'''Note''': This article lists examples which take place within fandoms; not TV Tropes' opinion as to whether a change is for the worse. TV Tropes doesn't have opinions. The focus is on over-reaction about minor changes.

As a general rule, any time the translated version of an anime or manga makes any deviation from the original dialogue, it is likely to draw this reaction from some portion of the fandom. While there are often very legitimate reasons for fans to be less than pleased with a translation, many within the fandom will still be upset even when the changes are relatively minor or [[{{Woolseyism}} more effective than a literal translation]].

----
!!Examples:
* Don't ask fans of ''Anime/SandsOfDestruction'' if they like the ''[[VideoGame/SandsOfDestruction game]]'' or ''[[Anime/SandsOfDestruction anime]]'' better. The two are basically BroadStrokes adaptations to the point that they're AlternateContinuity; it helps nothing that production of the game began first, but the anime was released first, giving each a legitimate claim to being the "original" that the other changed.[[note]]It also helps nothing that there's a few hints in the game that characterizations may have originally been closer to the anime but were later changed: notice, for example, that Morte is extremely quiet and serious in the opening movie, whereas in the game proper she's a GenkiGirl, and Rhi'a is seen walking around with Naja but is never alone with him in the game's plot; the opening 3D movie would have likely been rendered early in production, and while changing a few sprites around is easy (the animations on the sprite sheet all exist no matter when or where you want to use them), it would be more trouble to reanimate a 3D scene, leaving the opening movie a relic of the game's "original" state that the anime was based on.[[/note]] The girls, in particular, have a problem with their personalities changing: in the anime, Morte is serious and driven and Rhi'a is TriggerHappy, whereas in the game, Morte is a [[PsychopathicManchild gleeful]] MadBomber [[spoiler:(even after she changes her mind about ending the world, she's still really upbeat)]] and Rhi'a is calm and mysterious. The [[Manga/SandsOfDestruction manga]] gets less flak, perhaps simply for being less well-known and never receiving any official release. Morte's insanity is dialed up a few notches from the game, but Rhi'a is the one who really changes, becoming a complete {{Cloudcuckoolander}} whose only real purpose is to be the PluckyComicRelief; her fans were less than amused. There's also the issue of voices; many fans of the game play it on a ROM simply because it offers the option to patch the voices back to the original Japanese, and of course anime fans continue the great SubbingVersusDubbing debate.
* Some people HATE what Netflix did in adapting ''Anime/{{Aggretsuko}}'', especially their removing Retsuko's drive to be successful at work in favor of wanting to get married and quit her job.
* ''Manga/AttackOnTitan'' suffers from this in the anime adaptation, especially in the second half. While some changes were welcomed because they provided more screentime or characterization without changing the overall story, the changes to the Female Titan arc have caused considerable debate among manga fans. This especially concerns the omitting of a key scene between Eren and Annie, as well as major changes to the last three episodes. However, the second [[CompilationMovie compilation film]] entitled "Wings of Freedom" will focus more on Eren and Annie's interactions.
* Many fans of the 2009 and 2012 ''Anime/BlackRockShooter'' dislike ''Black★★Rock Shooter: Dawn Fall'' for not continuing the anime's story and instead having a plot similar to [[VideoGame/BlackRockShooter the game]], as well as for changing Black Rock Shooter, Dead Master, and Strength's designs. And fans of the game dislike it for changing the antagonist from aliens to a human-created AI.
* The English dub for ''Manga/{{Bleach}}'' gets this a lot. From "shinigami" to "soul reaper", Ulquiorra's softer, more deadpan voice or how some of the English voice actors sound a little different from their Japanese counterparts. It might just be a tie between which gets more fan backlash: the difference in Hollow-Ichigo's roar or any changes in voice actors that occur over the course of the show.
* ''Anime/BubblegumCrisis Tokyo 2040'' was a BroadStrokes adaptation/ContinuityReboot of the original OVA series. Sources of controversy include Sylia becoming an [[TheAlcoholic Alcoholic]] DepravedBisexual instead of TheCaptain and TeamMom she was before; changes in character designs, including several that were inexplicable {{Exp|y}}ies of ''Anime/ElHazardTheMagnificentWorld'' characters; most of Priss's songs being discordant synth punk instead of [[The80s '80s]]-style pop rock; Boomers looking like generic robots that transform into generic fanged monsters; and inappropriate use of comedic sight gags.
* Many ''Detective Conan'' fans were outraged about the name changes and the title change to ''Manga/CaseClosed'' in the English release.
* The English dub of ''Anime/CodeGeass'' fell into receiving complaining. Lelouch/Zero's voice, in particular, was a point of contention, due in large part to his English VA not sounding enough like his Japanese one. However, there are at least some Japanese fans who seem to prefer Creator/JohnnyYongBosch's over the top and hammy performance over Creator/JunFukuyama's performance, which they consider to be monotone.
