* AcceptableTargets:
** The [[UsefulNotes/NationalFootballLeague Green Bay Packers]]. The shows' creators were all fans of the Minnesota Vikings, sworn enemies of the Packers.
** Wisconsin in general, despite (because of?) both Joel Hodgson and Michael J. Nelson having grown up there.
** Any film or scene set in Chicago will inevitably have a reference to the Cubs losing.
*** Of course, one realizes that the show originally went off the air almost twenty years before the Cubs finally clinched the 2016 World Series.
** In the movies he appears in, Joe Don Baker.
--->'''Crow''' (''as Joe Don Baker's name appears on-screen''): Ooh, I wish I was illiterate so I wouldn't have to read that.
** Not to mention, "ROSS HAGEN?!?!"
** Sandy Frank. To be fair, he IS the source of all their pain.
*** Coleman Francis as well. Really, ''any'' of the show's repeat offenders get this treatment.
** Crew members with old-fashioned, pretentiously aristocratic-sounding names always get a share of this. "Oh, is the great ''Hollingsworth Morse'' going to direct?"
** Japan. Especially in ''Film/InvasionOfTheNeptuneMen'' where the movies use of wartime bombing footage coupled with the abysmal quality made them particularly vicious in their bashing.
** Canada. Especially in The ''Final Sacrifice'' and ''Zombie Nightmare''.
** Maltese men in the episode ''Final Justice'', at least to Crow T Robot.
** Britain in ''Gorgo'', ''The Deadly Bees'' and any other movie set in the UK.
** Long story short: There were definitely lines of good taste and class that they wouldn't cross, but generally speaking, if they could get a joke out of something they were most likely going to.
* AlternativeCharacterInterpretation:
** Joel was a lot more frustrated with being in outer space during the KTMA era and season 1. Did the situation grow on him, or was he slowly ConditionedToAcceptHorror? The same could be assumed of Mike. During his first couple seasons as host, he was often seen trying to escape the satellite, but he gave up by around Season 7. In Season 9's "Quest of the Delta Knights", Pearl gets ''infuriated'' when she sees Mike acting too accepting about being held captive in space.
** The 2017 revival gives absolutely no indication of why the Bots are back on the satellite, causing some warring fan theories about why they came back (the most popular being that they got homesick for the only home they'd ever known, and just went along with it when they suddenly got another human to watch movies with), or even that they're simply duplicates while the originals are still right where we last saw them.
* AwesomeMusic: Season 11's orchestrated rearrangement of the show's classic credits theme ''Mighty Science Theater'' is beautifully nostalgic. It's hard not to get goosebumps listening to it.
* TheBechdelTest: One avid fan ran the Bechdel Test on [[http://sittingduck1313.livejournal.com/501902.html most episodes]].
** In-universe, the very test was briefly referenced in season 11's third episode ''The Time Travelers''.
* BigLippedAlligatorMoment:
** Valeria (from the movie ''Film/RobotHolocaust'') appearing on the Viewscreen in ep. 201 ''Rocketship X-M'', for seemingly no reason. Joel and the robots seem just as puzzled by her appearance as the viewers. After Valeria leaves, the incident isn't brought up again.
** In ''[[Recap/MysteryScienceTheater3000S02E05RocketAttackUSA Rocket Attack USA]]'', the crew's reaction to the sudden appearance of the blind man who [[DullSurprise rather flatly says "Help me"]] resulted in the scene becoming the show's first [[TheStinger stinger]].
---> '''Tom Servo''': Lucky one. He didn't have to see any of this!
** Crow, in particular, has issues with the movie showing some rather casual reactions to the pending apocalypse.
---> '''Crow''': Cut to New York, where Art Metrano and Harry Connick eat pizza and buy ties for their stupid girlfriends, and Harry Truman gets off a plane by the sewage dump and then a blind guy goes by and says "Help me." ''WHAT THE HELL WAS '''THAT''' SUPPOSED TO BE?''
** In ''First Spaceship On Venus'', Tom and Crow have an encounter with an angry gorilla. It isn't really in context with anything and not even Joel believes that it happened.
