Western Animation is no exception to the rule: the surest sign of a fan is their hatred for other fans.

* The fans of ''WesternAnimation/TheSimpsons'' all got along fine, once upon a time. Now war rages between those who believe the show is as fun and sharp as it ever was, and those who think it's [[JumpingTheShark about a decade or so past its use-by date]] and [[SeasonalRot new episodes are stupid and unfunny]]. Then there are those who acknowledge that the overall level of quality may have gone down but are satisfied if [[RapidFireComedy if it still makes them laugh a few dozen times an episode]].
** Even the fans who don't like it anymore can't agree exactly on "when" it started sucking. Was Season Five the last good season? Seven? Three? Ten? Nobody can agree.
** "The Computer Wore Menace Shoes." One half says it's one of the worst episodes because the second half is contrived and out of place and the other half found it hilarious.
** "Lisa's Sax". Some call it a cute, heartwarming episode with an awesome ending to boot, while other can't get past Bart's sad subplot (If somebody hates this episode, chances are that will be the reason) and despise the character pampering Lisa is given in it.
** Fans are ''very'' divided over the following episodes, all of which were controversial:
*** "[[BlackComedy Homer's]] [[KafkaKomedy Enemy]]": Was the relentless torture of one-time character Frank Grimes funny (demonstrating how an ordinary person could not survive in the chaotic Simpsons universe) or incredibly mean-spirited?
*** "[[SoapboxSadie Lisa the Vegetarian]]": Was Lisa right to express her sudden loathing of meat consumption and then learn to tolerate it, or was it an unnecessary development that greatly flanderized her character?
*** "[[{{Retcon}} The Principal and the Pauper]]": Was this episode a clever, interesting twist on a classic Simpsons character (Seymour Skinner) or an insulting waste of time that permanently ruined him and the previous character development he went through?
*** "[[BlackComedyRape "Homer vs. Dignity]]" Was the major humiliation Homer experiences in this episode (including the scene where he is raped by a panda) funny and well-deserved, or is it so painful to watch that it destroyed any remaining purity the show retained after its quality dropped?
*** "[[DudeNotFunny The Boys of Bummer]]": Was this episode a clever satire of the ways in which over-patriotic sports fans take games too seriously and forget the importance of sportsmanship, or a seriously cruel and unfunny episode where Bart is subjected to relentless abuse (and is even driven to suicide at one point)?
* ''WesternAnimation/FamilyGuy'' is in basically the same position as ''The Simpsons'' now.
** For a good summation of trends, cutaway gags have gone from unsteady experimentation to get the formula down, to legitimately funny cutaway gags that generally use the same formula (and so get old after a few years), to cutaways that derive comedy from subverting the expectations of those savvy to the formula, to cutaways that forget the "gag" part, the cutaways for which the gag is is based on mocking the vary concept of cutaways. All of these are very different types of humor.
** Sexually ambiguous Stewie vs evil genius Stewie.
** Multiple reviewers have complained that the newest seasons have effectively run out of ideas and don't make any effort to change things, while fans have either sympathized their position or sided with Creator/SethMacFarlane and see them as ridiculous.
** Brian's NoHoldsBarredBeatdown by Quagmire in "Quagmire's Dad" on whether Brian deserved it or not.
** [[ButtMonkey Meg]]'s abuse being [[RefugeInAudacity funny]] or [[DudeNotFunny not]].
** There is a sharp division on fans about who likes "Quagmire's Dad", "The Juice is Loose", "Road to the Multiverse", "You May Now Kiss the...Uh...Guy Who Recieves" , "Tea Peter", "Go Stewie Go", "Be Careful What You Fish For" and ''especially'' "Not All Dogs Go to Heaven".
* ''WesternAnimation/{{Futurama}}'' is catching up too, but nowhere near as much as ''The Simpsons''.
** Though it's fashionable among critics to bash the "new episodes," there's a lot of internal debate as to at what precise season/year/moment the show begins being "new."
** The movies especially tend to be love-it or hate-it. Some were just happy to have new ''Futurama'' after 5 years. Others felt that it wasn't doing justice to the original run. The debate has (mostly) settled down, with people agreeing that the problem was format, having to create a movie that could be divided into four television episodes.
* Similarly, ''WesternAnimation/SpongeBobSquarePants'' fans are split between those who like every season of the show and those who think the newer seasons are either downright unwatchable or simply not as good as the first three.
** In admittance however, the creator doesn't even really want to do the show anymore.
*** A lot of fans are torn on "[[{{Squick}} House Fancy]]", "[[WhatAnIdiot A Pal for Gary]]", "[[KafkaKomedy Keep Bikini Bottom Beautiful]]", "[[FamilyUnfriendlyAesop Yours, Mine and Mine]]", "[[BadBoss Patty Caper]]", "[[TheyWastedAPerfectlyGoodPlot Shuffleboarding]]", "[[DudeNotFunny One Coarse Meal]]", "[[AcquiredSituationalNarcissism Driven to Tears]]", "[[{{Wangst}} A Day Without Tears]]", "[[MadeOutToBeAJerkass Stuck in the Wringer]]", "[[BlackComedy Good Neighbors]]" and "[[FelonyMisdemeanor Little Yellow Book]]".
*** Fans are also divided over the movie - was it a hilarious animated comedy that did justice to its source material, or was it an overblown, cash-grab that foreshadowed the show's gradual decline? Was Season 4 the last good season, or the first bad one?
** Some fans have noticed an increase in quality since Season 8, and admittedly there have been a few gems in that and Season 9 so far. Still, some fans refuse to acknowledge any improvements.