* ''Franchise/DeathNote'':
** ''Manga/DeathNote'' fandom splits less than equally into fans who think the scene on the roof is the best thing ever, and those who don't know what the anime producers were thinking. The anime ending has also been the subject of some debate, with some fans [[{{Narm}} finding]] it [[HighPressureBlood ridiculous]] and others beautiful.
** [[Series/DeathNote The TV drama]] has gotten this reaction from many fans, due to numerous changes. These include Light grabbing the IdiotBall with surprising frequency, L being a {{Jerkass}} looking like he [[MrFanservice stepped out of a pop video]], Mello being a SplitPersonality of Near manifested in a DemonicDummy, {{a|rsonMurderAndJaywalking}}nd Ryuk being played by Creator/JunFukuyama instead of his original Japanese VA, Shido Nakamura.
** The anime's adaptation of the Near/Mello arc has gotten this reaction from a sizable portion of the fanbase, as many major character scenes and moments were cut out of the anime, with Near and Mello themselves suffering the worst of it. According to analyses by manga readers, the anime removed roughly ''10 chapters worth'' of content from Near and Mello, partly resulting in their BaseBreakingCharacter status for anime watchers.
* ''Franchise/{{Digimon}}'' gets this almost every season. A [[Anime/DigimonTamers new cast]]? No [[Anime/DigimonFrontier partner digimon]]? No [[Anime/DigimonFusion digivolving?]][[note]]This is even worse considering that digivolution actually was introduced into the series later on.[[/note]] [[SeriousBusiness NO]] '''[[Anime/DigimonDataSquad GOGGLES?!]]''' Judging by how many times it's been ruined, you would think the series had died years ago.
* The first two seasons of ''Anime/DragonBallZ'' were dubbed into English by Creator/TheOceanGroup while being licensed by Creator/{{FUNimation}}, and the English dub handled and controlled by Saban Entertainment; however, the show suffered from poor time slot placement and didn't get a lot of mainstream exposure until it began airing on the Creator/CartoonNetwork, and then its popularity exploded. To meet the high demand for more episodes, [=FUNi=] made plans to dub the rest of the series, but broke off their connection with Saban, and realized it would be more economical to produce an in-house dub at their own facilities in Texas rather than outsource the work to Ocean in Canada, which they could no longer afford without Saban's funding. As a result, all the character voices in the third season sounded radically different from those in the previous two (before they were [[DuelingDubs redubbed]] that is), creating a fiery backlash among viewers who had been fans of Ocean's work. To be fair, [=Funi=]'s voice work at this time was admittedly pretty lousy, although they have since gotten better (see: ''Anime/FullMetalAlchemist2003''); rumor has it that they were recruiting people off the street with no prior VA experience during auditions, Frieza was voiced by a woman, and Puar and Chiaotzu were voiced by a librarian. However, while many of the voice actors had no prior experience in voice acting, most were to some extent. Sonny Strait (Krillin) had even voiced the original TOM on Toonami before his stint in DBZ.
** ''Anime/DragonBallZKai'' had some slight backlash of its own with Frieza, Bulma, Gohan, and Android 18 receiving new voice actors. Most of the hate seems to come for Gohan's voice actor, Colleen Clinkenbeard, since he now sounds younger which rubbed some fans the wrong way who are more used to his more gruff initial Funimation voice.
* ''Manga/TheFlowersOfEvil'': Very much the most vocal complaint of the anime. Some fans claimed the use of rotoscoping was ugly and ruined their enjoyment. In addition, claims of changing the mood of the show to a quieter tone and redesigning the characters were also detrimental. The manga's creator has since vocally supported the changes and states he oversaw many of them.
* ''Franchise/FullmetalAlchemist'':
** Readers of the ''Manga/FullmetalAlchemist'' manga sometimes had this reaction towards ''Anime/FullmetalAlchemist2003''.
** Fans often complain due to slight changes in manga and anime version of ''Brotherhood'', especially in pacing (early episodes tended to be cut down significantly so the show could get to the stuff that wasn't a retread faster). Also fans of both the manga and original anime often have this about the art style of ''Brotherhood''.
** Some fans of the 2003 anime had a reaction to "Brotherhood" very similar to the reaction manga fans had to the 2003 anime. It doesn't help that a number of them believed "Brotherhood" was going to be a sequel picking up where the 2003 anime left off rather than a manga-faithful reboot, and a lot of them ended up feeling very disappointed.
* ''Anime/GodzillaPlanetOfTheMonsters'' and its [[Anime/GodzillaCityOnTheEdgeOfBattle two]] [[Anime/GodzillaThePlanetEater sequels]] get this treatment from a large portion of the Franchise/{{Godzilla}} fanbase for replacing most of the monster-fighting action universal to the franchise for human-focused (and HumanAlien) pseudo-philosophical conflicts. Adding to this were the backstory novels which many people [[TheyWastedAPerfectlyGoodPlot found much more interesting than the films they supplemented]] for sticking closer to the tone of the other films. Some people even view the anime trilogy as among the worst films in the entire series, which is really saying a lot.