** The infamous "Joey the Lemur" sketch, where Joel flings around a lemur puppet and tries to sing a song about it. He gives it a tough guy voice, a rude attitude, and flubs every single line. Also, there were no lemurs in the movie.
*** Subverted, when Joey makes a comeback in "Last of the Wild Horses", much to Tom Servo and Gypsy's horror.
** Crow's dark counterpart Timmy in ''Fire Maidens from Outer Space'', especially when he pops up in the theater.
** A host segment from ''Teenagers from Outer Space'': a rogue spaceship makes contact with the SOL. On the Hexfield, a silent human skeleton attempts to wave, collapses in a heap, then leaves. Even Joel and the Bots are baffled and write off the entire encounter as "lame".
* BetterOnDVD: TheMovie now has the deleted scenes, and deleted theater segments! Fans are already getting to work on a fan edit.
* BrainBleach. What do you expect from being forced to watch bad movies? Check the Trope entry for a few examples.
** It's worth mentioning that it's the only TV show with its own ''folder'' under BrainBleach. One must wonder about the fans...
* BrokenBase: A massive uproar occurred when Mike replaced Joel as host mid-season-five, resulting in a FlameWar so bad that it eventually degenerated into personal attacks and pulled entire web communities apart. For years afterward the subject was banned on multiple fan sites, though in the later days of the fights there were more than a few {{troll}}s fanning the flames (Joel Hodgson himself admitted years later that [[TrollingCreator he'd been one of them]], not really understanding how serious it was). These days, while fans disagree about who was better (and most admit that it really just comes down to personal preference), most find they generally liked both. Jonah Ray joked that an advantage of being the new host was that [[{{SelfDeprecation}} he could unite the Mike and Joel fans into hating a common enemy]].
** This has arguably continued into the principals' post-''MST'' projects, with fans debating the merits of (Joel-led) ''WebVideo/CinematicTitanic'' vs. (Mike-led) ''Podcast/RiffTrax''.
*** Mike Nelson, at one point, proposed to parody the Joel vs. Mike debate by setting up a mock rivalry between Rifftrax and Cinematic Titanic, but Joel Hodgson (who is, incidentally, still a close friend of Mike's to this day) turned down the offer.
*** Joel's return in the {{Soultaker}} episode pokes fun at the fan rivalry. Mike is somewhat jealous of Joel's new life as the manager of a hot fish shop, but the bots remind Mike not to compare himself. "It ain't healthy."
** Also notable is that the change was largely just cosmetic: Mike had been the show's head writer since the first season.
** The Sci Fi Channel era was this as there were certain issues such as how in Season 8 they tried to retool the series by adding in a lot of Sci Fi HighFantasy subplots in the Host Segments. Not too mention on how the actual riffs themselves have gone considerably meaner and darker. This is especially apparent when the riffs target [[AcceptableEthnicTargets the movie's country of origin]] such as England, Canada and particularly Japan. (Some even accused the show of being racist.) However Best Brains have tried resolving some of these issues as during Season 9, the series returned to being set back on Modern Earth. And as for the latter they have occasionally tried to comment on that like Servo dressed up as a Mountie and doing a skit about respecting Canada in "The Final Sacrifice" episode or having Crow forget why he was mocking Maltese men in "Final Justice". Though that being said the last 3 seasons still had plenty of highly renowned episodes such as "Hobgoblins", "Screaming Skull" and "Space Mutiny". Plenty of the viewers from the Comedy Central era were still fond of the show and there were also plenty of fans who became fans during the Sci Fi Channel era.
** Is is okay to skip host segments while watching full movies? This is still a point of contention among some fans.
** Their riffs of movies from otherwise popular franchises tends to get rather heated. Their riffs of ''Franchise/{{Godzilla}}'' movies, in particular, can get rather heated from vehement defenders of the movies they riff to those who, even though they're fans of the franchise, feel those movies in particular still deserved to be riffed.
** The casting for the 2017 revival, with many fans taking issue with the show now having a bunch of big names rather than the nobodies that gave the original a good deal of its charm. Others counter that they'd be under an insane amount of scrutiny from long time fans, so it was best to not subject any new unknown actors to that and get people who could easily weather it.