** There's a group that prefers the UnCancelled seasons to the original seasons.
* Most fans agree that the ''Franchise/{{Transformers}}'' franchise has had its ups and downs, but which is which is forever the subject of heated debate. ''WesternAnimation/TransformersAnimated'' is simultaneously the best and worst show ever.
** Or maybe the franchise has been "Ruined FOREVER!" [[http://tfwiki.net/wiki/Ruined_FOREVER (the trope naming franchise, actually)]]: "Fans realize something Hasbro does not, that robust 25-year-old billion-dollar franchises, while seemingly healthy, are in actuality as fragile as two bricks tied together with tissue paper." That line pretty much describes the fanbase's position on everything.
** There are ''Transformers'' fans who think the original was the ONLY series, with all other subsequent series to be inferior knockoffs. These people are known as "Geewunners", and can be identified by their distinctive rallying cry of "[[http://tfwiki.net/wiki/Trukk_not_munky TRUKK NOT MUNKY!]]". On the flipside there are "Reeduners"(a derogatory take on "geewun" based on "G1", a parody of "redone") who hate everything old and groan every time a past series is references.
** Arguments over the Bay films, comic vs cartoon, Marvel vs Dreamwave vs IDW...
** The 2009 film ''Transformers: Revenge Of The Fallen'' divided the fanbase, with half of the fans considering the film an unwatchable monstrosity that ruined the reputation of the franchise, and the other half loving it regardless, looking past the tacky storyline and bad acting and instead enjoying the plentiful amounts of action, huge explosions and highly complicated special effects in the film.
*** It's seriously to the point where the only thing fans can agree on is their hatred of Pat Lee, and Squick at Kiss Players. And even then, there's room for other opinions, especially those who find creepy imagery, and therefor Kiss Players, funny.
* ''WesternAnimation/{{Ben 10}}'' fans can't seem to decide amongst themselves whether Gwen is the [[EnsembleDarkhorse only good thing about the show]] or its [[JumpTheShark debilitating ruination]]. Her ''[[WesternAnimation/Ben10AlienForce Alien Force]]'' version gets a lot of this too.
** Strange as it sounds, nobody really questions whether or not Ben and Gwen are "[[IncestIsRelative meant to be together]]", as it's more of whether or not the Gwen/Kevin relationship was an ass-pulled cover story, or a legitimate attempt to separate characters they forgot were related (ironically, they WEREN'T supposed to be related: it was last-minute to give them a good reason why Gwen should even be on the trip).
** ''WesternAnimation/Ben10AlienForce'' and ''WesternAnimation/Ben10UltimateAlien''. You either [[LoveItOrHateIt Love 'Em or Hate 'Em]]. This goes double for ''WesternAnimaton/Ben10Omniverse'', which was intended to go back to the LighterAndSofter roots of the franchise, only to receive mixed reaction.
* {{Toonami}} fans were split on [=TOM4=] (the flat-faced robo-alien one). Naturally, they were also split when the ''original'' TOM replaced [[WesternAnimation/SpaceGhostCoastToCoast Moltar.]] As well, Creator/CartoonNetwork's NetworkDecay propagates this.
* ''WesternAnimation/AvatarTheLastAirbender'' fandom are notorious for this. The Zutara fans and Kataang fans get into ShipToShipCombat for example. There's other DieForOurShip moments that annoy the more sane fans of the show.
** Season three is also controversial for the fanbase. If you don't like it and explain why, you're likely be harassed for not being a 'true fan', but if you do like it, you're dismissed as a drooling, zealot fanboy/girl.
** Azula's series finale VillainousBreakdown is a subject of much controversy as well. People who think the influence of Azula's father on her actions gives her a valid FreudianExcuse, and that Azula deserves to be forgiven and redeemed, are accused of downplaying her numerous wicked actions over the course of the series, including advocating genocide of the Earth Kingdom in the finale. People who think that Azula has no excuse for her actions, and that not only was her VillainousBreakdown well-deserved, but that she deserves to spend the rest of her life suffering in prison, are accused of overlooking Azula's mental fragility and her father's influence on her actions. The fact that Bryke [[ShrugOfGod left Azula's fate ambiguous]] will likely leave fans warring over this issue for a ''[[PassThePopcorn long]]'' time.
*** Heck, ''Azula herself'' is guaranteed to cause arguments in the fandom, between those who think she's way too powerful and those who think she's awesome. But then again, the same could be said for [[FanDumb almost all the cast]].
** Gene Luen Yang's post-TV-series SpinOff comics, ''ComicBook/AvatarTheLastAirbenderThePromise'' and ''ComicBook/AvatarTheLastAirbenderTheSearch'', are a very fraught topic in the fanbase, specifically the way they depict the later lives of the characters and the development of their romantic relationships.
** How Aang defeats Ozai has created quite the break, itself. There are those who feel Aang's "spiritbending" trick (or as many call it "The Easy Button") was a lame AssPull for the sole purpose of not having Aang kill Ozai, rendering three seasons worth of training to master Water, Earth, and Firebending worthless. Others feel that if Aang hadn't mastered the elements and achieved true Avatar status, he never would've been able to access the spiritbending trick at all and saw it as [[TakeAThirdOption a perfectly acceptable third option]]. And, of course, there's the overwhelmed minority who's just willing to chalk it up to RuleOfCool and apply the MST3KMantra to any argument to "how".
* SequelSeries ''WesternAnimation/TheLegendOfKorra'' is even more prone to ideological splits.