** On a related note, the designs of Mechagodzilla and King Ghidorah get a lot of criticism due to the vastly different appearances. Although Mechagodzilla is introduced more-or-less roughly resembling how it usually is (a robotic version of Godzilla), by the second movie its entire body had melted into an immobile city construct that doesn't even vaguely resemble Godzilla anymore. And in the end, [[spoiler:it never even fights Godzilla directly before being destroyed.]] Ghidorah's full body is never shown in the film, rendering him three worm-like strands whose fight with Godzilla is mostly static biting.
* [[Creator/{{GONZO}} Studio GONZO]]'s anime adaptation of ''Manga/RosarioPlusVampire'' was coldly received by fans of the manga for omitting much of the plot and turning it into a {{fanservice}}-filled series, with breast and {{panty shot}}s galore, and no CharacterDevelopment. Many fans to this day demand a reboot that's more faithful to the manga.
* ''Franchise/{{Gundam}}'' franchise:
** ''Anime/TurnAGundam'' initially received a poor reception among the ''Franchise/{{Gundam}}'' fandom, due to having little in common with the "classic" Gundam style used by the rest of the franchise. While it has gradually received a much more positive reception over time, some fans still complain about the overall aesthetics.
** Nearly every important SEED character had at least 3 (Athrun and Lacus had at least 4-6 apiece) different romanizations of their names, some of these are still in use over the official English transliterations.
** When ''[[Anime/MobileSuitGundam00 Gundam 00]]'' came around, the fans were against the idea that the new installment would include aliens (which, up to that point, had been a non-entity in the Franchise/{{Gundam}} franchise), and that the Gundams lacked "signature features" of Gundam designs, like mouth vents.
** ''Anime/MobileSuitGundamAGE'', in addition to the complaint about the inclusion of aliens [[spoiler:that aren't actually aliens but regular human colonizers abandoned by Earth on Mars that happen to have weird Mobile Suits]], generated discontent for being more child-oriented than other ''Franchise/{{Gundam}}'' series. Nowadays the criticism seems to stem more towards the awfully rushed story and less to a generic "They Ruined Gundam FOREVER!!!!11!1!" reaction.
** The 25th anniversary release of the original three ''Gundam'' movies notably changes the futuristic gun sounds with louder contemporary gun "dakka" noises. The background music is removed from many scenes in favor of louder battle explosion sound effects. In the second and third films, the ending credits music is replaced. The "Soldiers of Sorrow" song is moved from the Jaburo battle to the end credits, replacing the eerie choral music of the original. The third movie also does the same thing by removing "Lalah's Theme" from the end credits and replacing it with "Yes, My Sweet", itself moved from its original place in the Battle of A Baoa Qu and Amuro's escape. These changes undermine the mood of these scenes, using energetic action music for closing credits. Thankfully, they left the ending song in the first movie alone. There's always the original VHS releases if you can find them.
* The Studio DEEN anime adaptation of ''Webcomic/HetaliaAxisPowers'' didn't go over well due to the OffModel and stiff animation, stories being cut and pasted in random order throughout five minute episodes, censorship of nudity, and [[AdaptationDyeJob inexplicable changes to characters' hair and eye colors]] (as well as whitewashing darker characters). Creator/{{FUNimation}}'s dub of the series [[RatedMForMoney deviated heavily from the script at points to justify their "TV-MA" rating]], including jokes about the Holocaust and Nazis that ruined things for many fans. Although they later toned down the script in later dubbed episodes, there's still plenty of added jokes that don't go over well. For some other fans, it wasn't so much the scripting changes that ruined Hetalia, but the dub actors' voices not matching up to the ones they were already used to (along with the usage of heavy accents).
** Studio DEEN's adaptation of "Buon San Valentino" of ''Webcomic/HetaliaAxisPowers'', while providing enjoyment for some fans, was controversial in cutting out Prussia's part (explaining why Germany received a dating guide that only served to embarrass him), as well as any screentime for England and America. It also removed the final strip, in which a flashback draws a connection between Germany and Holy Roman Empire both giving Italy flowers.
* ''Manga/HunterXHunter'':
** The TruerToTheText 2011 version of the ''Manga/HunterXHunter'' anime got this reaction from fans of the original anime version.
** The original 1990s anime gets flak by some for being too derivative of the manga.
* People who got into ''Toys/{{Jewelpet}}'' for situating itself in the MagicalGirl genre were very disappointed with the [[Anime/JewelpetSunshine third season]]'s shift into a high school GagSeries.
* The fandom of Creator/KeyVisualArts tends to be very negative about the ''VisualNovel/LittleBusters'' anime, which was done by Creator/JCStaff. This differs from the adaptations for ''VisualNovel/{{Clannad}}'', ''VisualNovel/{{Kanon}}'', and ''VisualNovel/{{AIR}}'' which were all done by Creator/KyotoAnimation. It got to the point where when JC Staff was announced to make the anime, people treated Little Busters! as DarthWiki/RuinedForever ''[[ComplainingAboutShowsYouDontWatch before the first episode even aired]]''.