** Other fans wonder why they'd even ''need'' a reboot when Nelson, Murphy and Corbett are still in top form on WebOriginal/{{Rifftrax}}, albeit sans silhouettes, and thanks to the audio commentary format, have riffed blockbuster films and franchises (most notably ''Franchise/StarWars'' and ''Franchise/{{Twilight}}''.)
** Upon its release, the revival also got some heat for too often breaking the illusion that we were watching these guys coming up with jokes as they watched a movie. The timing of the riffs is often a little too perfect, making it obvious they were written by someone with advance knowledge of the movie.
** The LullDestruction style of riffing has also gotten mixed reactions from fans. Most hate it, because it gives the impression they're afraid of losing the interest of younger fans if there's ''any'' silent moments, while others are okay with the more rapid-fire pace of riffing because it means [[RewatchBonus more jokes to catch on later viewings.]]
* CounterpartComparison: Tom and Crow to Radio and Lampy from ''WesternAnimation/TheBraveLittleToaster'', whom they distantly resemble. Like Radio, Tom is a small, red machine with [[EyelessFace no visible eyes]] who has a lot of energy and is a bit of a MotorMouth. Crow and Lampy are both tall, golden coloured to varying degrees, both have close-set yellow eyes and are both likable and childlike and aren't afraid to speak their minds. The difference between both pairs is that Tom and Crow are much smarter,
* CrackIsCheaper: Given the way they're released (four episodes at a time, about forty dollars a set) and how many of the older Rhino sets and single releases are out of print, trying to collect all the commercial DVD releases is a nightmare.
** A set of four is usually around $60, a single episode is about $15. Assuming all 198 episodes are released, plus the movie and the home-game episode, the entire series would cost around... sigh... [[ContrivedCoincidence $3000]].
*** At last, we know the ''real'' reason the show's name ends in '3000'!
** Notably, the episodes sold on the [=RiffTrax=] webpage are priced at a more reasonable $10 per pop.
* CriticalResearchFailure: Many of the movies the crew riffs on are guilty of this, but it's also invoked intentionally for comedic effect during some of the host segments.
** In Tom Servo's planetarium show in the prologue for the ''Skydivers'' episode, he refers to the speed of light as "well over five hundred miles an hour" (which is technically true but also incredibly imprecise: the speed of light is 670.6 ''million'' miles per hour) and calls UsefulNotes/{{Mars}} "the brightest star in our galaxy". Needless to say, Crow and Mike can't resist derailing the show.
** During Crow's Public Service Announcement on how to treat women, he treats women as if they're a cryptozoological phenomenon, like Bigfoot.
*** ...complete with a grainy, black-and-white photo of a fur coat wearing lady that looks like a frame from the [[http://en.wikipedia.org/wiki/Patterson-Gimlin_film Patterson-Gimlin bigfoot film.]]
*** When Mike points out that Crow knows Pearl, he quickly amends his conspiracy to state, yeah, sure, ''one'' woman exists, but do they ''all'' exist?
* CrowningMomentOfFunny: So many that the show has its [[Funny/MysteryScienceTheater3000 own page]].
* CrowningMusicOfAwesome:
** The Main Theme, the Tibby song from {{Gamera}}, and [[Film/SantaClausConquersTheMartians A Patrick Swayze Christmas]]
** While there are enough songs to warrant its own page, special mention is deserved for the [[http://www.youtube.com/watch?v=Ree220FiOEg United Servo Academy Men's Chorus Hymn]]. Why? Well, the combination of hilarity and soul lifting beauty earned this song at last count 578 'likes' and only 3 'dislikes'. Have fun.
** What happens when you stretch the [=MST3K=] End Credits by 800%? [[https://soundcloud.com/triple_sss/mst3k-end-theme-stretched-out-800-percent Something amazing.]]