** The fan base is divided over the {{steampunk}} setting, even though the ''original series'' already [[FanDumb used it]] on a smaller scale.
** [[ShipSinking Confirmation]] that Tenzin is [[OfficialCouple Katara and Aang's]] son has paradoxically caused a resurgence in Zutara[=/=]Kataang [[ShipToShipCombat shipping wars]] (complete with DieForOurShip).
*** And, as with the previous series, there are plenty of [[ShipToShipCombat shipping]] [[DieForOurShip wars]] for the new cast, too, with no less intensity than [=ATLA=]'s fights.
** A comment by Andrea Romano revealing that the entire original cast is dead prompted some sections to deem Korra and her crew {{Replacement Scrappy}}s.
** With the new trailer some fans began debating whether or not the setting is ''too'' modern.
** There are also some concerns that the setting has become too Western.
** One of the biggest points of contention is over Korra's [[AmbiguouslyBrown race and ethnicity]]. One side insists that Korra is of color, and fanworks depicting her [[ButNotTooBlack with lighter]] or [[RaceLift white skin]] trivialize the importance of a dark-skinned woman as a main character. The other claims that race is a non-issue with fictional characters, and Korra's skintone should be a matter of fan creators' individual preferences. Rather curious considering that Korra shares an [[BraidsBeadsAndBuckskins ethnicity and skintone]] with Katara and Sokka, and the Water Tribe are explicitly based on the [[EskimoLand Inuit]].
** Another contention over Korra is the depiction of her build. Much like with the aforementioned skintone issue, it largely breaks into two camps. The first decries any fanwork that depicts Korra with less developed muscle tone than in canon. The second camp claims that Korra's build should be a matter of fan creators' individual preference. Depictions of Korra with greater muscle tone than in canon draw far fewer complaints.
** Following the online premiere of the first two episodes, the fanbase fractured ''again'', this time over whether or not Korra is being written as a saviour-esque character in regards to bender privilege.
** And then there's the first season finale. It should be mentioned that ''Korra'' was supposed to be a twelve-episode MiniSeries, which means it was going to be a series finale as well. Given the fanbase's reaction to the previous series's finale, this is fully expected. And it's for similar reasons, even.
** While few would dispute that there's at least some grain of truth to first-season BigBad Amon's complaints of non-bender oppression by benders, fans are sharply divided over the ''extent'' to which the VillainHasAPoint, from "there are a few bad seeds among benders, but there's no institutionalized oppression" to "the entire government is a vast [[FantasticRacism Fantastic Racist]] conspiracy, [[GodwinsLaw benders are Nazis]], and Amon is a [[YourTerroristsAreOurFreedomFighters freedom fighter]]!"
** Some fans are wondered if Book Two: Change was better or worse than Book One: Air.
* ''WesternAnimation/AdventureTime'' has a fiercely divided fanbase.
** Flame Princess, Princess Bubblegum or Marceline?
** 13-year-old PB or 18-year-old PB?
** Were Marceline and Princess Bubblegum implied to be a couple in "What Was Missing," or are they just friends?
** Is Lemongrab an insufferable {{Jerkass}}, a pathetic JerkassWoobie, or a sympathetic [[TheWoobie Woobie]]?, Or a [[PsychopathicManchild hilarious sociopath]]?
** Fionna and Cake - best thing that happened to the show, or disgusting pandering to the fanbase?
** The darker Myth Arcs are also starting to divide fans. Some find them too dark and out of place, others believe it adds great depth to the series and is part of the fun.
*** The more extreme side of this is that some people prefer the worldbuilding/backstory episodes to Finn's various and all-too-unsatisfying romance plots, lamenting when an episode focuses on him instead of a secondary character or event
** Most of the Fandom is split apart by episodes like "[[MadeOutToBeAJerkass Apple Wedding]]", "[[WhyWouldAnyoneTakeHimBack Red Throne]]", "[[DesignatedHero Too Old]]", "[[ShipSinking Frost and Fire]]", and "[[SoapBoxSadie Wizards Only, Fools]]".
** The most controversial part is whether or not the break up between Finn and Flame Princess was really all that necessary
* The ''WesternAnimation/DannyPhantom'' fandom has an ongoing war between "true fans" and "anti-fans." The true fans believe in only writing fandom and drawing FanArt they believe creator Butch Hartman would approve of, and tend towards being MoralGuardians over any fora they're part of. The anti-fans, on the other hand, believe in fanart as an expression of the fan's thoughts and fantasies, from [[CrackPairing crack]] / [[SlashFic fandom pairings]] to drawing porn of the characters (which was probably how the war started anyway).
* The '90s ''WesternAnimation/{{X-Men}}'' cartoon, AdaptationDistillation or AdaptationDecay?
** Same goes for ''WesternAnimation/{{X-Men Evolution}}'', but worse.
* The ''WesternAnimation/{{Daria}}'' fanbase was once split over the issue of CharacterDevelopment. Some enjoyed watching Daria open up to her peers, make new friends, get a boyfriend, soften her hard line, etc. Others, identified much more closely with Daria as a cynical misanthrope, declared TheyChangedItNowItSucks.
** The entire character of Tom Sloane was a massive splitting point for the fandom.
** Four words: "Depth Takes a Holiday".
*** Three more words: "Daria!: The Musical".
* ''WesternAnimation/TheBoondocks'' is either a funny, thought provoking show, or it's in danger of becoming what Dave Chappelle feared [[Series/ChappellesShow his show]] was turning into (i.e. a show that was getting [[UnfortunateImplications the wrong kind of laughs, for the wrong reasons]] from the [[PeripheryDemographic wrong group of people]]).
