tended to be viewed as a) wall-bangingly [[AssPull stupid]], b) hilarious, c) [[CrowningMomentOfAwesome awesome]], or d) some combination of the above.
** Many readers following the chapter releases online actually embraced the whole thing and started to enjoy the many inventive ways the author can come up with to "ruin" his manga. The most ridiculous the development, the better! Kubo himself stated that he really loves designing characters and admits to creating new ones as a way to get himself out of writer's block.
** This has not been stressed enough. Every time something happens in Bleach, it's ruined forever. Starrk didn't kill a billion Captains? He was pointless. Ulquiorra is popular? He's being milked. People expected more of the Vasto Lordes? Kubo overhyped them. The Fake Karakura Town Arc? Too much fighting, not enough character development. The beginning of the Lost Agent Arc? This is so slow it's worse than filler! Kyoraku didn't reveal his Bankai & that's terrible, but the series should have ended anyway. The point here is that the fanbase is unpleasable.
** There was also a case of this during the Deicide in which the "fans" had a problem with, wait for it..., the name; complaining endlessly that Tite is an idiot who couldn't spell the word decide right. Said "fans" tended to ignore the possibility that Deicide could possibly be a word itself and didn't even bother to do a simple Google search to do the research. Like the above example very few retracted their statements. It pains this troper how little common sense and basic dignity is left in the Bleach Fandom nowadays, though granted, of cource, that these are only the vocal minority.
** This has perhaps become even more pronounced in the last arc due to such revelations as [[spoiler: Masaki Kurosaki being a Quincy, Retsu Unohana being revealed as an unrepentent bloodthirsty psychopath who dies just for the sake of making Kenpachi Zaraki stronger, and the true nature of Zangetsu.]] Because these developments fundamentally alter perception of the characters, some of the fans who dislike them say that their enjoyment of the earlier parts of the series has been irrevocably tainted. And that's not getting into the ever present debates on whether these developments make sense, could have used a better build up or are just straight up [[AssPull Ass Pulls]].
* Some people say that [[spoiler:L's death]] did this to ''Manga/DeathNote'', and that [[spoiler:Light's death at the end of the series]] ruined it even more.
* Some sections of the ''VisualNovel/UminekoNoNakuKoroNi'' fanbase tend to think every new and irritating bit in TheAnimeOfTheGame (which there is admittedly quite a lot of) has Ruined the series FOREVER. Particularly cutting out all the real-world parts of [=EP4=] after [[spoiler:George and Jessica kill each other]] to give more time to the Meta-World sequences and backstory for a somewhat CreatorsPet-ified Ange.
* A second season for the anime ''Manga/BlackButler'' was announced... featuring an original new protagonist and Butler not from the previous season or manga, and not Ciel and Sebastian. Cue the wailing of thousands of yaoi fangirls around the internet. Which, as it later turned out, was A-1 Pictures just trolling the fandom.
* ''Manga/OnePiece'' started getting these accusations once [[spoiler: Portgas D. Ace bit the dust, breaking the tradition of not killing named characters, except in flashbacks, that was maintained for 13 years of publication.]]
** Named characters '''have''' died, there had just been too many Disney Deaths.
** And then, after [[spoiler: there was confirmation of a TimeSkip happening, it started rising again.]]
** Some people complained about Hancock falling in love with Luffy because it would ruin the series being strictly NoHuggingNoKissing. Thankfully, this was averted.
* Oh cool, [[SarcasmMode FINALLY]] there will be a [=LatAm=] dub for ''DragonBallZKai''. Oh wait... there were economic issues? Half of the original [[VoiceActor VAs]] refused to dub? [[TheyChangedItNowItSucks THEY WERE REPLACED BY COMPLETE STRANGERS?! INCLUDING THE SINGER?!!]]
* Parodied in ''Anime/DarkerThanBlack'' with Kiko and her otaku friend. After months of giddy anticipation over the next release of their favorite anime, they storm out in anger over how it's Ruined FOREVER, and Kiko ''will not let the director get away with this''!
* ''Anime/MobileSuitGundamZZ'' was [[WhamEpisode such a shift in demeanor]] from the much darker ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'' that much of the fandom [[FanonDisContinuity would prefer not to think it happened.]]
** Unfortunately, SOME people think that anything that is not UC is crud and therefore thinks that they ruined Gundam forever.