* ''Anime/MagicalGirlLyricalNanoha'':
** Surprisingly, not many complaints were made about Nanoha's barrier jacket having its red ribbon replaced with some brooch for TheMovie adaptation of the 1st season.
** You'll get a lot more complaints from fans of characters who were written out of the movie, however.
* Basically, any story inside the ''Anime/MazingerZ'' multiverse which goes three inches beyond the original concept. This include the anime version of ''Anime/UFORoboGrendizer'' (No Mazingers and Koji Kabuto as a sidekick), ''Anime/ShinMazinger'', ''Anime/MazinkaiserSKL'', and any other alternate universe to Go Nagai´s manga version. Exceptions are the two original stories (''Anime/MazingerZ'' itself and ''Anime/GreatMazinger'') (but some fans also didn´t like the Tetsuya/Koji switch...[[spoiler: subverted in the ''Anime/GreatMazinger'' GrandFinale and the story of ''Anime/{{Mazinkaiser}}'']]), ''Anime/{{Mazinkaiser}}'' (but some fans complained about the mecha "invulnerability"), general appearances in the many storylines of ''VideoGame/SuperRobotWars'', and ''Manga/ShinMazingerZero''. But most fans just don´t want heavy variants to the original idea.
* The English dub of ''Anime/{{Monster}}'' by Viz took some heat for changing the music (regardless of how it's still all the original show's music, just that some of it has been moved), and translating a name as Lunge, when it's generally agreed that Runge is the accurate version due to being a real German name. The major argument against this is that we're lucky the series even got a dub with its huge number of characters and episodes. Later when it was pointed out that all foreign adaptations feature these music changes, fans still blamed Viz for not trying hard enough to get the original track.
* This is basically the ''Franchise/{{Naruto}}'' fan base in a nutshell, with many former fans claiming that the Shippuden era, or anything following the [[spoiler:first]] Final Valley battle between Naruto and Sasuke contains poor characterization and lackluster writing compared to 'part 1'. Many fans also complained that the story focused too much on the main characters and not giving enough time to its side characters despite that it was basically the point of their roles.
** Fans got even more upset with The Fourth Great Ninja War when it turns out every bad thing that ever happened in the ''Naruto'' universe was because [[spoiler:Obito lost his crush and Black Zetsu retcons the entire series by claiming it was all his plan to revive Kaguya.]]
* When Netflix acquired the rights to ''Anime/NeonGenesisEvangelion'', Khara refused to use the old and fairly problematic ADV dub and subs, instead making their own English translation and [[TheOtherDarrin choosing an entire new cast themselves]], to the resentment of many long-time fans of the series. Because Netflix refused to pay for the rights to the ending theme "Fly Me to the Moon" however, the credits used instead another song from the OST in non-Japanese audio tracks, and [[HideYourLesbians Kaworu's "love" line was changed to "like"]] (which makes the most sense out of all the changes as the Japanese version used "ai", the word for "friendly love" which is translated as "like", but tell that to [[DieForOurShip the shippers]]) . Problem is, this was *already changed* more than once, and in fact the original VHS subtitles used "like" too. Some of these changes weren't even changes at all, in fact, [[MisaimedFandom and were only present on]] even older *fansubs*. However, there were no reports of the new voice actors receiving any harassment from angry fans.
* ''Manga/OnePiece'' received complaints regarding the English voices from 4Kids' dub of the series not fitting with the Japanese voices (the [[DubInducedPlotlineChange alterations to dialogue and plot]] would be [[{{Macekre}} a different trope entirely]]). Later, when the license changed hands from 4Kids to Creator/{{Funimation}}, a different section of the fanbase criticized the Creator/{{Funimation}} voices for not matching the ones 4Kids used.
* Having one of the biggest fanbases in the world, ''Franchise/{{Pokemon}}'' has naturally gathered quite a few examples over the years.
** One of the most common complaints about ''Anime/PokemonTheSeries'' is its tendency to deviate from the rules of the games (both intentionally and unintentionally), to the point where feats that are impossible in the games are arguably one of the show's trademarks. One of the longest running debates about the anime is whether these changes are justified within the show's world, or are just cheap {{Ass Pull}}s.
** The show also runs into this with many of its attempts at BreakingOldTrends. ''Anime/PokemonTheSeriesRubyAndSapphire'' received quite a bit of hate in its heyday for leaving behind Misty and Ash's original Pokémon team, as did ''Anime/PokemonTheSeriesBlackAndWhite'' for trying to overhaul [[IneffectualSympatheticVillain Team Rocket]] into a trio of serious villains. Notably, the latter actually was largely reverted back to how it was before due to fan complaints.
** An infamous point for the anime's dub occurred when the voice actors were replaced. This crossed a line with fans who had grown attached to the iconic 4kids voices, with plenty of them swearing off the dub from ''Battle Frontier'' onward.