* There are two main views on ''WesternAnimation/SouthPark'': either it really [[GrowingTheBeard hit its stride]] when it moved from a show comprised solely of [[BlackComedy crude, shock-value humor]] to one focused just as much on social/political commentary, or it completely [[JumpingTheShark went to hell]] by turning into an AuthorTract. The thing with ''South Park'' is, though, that it can sometimes be as polarizing to its fanbase as it is to people in general. Combine that with [[LoadsAndLoadsOfCharacters a town full of people]] and the tendency for [[NegativeContinuity things to stay relatively the same despite earth-shattering events]], and you end up with a show that can have half its fanbase loving how it's using a character/joke/plot/etc., and the other half ''hating'' it, meaning the whole thing is constantly a Broken Base, over any number of issues from any given episode.
** You believe it or not, Cartman has been a victim of this in later years by the same fans. Yes, a good fan base loves Cartman because he is funny as hell and the show would not be the same without him, but some viewers claim that Cartman's ComedicSociopathy was exaggerated into him becoming an asshole extremely callous and lack of feelings with his friends and even family, and would not be very strange call it a challenge as TheScrappy in his humor becoming in DudeNotFunny. Many people hate Cartman by episodes like the end of "Kenny Dies". He is mostly hated by Kyle's fans.
*** A similar case would be his fight between him and Wendy. Several fans of the series (even fans of Cartman) felt comfortable that Wendy would have won in the fight with him. While there are other fans who hated her even more since she won.
** And let's not get started on "You're Getting Old" and "Ass Burgers". Several fans weren't happy with these episodes for being overly dramatic, derailing the characters (especially Stan), and ultimately led to absolutely nothing but an excuse to bash Stan and the audience at the same time.
** The existence of anime-style fanart and the ShipToShipCombat in the fandom itself have caused further splitting of hairs.
** A lot of characters have been this for the show, as well:
*** Butters was probably the first example. He went from EnsembleDarkhorse when he was a side character to being hated by a lot of fans due to his becoming one of the main characters, and his perceived {{Flanderization}}. Nowadays, he's used less often, but more effectively.
*** Kyle went from this JerkWithAHeartOfGold with traces of TheWoobie to a DesignatedMonkey and a {{Foil}} for Cartman. Some fans do not like his Designated Monkey status, while others are annoyed by his newfound obsession with stopping Cartman. Some also blame him for stealing screentime away from Stan, while some others are happy to see him focused on more often.
*** Then there's Cartman himself, and whether his antics are still funny or if his actions starting in "Scott Tenorman Must Die" rendered him beyond sympathy and likeability.
*** Randy Marsh's increased role is either met with amusement or irritation, some going as far as to say that Randy's bone-headed attitude has helped run the show into the ground.
* In the case of ''WesternAnimation/EdEddNEddy'', it's the episode "If It Smells Like an Ed". There are fans that either hate it for being [[KickTheDog the cruellest blow]] to [[FailureHero the Eds]] ''ever'', or consider it among their list of favorites for being the first half-hour episode in the series and have elements of DetectiveDrama.
** The later seasons of ''Ed Edd N Eddy'' had the kids attending school. Some fans thought it was a refreshing change of pace, others thought it was the series JumpingTheShark.
** As for the finale movie, Jonny and his [[spoiler: derailment into a joke villain]] have been met with plenty mixed results.
* Did the more character-focused, less humorous 4th season of ''WesternAnimation/TheVentureBrothers'' [[GrowingTheBeard Grow the Beard]] or [[JumpingTheShark Jump the Shark]]?
* ''WesternAnimation/TeenTitans'' was notorious for its Robin/Starfire vs. Robin/Raven [[ShipToShipCombat fandom war]]. It got so bad that stating your preference was a quick way to [[SeriousBusiness make]] [[DieForOurShip enemies]]. There were even little online cultures around the ships--Robin/Starfire fandom tended to consider themselves more [[OfficialCouple well-adjusted]] than the alternative, whereas Robin/Raven fandom often considered themselves more mature due to the [[JustFriends complex]] [[LikeBrotherAndSister nature]] of their fandom.
** Beast Boy and Raven pretty much won this by being lampshaded in the final season and the closing issues of the comic based on the series, as well as becoming canon in the D.C Universe (albeit in a WillTheyOrWontThey way).
** The series finale "Things Change": Brilliant and bittersweet way to end the series where Beast Boy learns a lesson about letting go, or a confusing and anti-climactic mess that goes against the mood of the series and leaves way too many unanswered questions?
*** Beast Boy/Raven or Beast Boy/Terra?
** Should Red X's identity have been revealed, or does it not really matter who he is? Another debate that continues to echo long after the show's end.
** Whether or not ''WesternAnimation/TeenTitansGo'' is a fun comedy that manages to properly make fun of the characters and the DC Universe as a whole or an abomination that mocks the memory of the original series is a debate that overshadows almost everything else regarding the Teen Titans...[[RuinedForever other than the quality of the current comics run]].
* An overlap with Film and Live-Action TV: There are two factions of ''Film/{{Ghostbusters}}'' fans: the Ghostheads, who prefer the Columbia Pictures film and its animated series ''WesternAnimation/TheRealGhostbusters'', and the Go-ers, fans of Filmation's 1975 live-action series ''The Ghost Busters'' and 1986 animated series ''WesternAnimation/FilmationsGhostbusters''. The fandom is mostly divided on which animated series came first, and on which ghost-busting premise (proton packs vs. dematerializers) is better.