*** The end credits themselves, called "Mighty Science Theater" is just that...pretty damn mighty and cool to boot!
*** The [[https://www.youtube.com/watch?v=65Nb73C0Tco 2017 rearrangement of "Mighty Science Theater"]] is preformed by an orchestra, which makes it no less awesome than the original.
** From the revival season: Kinga's duet with [[spoiler: ''Neil Patrick Harris'']] is both this and a CrowningMomentOfAwesome.
* CultClassic
* EarWorm: The theme song in every incarnation.
** ''Watermelon Man...''
** "It's an areological, autoerotical, [[http://www.youtube.com/watch?v=_ePusmtf1IQ toobular boobular joy]]! An exposularegional batchical-pouchular fun for girl and boy!"
** "Idiot control, now...."
** "Oh, let's have a Creator/PatrickSwayze Christmas this year..."
** "I'm gonna be a failure just like you, dad!" "Like me?" "That's right! I'm gonna be a failure ''just like yoooooooou!''"
** "Every country/Has a monster/They're afraid of/In their nation..."
** The jazz/ska covers of songs featured on the original series are pretty damn catchy on their own.
* EnsembleDarkhorse: He only appeared for four episodes, but Peanut was instantly adopted by the fans - and by Mike's relatives, it seems.
** [[Film/ManosTheHandsOfFate Torgo]], especially Mike's humorous portrayal of the character.
** Jerry and Sylvia, the [[Film/TheMolePeople Mole People]] who worked as lackeys in Deep 13. (Oddly, because ''Film/TheMolePeople'' wouldn't be riffed til the Sci-Fi years.)
* EvilIsSexy: Kinga Forrester, the MadScientistsBeautifulDaughter.
* FandomRivalry: Joel fans vs Mike fans, which was pretty much ''the'' debate topic back when the Internet was young (well, besides "[[Franchise/StarTrek Kirk vs Picard]]", of course).
* FanNickname: [[strike:Chastain]] Justine
* {{Fanon}}: Many online sources contend that Joel Hodgson pulled an all-nighter finishing the robots before the first episode, and that this is the source of his on-screen character's sleepy-eyed, laid-back persona. All-nighter notwithstanding, Joel's relaxed attitude was a holdover from his stand-up/prop comedy act prior to [=MST3K=]. [[http://www.youtube.com/watch?v=7EQI9xS2ltI Evidence abounds]] on Website/YouTube.
* FoeYay: Mike and Pearl could get very friendly when she wasn't trying to kill him...
--> '''Mike''' ''(over beers):'' So, Pearl... how come you're so evil?
--> '''Pearl''' ''(considering the question thoughtfully):'' Hm... I'm filled with hate... I'm not sure if that helps.
** Pearl and Crow are close friends, though Pearl refers to him as "Art". (See IAmNotShazam)
* FunnyAneurysmMoment:
** During the host segment for ''Film/GirlInGoldBoots'' where Crow strips, one of Tom's reactions to Mike's horror is to call him "Mike '[[WarOnTerror Taliban]]' Nelson."
*** The Taliban, prior to 2001, were an obscure group on the State Department's "hostile but ineffective" crazies list - getting the gag was a GeniusBonus at that time. The Taliban were simply thought of as a RealLife version of the town leaders from ''{{Footloose}}''. ("I can't believe it, but I'm starting to agree with the Taliban Militia. Dancing should ''not'' be allowed.")
** There are numerous school shooting jokes in "The Home Economics Story".
** This line from the otherwise hilarious classic, ''Hike Up Your Pants'' song, "...Yank your trousers higher than Corey Haim, oh wow..."
** The quip in 'Prince Of Space' "Woody Allen asked me out", then a reference to Woody Allen's marriage to his stepdaughter Soon-Yi took a much darker tone after his stepdaughter Dylan accused him of having molested her.
*** Same goes for the joke "The Woody Allen Story!" when the title screen of "A Date With Your Family" comes up.
** In the ''Film/OverdrawnAtTheMemoryBank'' episode, when in the movie Fingal bemoans people who "Never saw a cinema in their lives", Crow snarks: "Never saw a Creator/ChrisFarley movie. Philistines!" Farley died 12 days after the episode aired.
