History YMMV / XMenFilmSeries

** [[Characters/MarvelComicsCyclop Cyclops]] is the leader of the team and main character in many of the comics, but he's DemotedToExtra in ''Film/X2XMenUnited'' and [[spoiler:killed off within a few scenes]] in ''Film/XMenTheLastStand''. This is also seen as a waste of actor Creator/JamesMarsden, who many agree was a pitch-perfect casting choice. An adolescent Scott Summers (portrayed by Creator/TyeSheridan) does have a significant role in ''Film/XMenApocalypse'' and ''Film/XMenDarkPhoenix'', though, so the AlternateTimeline repaired some of the damage.

** [[Characters/MarvelComicsJubilee Jubilee]] is generally one of the most iconic and celebrated characters in the X-Men, but the original film trilogy reduced her to a background character who doesn't speak. ''Film/XMenApocalypse'' managed to give her a speaking role and even have her tag along with Cyclops, Jean and Nightcrawler to the mall, but it isn't much more than a cameo and she gets capured by Stryker shorty after and isn't part of the FinalBattle. Not helping matters is that moments of Jubilee using power in both timelines are [[DeletedScenes deleted scenes]], with the ''X-Men Apocalpyse'' one just merely having her restart an arcade machine for Scott and Jean.

* StrangledByTheRedString: The supposed "[[InformedAttribute great]] love" between Logan and Jean Grey is hard to take seriously since they only knew each other for about five days ''at most''. The majority of the first film's plot takes place over roughly two or three days, then Logan goes off to Canada to find out about his past; they spend a day or two more in each other's company in the second film as they prepare to stop the villain, and she dies at the end of the mission, and in the third film, she's come back evil and spends most of their scenes together crazily beating the crap out of him. Plus, in the first two films, ''Jean was already in a long-term, loving relationship with Scott''.

* OnceOriginalNowOverdone:

** While the source material is well-known, the movies have had a major impact on how general audiences picture the X-Men. Many fans who were introduced to the franchise via the films believe that ComicBook/{{Rogue}} is a timid teenager who steals other people's superpowers, that [[Characters/MarvelComicsProfessorX Charles Xavier]] is a kindly old British-American schoolmaster, that ComicBook/{{Magneto}} is a grey-haired old man named "Erik Lehnsherr", that ComicBook/{{Wolverine}} is a TallDarkAndHandsome loner, and that ComicBook/{{Mystique}} is Magneto's loyal female minion.[[note]] In the comics, Rogue is a sexy and confident [[HeelFaceTurn former supervillain]] who could [[FlyingBrick fly and punch through walls]] for most of her history, Charles Xavier is a fully ''American'' political activist with a strong manipulative streak, Magneto is a young and muscular [[WhiteHairBlackHeart white-haired man]] named "Max Eisenhardt" ("Erik Lehnsherr" is one of his many aliases), Wolverine is a scruffy-looking loner who's often the butt of jokes for [[TheNapoleon his short stature]], and Mystique is a [[ChronicBackStabbingDisorder treacherous and slippery]] spy and assassin who led her own supervillain team for most of her history.[[/note]]

* CantUnhearIt: Several including, Creator/PatrickStewart or Creator/JamesMcAvoy as Xavier, Creator/IanMcKellen or Creator/MichaelFassbender as ComicBook/{{Magneto}}, Creator/HughJackman as ComicBook/{{Wolverine}}, Creator/AlanCumming as ComicBook/{{Nightcrawler}} and Creator/KelseyGrammer as ComicBook/{{Beast|MarvelComics}} to name a few.

** ''Film/Deadpool2'': [[Characters/CableNathanSummers Cable]] is a half-cyborg soldier from the future whose wife and young daughter are murdered by Russell Collins/Firefist, a pyrotechnic supervillain. Cable travels back in time to prevent this from happening with the strong intent to kill Russell when he's still a child. He breaks into the Ice Box, the mutant prison Russell is being held in, and mows down the guards before then fighting [[Characters/XMenFilmSeriesDeadpool Wade Wilson/Deadpool]] and beating him too. Cable then goes after a prison caravan Russell is in while making further attempts to prevent Deadpool's interference as well. Cable then teams up with Deadpool and his friends to track down Russell and after Deadpool sacrifices himself to protect Russell from Cable and thus, undoes Russell's actions in the future. Cable then relives the previous fight against mutant-hating orderlies perfectly while saving Deadpool and deciding to stay to further help preserve the future comfortable knowing his family is alive again.