** Not so much on which came first; ''The Ghost Busters'' came definitively first, which is why the Columbia films' follow-up toon had to add "The Real" to the title, as a way to [[WritingAroundTrademarks get around the fact that Filmation wasn't about to give up the naming rights again]].
* Never, ever bring up the ''WesternAnimation/StarWarsTheCloneWars'' series on a forum. You will immediately be flamed for liking the new series over the old 2D [[WesternAnimation/StarWarsCloneWars Clone Wars]] cartoons. There are people who like the old series because it's more "mature", while the new series is a "kid's show". Then there are the people who say that the old Clone Wars series is "childish, plotless, and completely stupid", while the new Clone Wars series is "full of mature themes, real story, and wonderful characters."
** Also, never, ever mention Ahsoka Tano. If you do, you will find your thread flooded with people who either think she's a "great character" or is "a pointless, stupid, annoying addition to ''Franchise/StarWars''."
* ''WesternAnimation/TomAndJerry'' has had a broken base for decades, and it should come as no surprise seeing that the protagonist and the antagonist in any given short is sometimes left up to the viewer's opinion. Jerry's {{Hatedom}} can be quite passionate, however.
* [[Film/AFairlyOddMovieGrowUpTimmyTurner Grow Up Timmy Turner]]: Live action version of The [[WesternAnimation/TheFairlyOddParents Fairly OddParents]]. There are [[{{Hatedom}} people who detest this movie]] and who view it as violating canon. Also, [[ShipToShipCombat Shipping Wars]] play a part in this because according to the live action movie [[spoiler:Timmy and Tootie are meant to be]]. Not to mention that many fans point out that it seemingly [[spoiler:violates the canon of "Channel Chasers"]]. On the other hand, there seem to be a number of fans who are looking forward to it.
* ''WesternAnimation/ScoobyDoo'' fans now have to make the same hard choice Shaggy faces on the [[WesternAnimation/ScoobyDooMysteryIncorporated new series]]: his best friend Scooby or his previous partner in mystery solving now romantic interest Velma.
* When ''WesternAnimation/{{Doug}}'' left Nickelodeon for ABC, the base was ''very'' broken over whether the new series was good or not. That the Disney version changed the voice cast didn't help.
* ''WesternAnimation/{{Rugrats}}'' fans can't seem to decide whether ''WesternAnimation/AllGrownUp'' was a good idea or if it was a horrible spinoff that killed every positive element from the source cartoon. The same can be said about the episodes that came [[UnCancelled after the show's first cancellation and resurrection]], as well as Dil and Kimi showing up.
** At one point, these got more hate than the post-movie Sponge-Bob episodes, despite not changing much apart from additional characters.
* The ''Franchise/MyLittlePony'' fandom is deeply broken when it comes to the generations. Many fans of the original series (the specials and ''MLP n' Friends'' TV show) hated ''WesternAnimation/MyLittlePonyTales'' due to the AnthropomorphicShift and SliceOfLife elements compared to the fantasy-based original, along with the more cartoony look. Some fans hate the LighterAndSofter original TV series in comparison to the dark and gritty SugarApocalypse-ridden pilot. Fans of ''those'' series are torn between whether the direct-to-video G3 episodes were any good or not, especially due to the fact it's [[TastesLikeDiabetes way more saccharine]] then the generations before it. A lot of the modern "[[PeripheryDemographic bronies]]" that came in with ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' hate anything that isn't that show (though among the brony community there exists a relatively widespread respect, if not liking, for G1). But nearly all of the fanbase agrees that [[DorkAge the short-lived G3.5 was a horrible idea]].
** MyLittlePonyTales also had fans who disliked the original for being too dark and edgy. And both fans of Tales and G3 questioned if Hasbro is doing the right thing by making FIM DarkerAndEdgier.
** This spreads to fans of the toy series as well. G2 gets the most hate, due to the fact the toys look ''[[YouDontLookLikeYou nothing]]'' like any other MLP toy-line before or since. G4 gets a small amount of hate too, both from fans of ''My Little Pony'' toys and the typical fan of the source cartoon, due to ShowAccuracyToyAccuracy. Although a lot of hate of the G4 toys is because [[EverythingsBetterWithPrincesses Princess Celestia]] is pink.
** There are some fans of the 80's cartoons that actually '''don't''' like ''Friendship is Magic'', believe it or not.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic: The fanbase is split on pretty much every conceivable issue.
** Has the show undergone SeasonalRot? If so, when? Is the show better or worse now that Creator/LaurenFaust has left? Have the current writers run the show into the ground, or have they done a good job following up the first two seasons?
** Mention RuleThirtyFour on any pony thread and watch the flames spread. Good example: ponychan (the most serious) vs fimchan (the porn) vs [[ImageBoards Derpibooru]] (the troll).
** There exists a division among the fandom regarding which of the two royal sisters, Princesses Celestia and Luna, is more fit for role of Equestria's leadership.
** Fan-favorite [[MemeticBystander background pony]] (and [[EnsembleDarkhorse fandom-mascot]]) [[AscendedFanon Derpy Hooves]]. Was her portrayal in "The Last Roundup" an offensive portrayal of the mentally disabled or not? Was re-editing the episode to change her voice, eyes, and name the right course of action or PoliticalCorrectnessGoneMad? And this isn't even getting into the subject of whether she should've gotten a speaking role in the first place.