** ''MobileSuitGundamWing'' was this for [[FanDumb "veteran" Gundam fans]] (i.e. UC elitists) when it came to the US. Holy crap, a ''Gundam'' series with pretty boys in mobile suits[[note]]As if that has never happened in ''Gundam'' before[[/note]], all talking about war and peace and nonsensical political intrigue and shit[[note]]As if that ''also'' has never happened in ''Gundam'' before[[/note]]!? And it's ''not'' [[AndThatsTerrible set in the Universal Century nor directed by Tomino!?]] [[BerserkButton And worse, people actually LIKE IT!!?]] Char help us!!
** Much to the continued amusement of this troper, ''TurnAGundam'' was considered ''Gundam'''s embodiment of this trope back around the turn (pardon the expression) of the century. A ''Gundam'' series that focuses on character development and slice of life elements as opposed to giant robots fighting each other and people dying in gruesome and unlikely ways!? Say it isn't so!
** According to some fans, ''MobileSuitGundamSEEDDestiny'' utterly destroyed the ''MobileSuitGundamSEED'' fandom. So much so, that these fans will go so far as to pretend it didn't even happen lest ''SEED'''s reputation not be salvaged.
** Depending on who you ask, ''00'' was either ruined forever in its first season (''FullMetalPanic'' with Gundams), in its second season (the ''Zeta Gundam'' rehash) or in its movie (the bastard child of ''Char's Counterattack'' and ''StarTrekFirstContact''). To summarize, ''00'' was ruined forever because it either 1.) diverted from traditional ''Gundam'' storytelling, 2.) reverted to traditional ''Gundam'' storytelling or 3.) [[ArsonMurderAndJaywalking was invaded by an army of T-1000s]]. And then there's the crowd who found ''00'''s writing shoddy throughout...
** You thought the fans' reactions to ''Anime/MobileSuitGundamZZ'' were bad? Well, it doesn't even compare to how much flak ''MobileSuitGundamAGE'' is receiving. Universal Century and [[Anime/MobileSuitGundam00 Anno Domini]] fans seem to forget, however, that Tomino [[FanDumb specifically made Gundam for the younger generations.]]
*** Tomino only made the original series for younger generations (a la kids), whereas every other series that followed (including ''ZZ'' surprisingly enough) was definitely marketed toward the young adult and above crowd. Just compare how people died in ''MobileSuitGundam'' to how people died in ''Zeta Gundam'', the latter (much darker) half of ''ZZ'', ''MobileSuitGundamCharsCounterattack'', ''MobileSuitGundamF91'' and ''MobileSuitVictoryGundam''. The latter line of ''Gundam'' series would be pure NightmareFuel for kids.
** Even for the fans, ''GundamAGE'''s Third Generation ruined the series forever thanks to the inconsistent plot and the poor attempt to deconstruct the TechnicalPacifist trope. [[SarcasmMode Thank you very much, Vagans and Kio Asuno.]]
* Wait, Creator/SteveBlum ''isn't'' reprising his role as the title character in the ''[[Anime/{{Wolverine}} anime adaption of Wolverine]]''. Booooooo Marvel and G4!! '''RUINED FOREVER!'''
** Although we got [[Series/{{Heroes}} Peter Petrelli]] voicing Wolverine instead.
** Heck, the ''entire idea'' of Marvel Anime (having popular Marvel superheroes in anime style made by Creator/{{Madhouse}}) may be seen as '''RUINED FOREVER''' by many anime and Marvel fans alike, mainly because having popular American superheroes in Japanese anime style is seen not to fit well with each other. Of course, the reception of the Marvel anime idea received mixed reviews from fans and critics alike.
* Woohoo! Creator/BandaiEntertainment licensed ''VideoGame/TalesOfTheAbyss'' anime for U.S. release, wait...'''sub-only'''. [[PunctuatedForEmphasis WHAT! THE! MOTHER! FUCK! BANDAI!]] Why the fuck did you went for a sub-only release when the video game version had an English dub?!?!!
* After seeing just ONE episode of ''VisualNovel/HigurashiNoNakuKoroNi'' Kira (the newest OVA), many of the fans are saying this.
** The episode in question was about 90% sexual fanservice and isn't even canon.
* Many people complain over the Viz re-releases of ''Manga/PokemonSpecial'' for various reasons, the most legitimate complaint being that there seem to be [[NoExportForYou no plans to release the third gen story arcs]] until/unless the Ruby/Sapphire remakes come out, leaving out about 15 volumes worth of material out that will inevitably cause massive plot holes and spoilers in the currently on-going Diamond/Pearl arc.
** The Ruby/Sapphire chapter is finally released, but the above still applies as it'll never catch up to prevent the spoilers.