** The release of ''Film/{{Logan}}'' a couple months before the revival series rather kills a joke in ''Avalanche'', that [[spoiler:one of the characters is harder to kill than Wolverine]].
* GeniusBonus: How many other comedy shows make casual references to Bedřich Smetana or Margaret Chase Smith?
** [[Film/ManosTheHandsOfFate Torgo]] [[Literature/LordOfTheRings the White]] was this at the time - in 1995 when Frank Conniff left the show, the announcement of the Creator/PeterJackson [[Film/LordOfTheRings adaptation of the classic]] {{Doorstopper}} novel was still four years away.
** [[Creator/{{Aristophanes}} Bre-ke-ke-kex, co-ax, co-ax]].
** During ''Film/DevilFish'': Mike makes several [[DoubleEntendre Double Entrendres]] involving outboard motors, making reference to the Evinrude brand (observing Peter "grabbing at his own Evinrude", etc.). Not only is Evinrude a vaguely naughty-sounding word already, it's a substitution for another famous outboard motor manufacturer/dirty word: Johnson.
** In the ''Film/AgentForHARM'' episode, Mike is put on trial for [[MikeNelsonDestroyerOfWorlds blowing up multiple planets]], and during the trial Professor Bobo manages to destroy Observer's testimony thanks to his encyclopedic knowledge of pies... or so it would seem to most people. The real joke is only noticable to people who know a thing or two about baking: Observer's entire testimony is a litany of pie-making Dont's and the mistake Bobo called him on was the most ''minor'' of them.
* GrowingTheBeard: The cast and crew themselves have acknowledged the uneven quality of early episodes. This was largely because the on-screen talent were watching the movie for the first time, and many of their riffs were being made up as they watched. By season three, they had a more organized approach where the writers watch the movie in its entirety before approving it for [=MSTing=], then watched it a second time to write the jokes[[note]] part of the reason for this was season two's ''Film/TheSidehackers'', which included a graphic rape/murder scene that the writers first saw during their joke-writing session because nobody in the crew had watched the film in its entirety[[/note]], and a third time to film the episode. Season three's ''Film/PodPeople'' is frequently cited as the first truly great episode.
** Also a literal version, as Joel grows some chin whiskers late in season two. At the same time, the quality of the episodes was increasing rapidly. It's an aversion because the whiskers disappeared by season three, yet the quality kept improving.
* HarsherInHindsight: As if the RealitySubtext with Crow's script ordeals in ''Film/TheIncredibleMeltingMan'' episode wasn't enough, it gains yet another dimension if you think of what Bill Corbett (who later voiced Crow) went through with his pet project ''[[MeetDave Starship Dave]]''
* HilariousInHindsight: So many that it has [[HilariousInHindsight/MysteryScienceTheater3000 its own page]].
* HoYay: Tom's got a roll of singles as thick as a pork roast for stripper Crow in the host part of the [[Recap/MysteryScienceTheater3000S10E02TheGirlInGoldBoots Girl In Gold Boots]] episode.
** The bots loved to pick on Mike, especially in the Sci-Fi Channel episodes, even going as far as to having mixed {{Tsundere}} traits towards him.
** Occasionally we get a bit of this with Dr. Forrester and TV's Frank. (There's at least one sketch -- the infamous "let's call the Mads" host segment -- which ''blatantly'' implies that neither of them are straight.)
-->'''Dr. Forrester:''' Oh my God -- Frank, switch on the game! ''Switch on the game!!''
*** In the episode where Dr. F and [[WholesomeCrossdresser Auntie McFrank]] open a Bed and Breakfast, we get this exchange:
--->'''Kevin ''([[TheDanza Kevin Murphy]])'':''' So, Clay? You and Auntie [=McFrank=]? Are you...?
--->'''Dr. Forrester:'''...Partners?...Yes, we're...oh, look! Here comes breakfast!
** Dr. Forrester is also a ''little'' too affectionate towards Joel, giving him {{Affectionate Nickname}}s and whatnot.
** During one of the dance scenes in "Catalina Caper", Tom riffs "Girls just can't resist the frockling vibes of a hot guy... and neither can I!"