** Then there's the kerfuffle over "The Mysterious Mare Do Well": over the Mane Cast's plan to deflate Rainbow Dash's ego: needlessly cruel, a much-needed ego check for Rainbow Dash, or a valid ''plan'' that was executed badly?
** Any episode with morals or aesops that are either [[BrokenAesop broken]], [[AccidentalAesop by accident]], or [[FamilyUnfriendlyAesop family unfriendly]] is sure enough to split the fanbase.
** And now there's some debate over the fan-game ''VideoGame/MyLittlePonyFightingIsMagic''. The fans are divided between [=RainbowCrash88=]'s instrumental themes (Applejack's and Twilight's) and Whitetail's electro-style themes (Rarity's and Pinkie's).
*** The bigger debate with that game regards the beta that leaked onto the internet, which the project head disowned and nearly halted further production over. Is it an unbalanced, unplayable mess (his words), or is it still a decent albeit unpolished game? And then the project got hit with a C&D from Hasbro. The fandom's subsequent divided viewpoints set the various pony forums ablaze.
*** This has ''mostly'' died down, though, since someone released the completed Tribute Edition.
** Rainbow Dash possibly being a lesbian was once a major hot spot for many fans. The issue was that, what with the show having multiple "don't judge a book by its cover" Aesops, assuming she was lesbian/fillyfooler just because of her rainbow mane and [[LesbianJock tomboyish attitude]] struck many fans as very wrong. This was compounded by [[BeamMeUpScotty presumably]] WordOfGod stating it (she totally didn't; [[NoHuggingNoKissing quite the]] [[StatusQuoIsGod opposite]]) and by Rainbow Dash being a LauncherOfAThousandShips. Thankfully, the debate has not only died down, but has been engraved in the fandom's memory as a rather memetic event that is now looked back on quite fondly.
** There's also a very divisive scene in "A Canterlot Wedding Part 1": Yes, Twilight turned out to be right about the Cadance we saw and had anyone listened to her, a disaster would have been prevented, but were the rest of the Mane 6 and Celestia really just being Jerkasses who forgot the Aesop of "Lesson Zero," or were their reactions justified by how Twilight had been acting lately, that and just how outlandish her claims were and her complete lack of evidence to back them up?
** Almost immediately after [[spoiler:[[NothingIsTheSameAnymore an alicorn Princess Twilight]]]] was revealed, the fandom seemingly underwent fission overnight, splitting into three groups: those who think this move will [[RuinedFOREVER ruin the show forever]], those who think the show will be about the same one way or another or even improved, and those who don't really care one way or the other and just want to watch their damn horses, thank you very much. It often boils over into the "should Creator/LaurenFaust have stayed on the show?" arguments mentioned above.
** Spike/Rarity shipping. Does Rarity reciprocate? If she does, is it pedophilia? What if she waits until he grows up first? Is Spike's crush on her real love, or just infatuation?
** The ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'' movie has been ''very'' divisive of the fanbase. When the film, about humanized versions of the ''Friendship is Magic'' characters in high school, was announced, most fans were not happy with the idea. The first trailer didn't really help matters. However, the second trailer, and more released details about the film, started to cause a divide. Certain fears about the concept were quelled so many fans were not as pessimistic toward the film as they initially were. After the film was released, it managed to bring a few more fans to its side. But it's still a pretty divisive issue among the fans. It's either a cliche high school drama show, or a cute, funny movie that does justice to its source material.
** In shorthand considering most of the above, the fanbase for [=FiM=] is so thoroughly broken that it plays out like a microcosm of the above mentioned divides between generations.
* The Creator/WarnerBros fanbase is very divided over ''WesternAnimation/LoonaticsUnleashed''. Some see it as an interesting take on ''WesternAnimation/LooneyTunes'' that needed some work but is still SoCoolItsAwesome, while others see it as an utter disgrace that made [[Creator/TexAvery Avery]] and [[Creator/ChuckJones Jones]] spin in their graves.
** Happening all over again with ''WesternAnimation/TheLooneyTunesShow'', with people debating over the different personalities/roles of the main characters, the neighborhood setting, and the overall {{sitcom}} comedy style replacing the slapstick and cartoon gags of the original shorts.
** It has been observed that, like its star Michigan J. Frog, ''OneFroggyEvening'' only "performs" for certain people.
* ''WesternAnimation/TheRenAndStimpyShow'': Everything after John K.'s original run on the series is polarizing. Many fans will say that the Games episodes are an insult to the original show, but many others will say they were good enough in their own right. Same with the Adult Party Cartoon episodes.
* While Creator/KennedyCartoons had a bit of a {{Hatedom}} for a while, many fans began supporting them to the point where now fans are divided whether their bouncy animation was [[AnimationBump very well done]] or [[OffModel very ugly]].
* In a less extreme case of the above, people are divided on whether Creator/ToonCity is on par with Creator/TMSEntertainment, Creator/StudioGhibli, Creator/CarbunkleCartoons, [[JonMcClenahan Startoons]], [[Creator/WaltDisneyAnimationUnits Disney's studios in Los Angeles, Japan, and Australia]], and the like, or if they're only on par with the likes of Creator/RoughDraftStudios, Creator/MoiAnimation, Creator/DRMovie, and Creator/JMAnimation.
* ''WesternAnimation/HeyArnold'' fans are hotly divided on the infamous [[LeftHanging cliffhanger ending]] to the series. Because of a rumored final movie that was to have resolved the show's remaining plotlines, fans are now divided between those who are fighting for the movie's revival and those who are satisfied with how things ended, or feel the movie would not live up to a decade's worth of built-up fan expectations. Mentioning which "side" you are on is a quick way to start a bloody argument.