** At the very least, both franchises have put out their own version of the same characters: ComicBook/{{Quicksilver}}, and the X-Men[=/=]Fox version is generally considered better than the version of the character in ''Film/AvengersAgeOfUltron'' [[spoiler:who was KilledOffForReal by Joss Whedon to give the story some amount of stakes and also because the character became disposable]]. Likewise, the fact that Marvel Comics have responded to Fox holding on to the rights for characters that it has made into commercial successes [[IWillPunishYourFriendForYourFailure by essentially short-changing the X-Men]] in the comics and promoting the ''ComicBook/{{Inhumans}}'' as a SuspiciouslySimilarSubstitute has spurned many long-time fans of the X-Men away from Marvel, while ''Film/{{Logan}}'' was seen as an improvement on the original ''ComicBook/OldManLogan'' story by Creator/MarkMillar.

** In ''Film/XMen1'', Senator Kelly specifically [[MythologyGag mentions]] [[ComicBook/KittyPryde a girl who can]] [[IntangibleMan walk through walls]], and asks "What's to stop her from walking right into a bank vault -- or the White House?" Well...

** ComicBook/{{Cyclops}} is the leader of the team and main character in many of the comics, but he's DemotedToExtra in ''Film/X2XMenUnited'' and [[spoiler:killed off within a few scenes]] in ''Film/XMenTheLastStand''.

** Despite being a prominent female heroine in Marvel, ComicBook/{{Rogue}} past the [[Film/XMen1 first film]] (where she was a LivingMacGuffin) is heavily DemotedToExtra. She only gets a couple of scenes to herself, in which she mainly laments over the [[IJustWantToBeNormal uncontrollable nature of her powers and how they have been negatively affecting her relationship with Iceman]]. This subplot concludes in ''Last Stand'' with her taking the mutant cure off-screen, and she doesn't even get to join the remaining heroes in the climactic final battle against Magneto's Brotherhood.
** ComicBook/{{Jubilee|MarvelComics}} is generally one of the most iconic and celebrated characters in the X-Men, but the original film trilogy reduced her to a background character who doesn't speak. ''Film/XMenApocalypse'' managed to give her a speaking role and even have her tag along with Cyclops, Jean and Nightcrawler to the mall, but it isn't much more than a cameo and she gets capured by Stryker shorty after and isn't part of the FinalBattle.

* WTHCastingAgency:
** This likely ''would'' have happened in the solo ''Gambit'' movie, with the title character [[http://www.ign.com/articles/2014/05/13/channing-tatum-confirmed-as-gambit having been Darrin'd from]] Taylor Kitsch, who previously portrayed the character in ''Film/XMenOriginsWolverine'', to Creator/ChanningTatum as he looks and sounds nothing like the character in question. And even if the role was going to go to another actor, fans seem to prefer a more convincing one for the part like [[Series/{{Lost}} Josh Holloway]] or French actor Gaspard Ulliel. The film languished in DevelopmentHell and eventually was shelved.
** The casting of Creator/HenryZaga as Sunspot and Creator/AliceBraga as Cecilia Reyes in ''Film/TheNewMutants'' has led to considerable backlash and accusations of whitewashing. Although Zaga is from Brazil, Sunspot is ''Afro''-Brazilian, and his origin specifically has him being discriminated against for his African features. Likewise, Reyes is Afro-Latina. Both Zaga and Braga are not black (being olive-skinned and light enough to appear somewhat white under some shades). The reaction to Braga's casting is further fueled by the fact she is replacing the much better-received Creator/RosarioDawson, who had to drop out due to scheduling conflicts with ''Series/LukeCage2016''.