*** Speaking of the dub, it's received increased backlash over the years for its habit of replacing the Japanese soundtrack, with the dub's replacement music usually seen as highly inferior to the original. The complaint is most intense with ''Anime/PokemonTheSeriesXY'' and ''Anime/PokemonTheSeriesSunAndMoon'' for dub soundtracks that are considered exceptionally bland and unfitting, with many fans deeming these particular seasons of the dub to be all but unwatchable.
** ''Anime/PokemonTheSeriesSunAndMoon'' got a lot of backlash when it was first revealed, due to the change to a more cartoony art style and given a [[DenserAndWackier comedic]] school-based setting, which many fans felt was a cheap attempt to compete with ''Anime/YoKaiWatch''. It also received backlash for changing up the plot and characterization from the much-praised ''Sun and Moon'' games, most notably [[spoiler:removing Lusamine's emotional abuse of Lillie and Gladion (which changes the characters' entire arcs).]]
** ''Anime/PokemonHorizonsTheSeries'' immediately got hit with backlash from a subset of fans simply because it wouldn't be starring Ash, who would end up retired as a character after ''Journeys''. New protagonists Liko and Roy were subsequently hit with criticisms for simply not being Ash.
** ''Manga/PokemonAdventures'' also receives backlash for not being enough like the games. It has a reputation for changing personalities and roles, such as making Ruby's dad Norman abusive, turning several of the Kanto cast into villains, and giving Shauna's personality a 180 by making her pessimistic.
* It's not uncommon to see ''Anime/PrettyCure'' fans tear each new season due to character designs, plot, and even ''how the logo looks'', all before the season has even ''aired'', with one subset of fans constantly insisting that the series needs to go back to how it was in [[Anime/FutariWaPrettyCure 2004]] before the changes in newer seasons "ruined" everything. This also extends to the ''Anime/PrettyCureAllStars'' movie series - people were not happy when they learned that ''New Stage'' was reducing 11 of the 28 featured Cures to TheVoiceless and TheCameo, when they had speaking parts of the original. This is also compounded with how ''[=DX3=]'' was pretty much so action packed and rather fair in speaking roles despite the tons of Cures featured it becomes such a ToughActToFollow.
** ''Anime/SmilePrettyCure'' vs. its Creator/SabanBrands dub ''Glitter Force''. Many ''Pretty Cure'' fans have already declared this trope just by the title change alone before the show even aired, with many just cringing because of the 4Kids stigma.
** ''Anime/KiraKiraPrecureALaMode'' got a lot of flack when ExecutiveMeddling forced the season to lack the traditional hand-to-hand combat and violence that ''Pretty Cure'' is usually known for. A similar reaction was observed years earlier when ''Splash Star'' had to tone down the violence from the first two seasons.
* ''Manga/ThePromisedNeverland'' had a devisive ending to say the least, which led into the anime's second season making some massive changes that the fanbase has not responded well to. The worst being the complete removal of the well-recieved Goldy Pondy arc and expediting the reveal that [[spoiler: Norman was alive]] much sooner than in the manga's story.
* ''Anime/RebuildOfEvangelion'':
** ''Rebuild of Evangelion 2.0'', in contrast with its predecessor, [[ItsTheSameNowItSucks 1.0]]. Specific examples include the change of Asuka's surname from Sohryu to Shikinami, alterations to Asuka's personality and role, alterations to make Rei more emotionally open [[SugarAndIcePersonality than she was in the series]], the introduction of a new character (Mari), and the appearance of Kaworu [[EarlyBirdCameo much earlier than he appeared in the original series]].
** ''3.0.'' received an even stronger case of this from fans, due to taking the LighterAndSofter feel from the last two movies and throwing it straight into DarkerAndEdgier territory, taking the plot in a way virtually no one anticipated... Long story short, it drastically turned everything into a direction that ''Evangelion'' has never experienced before.
* ''Franchise/SailorMoon'':
** There's a vocal subset of fans who hate the [[Anime/SailorMoon 90s anime]] for changing stuff from the original [[Manga/SailorMoon manga]]. Common criticisms tend to be the amount of {{Filler}} episodes and {{Padding}} added to keep the show from [[OvertookTheManga Overtaking the manga]].
** The Creator/DiC dub has a multitude of hatesites dedicated to it, by people who claimed to get up early to watch it when they were little, for any change made by the dubbers. After the license switched from [=DiC=] to Cloverway (though with the same studio, Optimum, still handling production), there are fans that still cry foul over the new translation team opting to keep the Japanese [=BGM=] in episodes, as they had been used to the [=DiC=] music and felt it was more appropriate. The inconsistent translations and dub terminology also didn't help matters, nor did the recasting of a few characters (Sailor Moon, Sailor Mercury, and Sailor Venus in particular).