* Was ''WesternAnimation/TeenageMutantNinjaTurtles1987'' the best adaptation of the turtles and a great cartoon, unfaithful but a decent show in its own right, or a horrific injustice to the franchise?
** ''WesternAnimation/TurtlesForever'': The perfect GrandFinale, or a thinly veiled TakeThat at the '87 cartoon?
** ''WesternAnimation/TeenageMutantNinjaTurtles2003'': Is the fifth season (the "Ninja Tribunal") a solid conclusion to the original plot lines of seasons 1-4, or is it too much of a departure from them? Were all the Ninja Tribunal characters a welcome addition, or did they become too much of a SpotlightStealingSquad and take too much time away from the main characters?
** Asking a group of Shellheads, who all grew up with a different series 'Which is better, the '87 cartoon, 2k3, or 2012?' will not end prettily.
* ''WesternAnimation/{{Recess}}'' fans are torn on the DTV movie, ''Recess: Taking the Fifth Grade'', which was released two years after the show ended. One side loves it, while the other side found it too boring compared to the rest of the series. Both bases ''do'' agree, however, that T.J.'s [[TheOtherDarrin new voice actor]] [[UnusualEuphemism whomped]].
** ''Recess: All Growed Down'' and ''Recess Christmas: Miracle on Third Street'' have one half of the base complaining that they were only made up of previous episodes linked together, while the others are happy about that, [[KeepCirculatingTheTapes as Disney stopped showing reruns in 2011 and there aren't any official season sets]].
* ''WesternAnimation/CodeLyoko'' fans are torn over the new ''Series/CodeLyokoEvolution''. Many are happy to see the series again while others are decrying the live action replacing the 2D.
* The ''WesternAnimation/AmericanDragonJakeLong'' fandom is considerably torn between whether the art design change from season 1 to 2 was a good thing.
* The UnCancelled seasons of ''JohnnyBravo''. While some fans liked the larger central cast and more kid-friendly humor, other fans hated the {{Flanderization}} and ArtShift.
* In-Universe case in ''WesternAnimation/TheTwistedTalesOfFelixTheCat'': Fans of "The Fuzzy Bunny Show" argued over which part they like more. (When he says "nick woo" or "neck woo"). They even [[SeriousBusiness fought over it]].
** Out-of-universe, opinions differ on which of Felix's voice actors was better; Thom Adcox-Hernandez or Charles Adler.
* Just try to ask a ''WesternAnimation/TotalDramaIsland'' fan about how they feel on any of the characters, especially Duncan or Courtney. No seriously, ask. You're either going to be told about how amazingly awesome or annoyingly awful they are. And this goes for ANY character in the show.
** Since season 4, the most controversy usually comes regarding Mike and/or Zoey- there are those who consider them as offensive, screenhogs, or terrible role models, whereas others argue that they're funny or very relatable characters. Mike's portrayal of DID is a hot topic- some consider the portrayal of a mental disorder as a joke as inaccurate and offensive, and some don't find it a big deal and enjoy his personalities or find the portrayal accurate after all.
* ''{{Superjail}}'' encountered a big example of this trope after the second season premiered, as the story format in episodes had changed along with the animation style (Augenblick had been too busy with ''UglyAmericans'', so the job went to Titmouse). Cries of RuinedForever could be heard, although there were fans that wound up on the defensive of ''any'' sort of criticism, claiming that anyone who didn't like any new stories had to be anti-character development and not a "real" fan. Likewise, certain season 2 critics also asserted that those who appreciated anything weren't real fans.
** Season 3 was a less extreme example of conflicting fan opinions, although there are those that still miss the Augenblick team and consider the Titmouse episodes to be too cartoony in style.
** Some fans of season 2 presented the opinion that season 1 was far too sexual and nonsensical, which others didn't agree with and made another divide.
** Personality changes in the characters have divided other fans: Is Warden better when he's more sadistic or more childish? Did Jared's increase in snarkiness ruin his original ButtMonkey personality? Were the Twins ruined and made too weak after having their alien heritage confirmed? You'll see quite the debate on these, among others.
** Lord Stingray joining the cast is either seen as the staff bringing in a new character to keep the show fresh, or a completely unnecessary and obnoxious addition.
** Alice's backstory confirming her as {{Transsexual}}. There are those that believe her story was a foregone conclusion and something that helped make her seem a little more sympathetic, while other fans claim it ruined their guessing games about her genitalia and became enraged that she didn't have an ambiguous gender or that her bulge just wasn't a sight gag.
** The very existence of RuleThirtyFour in the fandom can spawn much debate and flames in certain parts of the internet. It's either seen as reasonable to exist considering the adult nature of the show, or as an abomination and proof that fans are ruining the show for their own strange ships and fantasies. This is also coupled with ShipToShipCombat over slash pairings (usually male/male, rarely female/female) vs. the het. Anime-style fanart or works by the East Asian portion of the fanbase are another can of worms.
** There are even debates on whether or not the Mistress is more likable as a hippie since her radical personality transformation at the very end of "Stingstress". That, and what caused her to become a hippie ([[spoiler:Alice sleeping with her]]) is known to upset a particular faction of fans because of the assumption that it [[ShipSinking was the creators thumbing their noses at Warden/Mistress]].
** Season 4 being six episodes (reasons currently unknown) has caused another split: Fans who still want to watch it, and fans who have decided the show's as good as cancelled/dead and claiming that no one should bother (the anger over Warden/Mistress not being canonized also overlaps with this viewpoint) .