* ILikedItBetterWhenItSucked: Quite a few fans responded to the first looks at the 2017 revival that it just felt wrong for the show to have a crystal clear image and more articulated puppets, after the low tech and homemade feel of the classic version. It's mostly a result of camera and puppetry technology coming a long way and being much cheaper than it was twenty years ago (you can thank Jim Henson for Tom and Crow's new radio-controlled heads). Though they do like that at least all the exterior shots retain the endearingly clunky nature of the original.
* InformedRealLifeFame: Frank being referred to as "TV's Frank" as if to suggest he's a well-known television star even though he's not famous for anything. The creators just thought the convention of adding "TV's" or "Hollywood's" to an actor's name is funny.
* InternetBackdraft: Mike Vs Joel spawned many a flamefest back in the 1990s, to the point that Joel himself (allegedly) decided to have a little fun with the show's fanbase on USENET by anonymously [[TrollingCreator picking fights]] SAYING his replacement was better than Joel was.
* JerkassWoobie:
** Dr. Forrester has his moments at times, especially around his mother.
** Tom Servo can act a bit obnoxious and egotistical, but that's because he's incredibly insecure about his height and intelligence and has more than enough BreakTheHaughty moments to make you feel a bit bad for him.
** Kinga Forrester has her moments just like her father. As well, they also have them around Pearl.
* MemeticBadass: TheMovie has '''''[[foldercontrol]]

[[folder: The Amazing Rando ]]
'''''.
-->'''Tom''': Watch as Rando The Great constructs sets with only ''the power of his mind!''
** [[Film/TheFinalSacrifice Rowsdower saves us and saves all the woooooooooorrrrrrrrld!]]
* MagnumOpusDissonance: Most fans will rank ''Film/ManosTheHandsOfFate'' as one of the all time funniest episodes of the series. However, series creator Joel Hodgson admitted in an interview that he honestly didn't think that episode was their best work. He recalled that in the writing room they were all too caught off-guard by the oddness of the film, distracting them from writing really good riffs. He has said a few times that ''Film/IAccuseMyParents'' is his personal favorite [=MST3K=] episode, which most fans probably don't even have in their Top 10 (though the fans who ''have'' seen it consider it very good).
** [[CreatorBacklash None of the MST3K cast seem to like the Manos episode much]] if their comments in this [[https://www.youtube.com/watch?v=IjHXXX288zQ reunion video]] is any indication. This caused a bit of an awkward moment when upcoming new host Jonah Ray piped up with, "Well, as a fan, I loved it!" Also, interesting that Mike Nelson seems to have his own MagnumOpusDissonance. His favorite episode is Season 10's ''Girl in Gold Boots'', which isn't really a fan favorite either. Even the episode review section of the "Satellite News" website, describes the episode as [[http://www.mst3kinfo.com/?p=5703 "good, not great."]]
* {{Mondegreen}}:
** The theme song for the Mike episodes in seasons 5-7 feature Cambot saying "Show yourself!" But the muffled way Cambot speaks makes it sound like he's actually saying "Kill yourself!" Similarly, when Crow appears, he says "That's ''one'' O." But it almost sounds like he's saying "That's (or Bat) guano!" instead.
** In the original theme song for Joel, "shot him into space" can sound like "shot him in his face". This becomes something of an AscendedMeme in the Season 11 episode "[[Recap/MysteryScienceTheater3000S11E05TheBeastOfHollowMountain The Beast of Hollow Mountain]]" when it's used as a riff.
* MostAnnoyingSound: Pearl's ''constant'' screaming of "Clayton!" at the top of her lungs while she's sick in the "Deathstalker" episode.
* PeripheryDemographic: The series itself was actually surprisingly popular with younger children particularly during the Joel Era. (See WhatDoYouMeanItsNotForKids below.) Even though a lot of the jokes would either [[GeniusBonus go over their heads]] or probably be a bit too vulgar for their parents liking. But still a lot of the fan mail that was revealed at the end of an episode was sent in by kids still in Elementary School even though the series is more meant for Teens and Adults. This was more apparent during the early-to-mid '90s, back when the series was on Creator/ComedyCentral. When the series moved to the Sci Fi Channel in the late '90s, this was less apparent.