** This went full circle with the announcement of the new Creator/{{Viz}} dub of the classic series consisting of all 200 episodes (including the unreleased ''Stars'' arc) and new series ''Anime/SailorMoonCrystal''. A VocalMinority called for the old dub names, and sometimes actors, to return for the new dubs.
*** Of course, in Canada and the United Kingdom, it's more a case of "they changed it, now it's gone". The show [[NoExportForYou cannot legally be obtained]] in this form up north.
* ''Anime/SailorMoonCrystal'':
** Some fans would have preferred to see as many of the classic cast return as possible, given Creator/KotonoMitsuishi's RoleReprise.
** Some people are complaining that the OP isn't "Moonlight Densetsu". This may partly stem from the initial assumption (mistakenly spread by some fansites) that Music/MomoiroCloverZ's popular CoverVersion, which ended up being the ThemeSong for the Creator/{{Takarazuka|Revue}} {{Revival}} of the ''[[Theatre/SeraMyu musicals]]'', was to be used for ''Crystal''.
** Some people are complaining how ''Crystal'' is different from the anime in the '90s; this is strangely enough also the [[ItsTheSameNowItSucks opposite trope]] because ''Crystal'' is basically an animated retelling of [[TruerToTheText the manga chapters]].
** The complaint of Zoisite and Kunzite no longer having an official relationship, which was simply an invention of the '90s anime (in no small part thanks to Creator/KunihikoIkuhara), [[ShesAManInJapan and some translations turning Zoisite into a woman]] has been this for some YaoiFangirls and LGBT fans.
*** Similarly, the complaint that the Shitennou and Inner Senshi were now officially in love with each other in their past lives, stating that this goes against [[WordOfGod Naoko Takeuchi]]'s original intent with them. [[note]]She drew an image of the Shitennou and Inner Senshi pair up, but aside from a hint of Venus liking Kunzite, she never worked the idea into any official material[[/note]]
** And let's not get started on how some feel about Toei's liberal use of CGI animation for the show.
** The Usagi/Haruka {{Ship Teas|e}}ing struck a cord beyond simple ShipToShipCombat from those so used to the 1990s anime depicting Haruka and Michiru as so close. The [[spoiler:kisses]], which screamed of infidelity, is what set fans off. This all, however, is true to the original manga.
** Latin American fans weren't happy with the Latin Spanish dub not using the localized names, Belinda Martínez not reprising her roles due to not working at Dubbing House (the dubbing studio), and Adriana Olmedo (a complete unknown who's only other notable role is Sam from ''WesternAnimation/TheLoudHouse'') voicing Sailor Jupiter instead of Creator/MarianaOrtiz (the daughter of the original Latin Spanish voice of Sailor Jupiter, Araceli de León) as everyone wanted.
* ''Anime/SaintSeiyaKnightsOfTheZodiac'':
** When it was announced that the CGI-animated ''Manga/SaintSeiya'' adaptation by Creator/{{Netflix}} would change Andromeda Shun's gender from male to female, the fandom was NOT pleased, with complaints about misandry and queerphobia/genderphobia being thrown around.
** This became worse with the fandom in the Latin American dub, one of the most controversial changes was [[Series/TheHouseOfFlowers Dario Yazbel]] as Seiya, who has an uninspired and plain voice compared to the late (and highly energetic) Creator/JesusBarrero. The choice was questioned and widely criticized by fans, considering Seiya could get a better choice in Creator/IrwinDaayan, who made his voice for the TV version of ''Saint Seiya: The Hades Saga''.
* ''Anime/SaintSeiyaOmega''. The style changes in the characters design, the "future" storyline, the stepdown in the mythos concepts, the cloths changed from physical existence to gems projections...in fact, this whole leaded to a BrokenBase war between [[Manga/SaintSeiya "classic version"]] followers and the supporters of the Omega version
* Dub fans of ''Manga/{{Saiyuki}}'' reacted this way when Reload and Gunlock was acquired by a dubbing team in California rather than ADV Films in Texas, resulting in an entirely new voice cast; many disliked the different tones the new voices gave the characters, such as Sanzo's voice becoming ''extremely'' deep, Goku's voice losing the young-yet-mature tone, Hakkai losing the suaveness, and Gojyo losing his sexy accent.
* The anime of ''Manga/SchoolLive'' was met more coldly by manga fans than first-time viewers thanks to this. Changes to Miki's character and the introduction of TeamPet Taromaru are the main points of contention. The final episode was also disliked for [[spoiler:removing Rii's FreakOut, removing the helicopter crash that caused said freak-out, removing Yuki's scene where she finally killed a zombie (with her, instead, trying and ''failing'' to hit one), and making the zombies leave the school on their own]].
* Due to its age and multiple adaptations, ''Anime/ScienceNinjaTeamGatchaman'' has had cases of its own vocal fan complaints and criticism over time:
** The animation style and music in ''Gatchaman II'' and ''Fighter'' are considered inferior to the original series, as the sequels used a brighter color palette that fans felt looked too gaudy and the background music was felt to be too overpowering. The design of the New God Phoenix also received criticism, due to it looking more overdone and childish.