* It doesn't matter how many years have passed, several fans of ''DragonBall'' feel the series lost it with the switch to ''DragonBallZ'' and the more sci-fi and less comedic emphasis, even though in the latter's case the humor was already being toned down a little by the time Piccolo first showed up.
** Don't even mention ''DragonBallGT'' fans. They will instantly bring up the idea that ''GT'' was not canon since Akira Toriyama did not involve in the development. Their reasons being Goku became a OneManArmy and MartyStu, and other major characters in the previous series existed to be kidnapped, brainwashed, turned into punching bags, or even killed off.
** The Buu Saga is this for many fans with its overall change in tone from dark storylines to focus more on humor and, to the hardcore Gohan fans, its treatment of him from the main character to [[DemotedToExtra supporting role]].
* Don't ask ''{{VideoGame/Medabots}}'' fans what they think of Spirits (The second series), there's better ways of committing SuicideByCop
* Apparently Season 2 of ''Anime/TheMysteriousCitiesOfGold'' is ruined forever because [[http://www.youtube.com/watch?v=Ly1hQrGlaoU they used CGI to animate it]], [[http://www.youtube.com/watch?v=WI1JTLkSZr0 instead of using the classic style]]. Never mind the fact that they managed to find the majority of the original voice actors from the original, that they are able to do a "season 2" with the original premise, instead of doing a complete reboot like many TheEighties cartoons have got (you know, like ''WesternAnimation/ThunderCats'', ''Anime/{{Voltron}}'', ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'', ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'', they were able to keep the same musical atmosphere of the show, except for updating the instruments and cleaning up the background, and that everyone looks almost virtually like they did in 1982.
* Quite a few fans called this when ''Anime/SwordArtOnline'' moved onto the [=ALFheim=] arc. First off, it killed off what would've been a great (and [[TearJerker/SwordArtOnline emotional]]) conclusion to the series. Then, Asuna became a DamselInDistress and AdaptationDistillation removed any evidence that Liz, Silica, Agil and Klein were also in the game. They're instead pushed aside for Sugu and her feelings for her "brother" Kazuto/Kirito. When Episode 21 hit, the arrival of TentacleRope had the fanbase screaming and Episode 24's AttemptedRape of Asuna in front of Kirito sent most who had stuck with the show until that point nuclear.
* FUNimation's dub of ''AxisPowersHetalia'' quickly resulted in this reception. Was it the RatedMForMoney changes that made it more like it was trying ''too'' hard to be offensive and ape South Park? Was it the fact that the characters were cast with ridiculous accents? Or that Frontier Works mandated that the English translators use "Britain" for the England/UK character? These were a few reasons given, among others, in the huge uproar.
** The film of the anime, "Paint it White", earned very negative reactions due to Studio Deen stuffing up the running time with random clips from the anime inserted in between actual plot moments. The DVD version featured a "Skip Play" alternative cut with the clips taken out, although the movie is very short without them.
* Many members of the ''Anime/PuellaMagiMadokaMagica'' fanbase expressed dismay when [[Anime/PuellaMagiMadokaMagicaTheMovieRebellion the third film]] was released, due to [[FaceHeelTurn a certain character's actions]], regarding them as out-of-character moment [[OOCIsSeriousBusiness which causes every established moral and theme in the main series to be destroyed.]] Whether or not these criticisms are justified is up to the viewer. One thing that has managed to lessen the rage is a popular theory that said actions are the start of a ZeroApprovalGambit. Whether that plan was well thought out or not is a different story entirely.
* The dub used "OMNI-DIRECTIONAL GEAR" instead of [[Manga/AttackOnTitan "3-D MANEUVER GEAR"?]] RUINED FOREVER!!!1
* In ''Anime/YuGiOh5Ds'', many fans assumed for a long time that BigBad Z-One was actually Yusei, from the future. What happened when his true identity as an imposter was revealed? Pure rage, at least from American fans. '''"Sacrilege! Ruined forever!"''' (Of course, the thing is, no character on the show or any of the show's writers had ever actually made the claim even once up to then that he was Yusei. Fans had just assumed, like the case with Bruno, that it was an badly-kept secret that was ''intentionally'' badly kept.) What the FanDumb fans might as well have said was, "We don't care how often writers do it, how ''dare'' you lead us on with a red herring and then give us an ending that surprised us?" and "Why should the series have a happy ending where [[StatusQuoIsGod the status quo is preserved]] and the hero remains heroic?" and "How could you think of [[ItsAllAboutMe making the canon source conflict with our fanfics?]]" And so on. These fans never assumed that the creators were going for the ending they didn't expect.