* PoorMansSubstitute: Paul Chaplin and James Moore as Crow and Servo, respectively, in the 2007 webtoon.
* ReplacementScrappy:
** Pearl Forrester managed to be this ''twice'' during the show's run; in season 7 when she replaced TV's Frank (it didn't help that her relationship with Dr. Forrester was almost the opposite of what Frank's had been), and then in Season 8 when she took over Dr. Forrester's role as the main bad guy. A lot of fans did warm up to her during the last three seasons, though, as she came into her own.
** A large portion of the fanbase considered Mike this when he first took over for Joel as the main host. This would eventually lead to the infamous Joel VS Mike flamewar, where the fans fought over which was the better host, and it got so nasty that for years afterwards, the subject of who you preferred was taboo within the fanbase.
** Largely averted with Bill Corbett's portrayal of Crow, who most fans grew to accept over time and in some cases even preferred to Trace Beaulieu's. It didn't hurt that by the time Corbett came on board, the fanbase was used to dealing with changes in the series, so his replacing Beaulieu wasn't as big of a deal.
** Averted, or even inverted, with TV's Frank versus Dr. Erhardt, and Kevin Murphy's Servo versus Josh Weinstein's.
* RewatchBonus: In the 2017 revival [[spoiler:Kinga's inventions are all inspired by a joke in the previous episode]].
* ScapegoatCreator: Poor Jim Mallon. ''Every'' cast member the show lost was immediately blamed on him not getting along with them, including Joel, who created the whole show and couldn't possibly be made to leave if he hadn't wanted to.
** In an interview, Hodgson stated that he ultimately decided to leave the show for the good of the show, as he knew tensions between Mallon and himself would only escalate further, causing the show to cease production prematurely. There were too many people Hodgson respected working on the show who would be devastated, financially as well as emotionally, if that happened, so Hodgson ''wanted'' the show to go on for their sakes. Which is why, in the end, Hodgson was happy that the show lasted for as long as it did without his involvement.
* TheScrappy: Professor Bobo tends to be this for many viewers. Many people cite his obnoxious voice and antics, as well as his incompetence, as a main source of criticism. Most likely [[InvokedTrope invoked]] however, seeing as the rest of the cast tend to find him rather annoying at times.
** Pearl Forrester tends to be this too, [[TheyChangedItNowItSucks mostly from those who enjoyed Clayton Forrester more]].
** Though the opinion is a relative minority, there are plenty of people willing to admit not liking Gypsy due to her grating voice. It's telling that the 2017 revival gave her a less grating (and more genuinely feminine-sounding) voice. (Explained in-universe by having Jonah give her a different voice because ''he'' couldn't stand her old voice, either.)
* SpecialEffectsFailure: Both purposely invoked and played straight. Invoked due to the hodgepodge nature of the show's props and puppets ([[NoBudget they were made from household appliances, knick-knacks and broken toys. after all]]). But played straight largely in the season one opening (Crow's head reveals the chroma-key effect used for the doors and his puppeteer can be seen before the "RobotRollCall" begins).
** Several theater shots reveal that Joel wears glasses (they can be seen any time he turns his head to the side) and Mike clearly isn't wearing a jumpsuit (his untucked shirttails are visible when he stands up). Not to mention both of them can be seen wearing head mounted microphones.
** In the 2017 revival, the more effects-heavy puppets required the riffs to be filmed without the movie playing, going off time stamps. This naturally means the occasional line is a bit out of sync with the movie.
** Hampton Yount has serious trouble syncing Crow's mouth movements to his lines. In the theater he often just leaves the mouth open the whole time, although that could be signal issues​ with the new radio controlled mouth mechanism.
** Jonah Ray's gargantuan 6'5" frame almost gives away that they aren't sitting in real theater seats as he towers over the fake backrest. If they were he would most likely be ''very'' uncomfortable.