** The 3-episode OVA remake in 1994 isn't looked upon too highly due to it utterly redesigning all the characters, including giving Dr. Nambu a ridiculous pompadour and pink suit.
** ''Anime/GatchamanCrowds'' is considered part of the franchise, but the complete re-imagining of the concept and lack of any of the recognizable cast (save for a redesigned Berg Katze, and a heroic version of Leader X who is an AI) left fans feeling it was an InNameOnly off-shoot made as a cheap cash-in. The changes most controversial include the complete elimination of the bird motif from the team's uniforms, the warriors gaining their powers from spiritual beings instead of being well-trained and having some vague futuristic technology, the true leader of the team being an alien panda mascot, and the terminology changes ("Science Ninja Team" to "G-Crew"). [[spoiler: And then there's the complete overhaul of Katze's origin, in which he's an alien and a ''former'' Gatchaman who went rogue, which some fans decried as ruining the show.]]
* ''Manga/SgtFrog'': Purists tend to be incredibly vocal about Funimation's dub of the anime here, although in the minority, but even in its original form the anime attracts a lot of scorn from fans of the manga. Common complaints are that the show was sanitized for younger viewers, reworked into a marketing gimmick, and the [[BadassDecay changing of Dororo]] from a TechnicalPacifist who routinely stood up to his friends when they tried doing something wrong into a whiny ButtMonkey who barely even interacts with them.
** Manga Keroro even breaks the fourth wall to lampshade this, telling everyone to clean up their act because they're going to be an anime.
*** Tropers on the WildMassGuessing page have gone even further, suggesting that the anime is a cheap money-making scheme orchestrated by the Keronians.
* ''Anime/SonicTheHedgehogTheMovie'' elicited this reaction from some fans when Knuckles was referred to as a mole. ItMakesSenseInContext to devoted fans, though. The person calling him a mole probably has no idea what species he is (and let's be honest, [[InformedSpecies he sure doesn't look like an echidna]]).
* Much of the scorn for ''Anime/SonicX'' essentially comes from splitting up Earth and Sonic's World. The lack of {{Funny Animal}}s on Earth makes Sonic and his friends into oddball aliens, resulting in human characters acting differently towards them than they do in the games. This change opened up the opportunity to introduce the LonelyRichKid Chris, the series' human self-insert character, who becomes close to Sonic after saving him from drowning.
** Taken ''up to eleven'' with the ending of the Metarex saga and what it originally was meant to be depicted as in the Japanese version. Tails in the 4Kids dub acts sad because he is being asked to fire at his close friend Cosmo to stop the Metarex destroying life, but once encouraged he does so quite quickly despite a lot of his character development being getting close with her only to off her amazingly fast. The original? Tails slams his head down on the console unable to do it and spends a LOT of time unable to push the trigger, even putting the safety over it as he falls apart with the gravity of his [[SadisticChoice cruel task]]. Once Cosmo tells him here to do it, he screams that he loves her as he finally fires, before curling up in sheer shock as Cosmo admits he loves him too before she disappears. The following episode's screaming at Sonic for being unable to do anything to save her is also massively toned down from the original. Fans felt that the toning down of these important scenes were criminal.
* The anime adaptation of ''Manga/SweetBlueFlowers'' is not off the hook either, though. Where killing most of the sub-plots does help to streamline the narrative, it also demolishes a lot of background about the relationship between Akira and Fumi, both in the present time as in their past. This leaves quite a few viewers not acquainted with the manga wondering just ''what'' the hell cheery Akira sees in Fumi, who gets across as a whiny, spineless brat without much characterization.
* ''Futari wa Milky Holmes'', the third season of ''Anime/TanteiOperaMilkyHolmes'', is much more serious in tone than previous seasons and focuses on two new protagonists. This results in [[FanonDiscontinuity fans pretending it never exists]] and over 70% drop in blue-ray disc sales.
* ''Anime/TenchiMuyo'' has problems due to multiple alternate universes, revivals, and retconning. Major flak comes for the Ryo-Ohki 3 OVA which was made 8 years after Ryo-Ohki 1 and 2 ended. It has so many retcons to characters' fates that it can be summed with the song "Everything You Know is Wrong". Tenchi Muyo GXP and War on Geminar also are belong to the Ryo-Ohki universe, despite not having the series' title character Tenchi or any other main characters actually in them more than cameos.
** To fully explain why ''Anime/TenchiInTokyo'' hasn't gone over well with fans would take quite some time. Aside from the changed art (which many have called downright ''ugly'') and the somewhat unresolved ending, you have new characters that are [[BaseBreakingCharacter base-breaking]] at best. Also, there is now a plot line of the title character being a student and the mundane interactions (and people) seen there and we're introduced to ''the one'' hotly debated character in Sakuya/Yuugi, whose [[BitchInSheepsClothing true colors]] turned off viewers and whose presence adds yet another person to Tenchi's already bursting at the seams harem. And finally, instead of following up on the clear [[SequelHook sequel hook]] left open at the end of Tenchi Universe, the show was yet another AU, asking the audience to become re-invested in new versions of the same characters all over again, instead of continuing the story of the previous show.