* SeinfeldIsUnfunny:
** The first two ''X-Men'' movies have largely been overshadowed in the mid-to-late 2000s by the ''Film/SpiderManTrilogy'', ''Film/TheDarkKnightTrilogy'', and, of course, the Franchise/MarvelCinematicUniverse, but at the time, the [[Film/XMen1 first movie]] was a surprise hit that proved vital in convincing Hollywood that {{superhero}}es could be viable again after ''Film/BatmanAndRobin'' had [[GenreKiller killed the genre several years earlier]]. People tend to forget that alongside ''Film/{{Blade}}'' and even the divisive ''Film/{{Daredevil}}'', the original ''X-Men'' films were massively influential in terms of tone and costuming, arguably becoming the TropeCodifier for MovieSuperheroesWearBlack (although Creator/TimBurton's ''Film/{{Batman|1989}}'' can claim that as well).
** Also, up till then, superhero films tended to be star-driven vehicles in order to avoid a perceived comic-book ghetto; you needed a $20-million headliner like Creator/JackNicholson, Creator/ValKilmer or Creator/WesleySnipes to pull in a mass audience, and ones that didn't, like ''Film/{{The Phantom|1996}}'' and ''Film/TheRocketeer'', got destroyed at the box office. Here, the two biggest under-50 names were Creator/HalleBerry and Creator/AnnaPaquin, both supporting characters (and both ''women'') and two of the three central leads were played by aged Shakespearean actors, while the other was an Australian unknown in Hugh Jackman. Nowadays, especially in the TurnOfTheMillennium and TheNewTens movie landscape where star vehicles have given way to ensemble pieces driven by premise and spectacle, superhero films have few qualms about casting [[Film/{{Thor}} unknown actors]] or [[Film/GuardiansOfTheGalaxy2014 actors who had never headlined a blockbuster before]], knowing that the property will sell itself and the movies will propel the actors to further heights instead of the other way around.
** The films also showed superheroes with powers and skills entirely different from the superhero films made before, showing how unique and special superhero action could be, with many citing Nightcrawler's opening in the second film as a major example of the unique action setups possible only with super-powered characters. Before the only super-powered being (as opposed to BadassNormal like Batman or EmpoweredBadassNormal like Blade) was Superman's FlyingBrick skillset whereas this film showed magnetic, telekinetic, telepathic, teleportation-based powers that hadn't convincingly been shown in movies before.

** ComicBook/{{Storm}} is an iconic black female superhero and generally one of Marvel Comics’s most celebrated leading ladies, however her role in the films left much to be desired, as she was firmly on the sidelines outside of a few scenes where she got to display her powers. Even when Creator/HalleBerry (who is a oscar winner) pushed for a bigger role in ''Film/XMenTheLastStand'', she was still at best only Wolverine’s sidekick. ''Film/XMenApocalypse'' and ''Film/XMenDarkPhoenix'' (where she was recast with Alexandra Shipp) likewise don’t do much with her character, with the former film only characterizing her as a HeroWorshipper of Mystique who becomes an UnwittingPawn of Apocalypse and the latter film reducing her to a side character.

** Despite being a prominent female heroine in Marvel, ComicBook/{{Rogue}} past the [[Film/XMen first film]] (where she was a LivingMacGuffin) is heavily DemotedToExtra. She only gets a couple of scenes to herself, in which she mainly laments over the [[IJustWantToBeNormal uncontrollable nature of her powers and how they have been negatively affecting her relationship with Iceman]]. This subplot concludes in ''Last Stand'' with her taking the mutant cure off-screen, and she doesn't even get to join the remaining heroes in the climactic final battle against Magneto's Brotherhood.

** ComicBook/{{Jubilee}} is generally one of the most iconic and celebrated characters in the X-Men, but the original film trilogy reduced her to a background character who doesn't speak.

** In the prequel films, none of the characters age much across the several decades, which some fans handwaved as a result of them being mutants. However, Moira threw a wrench in this fan theory due to her being a baseline human who also didn't age at all between the 60s and 80s... which makes the retcon in the ''[[ComicBook/XMen2019 House of X]]'' comics that she's not only a mutant herself, but an exceptionally powerful one as well, an amusing reveal. Now the mutant aging fan-theory has no holes!