* TaintedByThePreview: The trailer for the 2017 revival was called out by many fans for appearing to be put together by someone with absolutely no idea what the appeal of the show was, as it focuses on the host segments far more than the movie riffing, with only some brief clips of the theater that don't include a single line. Luckily, the largest Kickstarter backers who got an early look at the first episode were quick to assure everyone the riffs are still just as good.
* TheyWastedAPerfectlyGoodCharacter: Synthia, the clone of Pearl in the 2017 series. After an intriguing introduction that hints her CloneDegeneration is an act, she hardly ever appears outside of silently loading in the latest experiment.
* TheyWastedAPerfectlyGoodPlot: Joel returns for ''Film/{{Soultaker}}'', and he doesn't do any riffing with Mike and the Bots? (Joel explained that he wasn't able to help in the writing in this episode and didn't want to do anything he didn't contribute to.)
** [[FridgeBrilliance He was too busy fixing everything that was broken on the satellite.]]
* UncannyValley: During the opening host segment of ''Film/TheViolentYears'', Servo replaces his dome with a ventriloquist dummy's head, which frightens and disgusts the others. Crow suffers unbearable BrainBleach.
* ValuesDissonance:
** The references to PETA, which were common in the Joel era, can come across as this. At the time PETA was a respected animal rights group that no one really had much problem with. These days... [[RuleOfCautiousEditingJudgment let's just say they're a bit more controversial]].
** "Gypsy" is now considered an offensive slur for the Romani, making it pretty awkward to see it as a main character name.
*** Which is weird because one segment claims she's named for the large amounts of the mineral Gypsum used in her construction.
** The show has its fair share of uncomfortably transphobic jokes, most notably in the highly popular ''Mr. B Natural''.
* VindicatedByCable: This happened to many riffed films. This show is the only reason many of them have pages on this wiki in the first place.
** This actually ''backfired'' a bit. Some rights-owners saw the chance to actually make some money from a film which was only featured because it was a flop and tried to charge [=MST3K=] through the nose for the rights.
* VindicatedByHistory: Josh "J. Elvis" Weinstein's tenure on the show falls under this. Since the first season episodes were rarely shown on Creator/ComedyCentral, and the KTMA shows weren't widely available, Weinstein's tenure was frequently dismissed by many. (For example, one notorious CC promo referred to Weinstein's character of Dr. Laurence Ehrhardt as "a fake Frank".) However, recent DVD releases of first season shows, KTMA shows being available via the Internet, and his later work with WebVideo/CinematicTitanic, has given fans the opportunity to favorably reappraise Weinstein's work, particularly his talent for ad-libbing riffs.
** Weinstein would reference this during CT appearances by introducing himself as "the Tom Servo you don't like as much".
** Not so much the show -it's good and succesful, so there's no vindication to be made- but {{KTMA23}}, the channel were Season 0 was shot. Unlike both ComedyCentral and SciFiChannel who tend to steer away from the show as much as possible and preffer to pretend they were never involved with it, {{KTMA23}}'s current incarnation, {{The CW23}} just ''LOVES'' the show and cast to bits. While there is some obvious self-promotion going on by reminding people that MST3K began on their channel every time they get, they've also uploaded old clips of different comedy bits -Like the fake news show ''15 Minutes''- the performers used to do there and invited several of the cast back to revive old shows and events from the KTMA era. One example is Bill Corbett reviving old character -Bob Bagadonuts- in the very same new year's eve celebration special -The Melon Drop- that Kevin had created after it hadn't been done for more than ''20 years''. [[note]] Although the Melon Drop had been revived two years before his re-appearence. [[/note]].

* WhatDoYouMeanItsNotForKids: Kids do like the puppets. Yessir. And the humor in the puppet segments is fun; however, the actual movies they cover may still be scary to small kids, even with the riffing--which we should add [[ViewersAreGeniuses often goes over the heads]] of a lot of ''grown-ups'', let alone children.
* TheWoobie: Cambot at the end of ''Film/DangerDeathRay''. The movie had a large number of security cameras shot out by the protagonist, which ends up causing an emotional breakdown in Cambot.