* If you're a fan of ''WesternAnimation/CodenameKidsNextDoor'', chances are you think the show's finale "OP: INTERVIEWS" is either a great ending to a great show or a straight up GainaxEnding from start to finish that messes up the formula of the show for the sake of having a TearJerker BittersweetEnding.
** The [[spoiler: Galatic KND]] is either an awesome plot twist or a total AssPull.
** Also, you may consider [[spoiler: Chad stating that he's a GoodAllAlong double agent during "OP: TREATY", despite the attacks on the KND he made since of the end of the 2nd season, to be either a last-minute AssPull made for arbitrary reasons, or an acceptable twist that you think actually makes sense.]]
** Opinions also differ on [[spoiler:Heinrich's UnsettlingGenderReveal]] in "OP: CARAMEL".
** There's also the ShipToShipCombat, which is still going on in some form years after the show ended.
** Did the show take itself too seriously? Was its CerebusSyndrome a good thing or not?
* ''WesternAnimation/GravityFalls'': Was the infamous TrollFic ''Dipper Goes to Taco Bell'' just good, {{Squick}}y fun, or a horrible fanfic that's so disgusting it makes the aforementioned ''Cupcakes'' look like ''DoraTheExplorer''?
** It's pretty safe to say that a majority thinks it's a horrible fanfic that makes the aforementioned ''Cupcakes'' look like ''Dora the Explorer''.
** Is Dipper trying to impress Wendy adorable or one hell of a RomanticPlotTumor?
* Trying to get people to decide whether ''WesternAnimation/SanjayAndCraig'' is either one of the most decent Nicktoons to come about since ''Avatar'' and/or is a love letter to the nineties, or if it's ripping off ''WesternAnimation/RegularShow'' and/or is just as awful as, say, ''WesternAnimation/FanboyAndChumChum'' is like trying to fit a camel through the eye of a needle.
** Also ''WesternAnimation/{{Breadwinners}}'', for the same reasons.
* ''WesternAnimation/RegularShow'': "[[KickTheDog The Best Burger]] [[YankTheDogsChain in the World]]", "[[TookALevelInJerkass Do Me a Solid]]", "[[CruelTwistEnding Do or Diaper]]", "[[FamilyUnfriendlyAesop Think Positive]]" and "[[BadBoss Muscle Mentor]]" are the most divisive episodes of the series.
** ESPECIALLY the first and third aforementioned episodes. Did both episodes have {{Cruel Twist Ending}}s, or were the endings a SugarWiki/MomentOfAwesome for Benson and Margaret?
** The AlternateCharacterInterpretation of Mordecai and Rigby can get pretty heated sometimes.
** Is season 4 just as good as the past seasons or SeasonalRot?
* ''WesternAnimation/LooneyTunes''
** If Daffy better as a screwy trickster or a greedy jerk? Fans of the former claim he's funnier, while fans of the latter claim he feels more "human".
** ''Fresh Airedale'' is a very polarizing short. Some say it was supposed to convey a message of two-faced jerks coming out on top and the underdog being left out in the cold. Others say it was a mean-spirited, unfunny, flat-out horrible cartoon. This was dealt with in the DVDCommentary, in which a negative IMDb review was quoted.
** Are Pepe Le Pew's shorts funny or just creepy?
** Speedy Gonzales is a ''huge'' BaseBreaker.
** Whether the [[DorkAge Seven Arts shorts]] (1967-69) are even worth watching.
** Even BugsBunny isn't immune to this, even by his ''own creators''. Some view him as a charismatic icon that defined the cartoon KarmicTrickster trope or basically a heroic SmugSnake. The Bugs vs Elmer shorts are of particular debate, some believe they consist of some of the most iconic shorts in the series, others feel Elmer was so pitiful Bugs' usual runaround looked more like an unpleasant glorified bullying.
* The ''WesternAnimation/GoofTroop'' fans who think Pete is the dad from hell and Goofy deserves to win Father of the Eon vs. the ones who think they're NotSoDifferent, and that neither is totally awful but neither is perfect. This split seems to come mainly from people who prioritize [[GoodParents kindness]] (or, alternatively, [[AbusiveParents cruelty]]) and ones who prioritize [[BumblingDad competence]]. Though there are some who think [[DracoInLeatherPants Pete is a great father]] or that [[RonTheDeathEater Goofy is a terrible one]], they're usually outside the realm of the debate.
* Even the ''Franchise/SonicTheHedgehog'' fans are divided on which cartoon series was better for the series as a whole.
** Was ''WesternAnimation/SonicSatAM'' a great cartoon series that greatly developed Sonic's character and added more depth to the series or was it an unfaithful adaptation of the beloved video games that was too dark for its own good?
** Was ''WesternAnimation/AdventuresofSonictheHedgehog'' the most faithful adaptation of the ''Sonic'' games or was it an immature version of the famous hedgehog?
** Was ''WesternAnimation/SonicUnderground'' a decent attempt at a whole different take on the franchise, or a bastardized mess that barely connected to the series in any way?
* Considering how Seth Mcfarlene's previous shows fared, ''TheClevelandShow'' is of exceptional debate. Is it either a redundant lower quality copy of ''FamilyGuy'' with excessive "black guy" jokes, or a decent spin off that kept better moderation of humor and characterization than the former show?
* Fans seem completely split over ''{{Thomas The Tank Engine}}'s'' shift to CGI animation. Many fans find it a complete betrayal to the original model series, or a necessary move that opened up more potential for characterization and flexibility story wise.