* There are many ''Anime/TengenToppaGurrenLagann'' fans that had this reaction towards translations of show terminology that didn't match up with what was currently in use among the already-existing fandom at the time. There was also some discontent about the switch from Creator/BrettWeaver to Creator/KyleHebert as the voice actor for Kamina when the license for the show changed hands from ADV to Bandai.
* Admittedly, [[OffModel some of the fanbase's grievances]] with Studio DEEN's adaptation of ''VisualNovel/UminekoWhenTheyCry'' are legitimate. But when you have people complaining that they ''used the wrong music in a scene'', you know this trope has struck with a vengeance. ''Umineko'''s original visual novel received a Platform/{{P|layStation3}}S3 port, fans of the original novel were upset to see the original artwork being replaced by more professional and detailed images. Fans of both series dislike the ''slight'' change in art style from ''Higurashi'' to ''Umineko''.
* ''Manga/UQHolder'' is basically a sequel series to ''Manga/NegimaMagisterNegiMagi'', with a supporting character, Evangeline, from ''Negima'' becoming a secondary protagonist in ''UQ Holder!'' All well and good. Popular, even. Then there's the fact that Evangeline's adult form underwent a minor redesign (she has a different hairstyle and slightly different facial structure), and her personality is notably more mellowed out, and she goes by the alias "Yukihime". This kicked off a bit of a BrokenBase between fans of ''Negima'' who think this trope is in play and that "Yukihime" is so differentiated from Evangeline that she might as well be a different character, and fans of ''Negima'' who attribute the changes to ArtEvolution and the fact that ''UQ Holder!'' takes place 80 years after ''Negima'' ended.
* The [[AnimeOfTheGame anime adaptation]] of the [[VideoGame/ValkyriaChronicles game]] ''Anime/ValkyriaChronicles'' received a lot of flak from fans of the game for some admittedly justifiable reasons: CharacterExaggeration, key characters (Leon and Kreis) being omitted, MoodWhiplash, changes to key events (Lupus and Batomys), changes to some characters, an unwanted LoveTriangle shoe-horned in. Some reasons weren't so justifiable: having the squads at 10 men each rather than 20, getting the armor wrong, not including certain recruitables in squad 7, putting some characters in the wrong classes they were listed as in the game.
* This is why the OVA to ''Anime/TheVisionOfEscaflowne'' was very badly-received by fans. The movie is a ReTool of the series. For example, Hitomi was originally an ordinary, rather jovial high school girl, but became an EmoTeen in the movie, and that upset a lot of people. If you find yourself in the company of ''Escaflowne'' fans, it's best not to discuss the movie.
* The ''Manga/WanderingSon'' anime gets a lot of this from fans of the manga. At first it just came from the art style. Compared to other adaptations, especially ''Manga/SweetBlueFlowers'' by the same author, the anime simplifies the style for ease of animation, with some fans disliking the changes. Character designs were also changed and many characters received [[AdaptationDyeJob different eye colors]] in the anime, going from realistic colors to a wide range of fantastic ones. As a story, the series suffers from being very different from the manga. Chronological order is changed, the series begins InMediasRes which doesn't work for a manga driven by continuity and KudzuPlot, OutOfCharacterMoment scenes are added, scenes are changed, and the ending of the anime is dramatically different from its equivalent of the manga. It drives more of a "can't change your sex, and you'll just grow out of this" moral, which is in stark contrast to the manga, and to how many transgender people feel in real life. Nitori's reaction at the end of the manga is vastly different in the anime. [[spoiler:In the anime she takes a girl's comment about her voice breaking with a stride and a true smile, while in the manga her reaction is dull and in shock; no smile either.]]
* ''Anime/YashahimePrincessHalfDemon'' was hit with this when it was announced that the Latin American dub would be done, not in Mexico, but in Argentina. The backlash from the Latin American fandom of ''Manga/InuYasha'' was immediate, and Creator/LauraTorres (Shippo's VA) [[https://www.youtube.com/watch?v=vhnv-4AJ_uE expressed disgust at the fact that none of the cast from the original series was even called to reprise their roles]], calling it an insult to her fellow voice actors and the fans.
* ''Anime/YokaiWatch'':
** ''Yokai Watch'' changed all of its English dub cast between seasons due to money issues. This was met with much anger and disappointment by fans. These changes likely lead to the dub's cancellation (among Level-5 failing to make the series catch on in general in America).
** ''Anime/YokaiWatchShadowside'' has been met with mixed reactions by adult fans because of this. It changes the formula to be darker and more action-based. This makes it more like the original games, yet at the same time many scorn it for "ruining" what made the anime different from other {{mon}} series like ''Pokémon''.
