History YMMV / XMenFirstClass

* EnsembleDarkhorse: Azazel is one of the Big Bad's minions and has few lines, and yet he's a rather popular character. It's basically due to being Nightcrawler with red skin.

* EvilIsSexy: Scantily clad blonde Hellfire Club member Emma Frost.

* WTHCastingAgency:
** ''Creator/KevinBacon'' as Sebastian Shaw? This crisis was averted with Bacon becoming the physical incarnation of EvilIsCool.
** Creator/JanuaryJones as Emma Frost has also been a polarizing casting choice.

** Kevin Bacon, Sebastian Shaw's actor, is a ''canon'' character in the ''Franchise/MarvelCinematicUniverse'', being name-dropped numerous time in ''Film/GuardiansOfTheGalaxyVol2'' as an idol figure for Peter Quill, and actually making his ''on-screen appearance'' as '''himself''' in the ''Film/TheGuardiansOfTheGalaxyHolidaySpecial''.

* SignatureScene:
** The Cuba showdown.
** Wolverine's cameo.

** "Perfection."[[labelnote:Explanation]]Mystique attempts to seduce Magneto, but he's not impressed until he sees her true form, responding with the above line. The scene led to two related memes, one of which is a comic used to compare various versions of a character or other characters with the [[NamesTheSame same name]], and one of which is a gif of Magneto's line in response to things the poster likes.[[/labelnote]]

* UnfortunateImplications:
** It's been pointed out [[http://4thletter.net/2011/06/x-men-first-class-blue-is-beautiful/ a number]] [[http://www.nytimes.com/2011/06/09/opinion/09coates.html?_r=0 of]] [[http://www.comicsalliance.com/2012/10/01/comicsalliance-reviews-x-men-first-class-2011-part-one/ times]] that this is a movie that tries to use the Civil Rights Era as a backdrop for the emerging mutant struggle... and then kills off one of its leads of color ([[TheWorfEffect whose superpower]] is AdaptiveAbility) and [[FaceHeelTurn has the other turn evil]], leaving the face of mutant liberation to be nothing but white people (Erik is Jewish ... but Michael Fassbender isn't).
** Some have also criticized the movie for its treatment of women; the most obvious criticism is that dozens of women can be found running around in their lingerie, but there's also [[http://hellotailor.blogspot.com/2013/07/the-costumes-of-x-men-first-class-part.html Moira having her memories forcefully removed]] on the one hand and the fact that the original X-men training facility ''[[http://decentfilms.com/reviews/xmenfirstclass exclusively uses female mannequins as targets]]'' on the other.

* MemeticMutation: "Perfection."[[labelnote:Explanation]]Mystique attempts to seduce Magneto, but he's not impressed until he sees her true form, responding with the above line. The scene led to two related memes, one of which is a comic used to compare various versions of a character or other characters with the [[NamesTheSame same name]], and one of which is a gif of Magneto's line in response to things the poster likes.[[/labelnote]]

** Hank, when he bluntly tells Raven that even if humanity accepted mutants, they would never find her blue skin or his big feet as attractive and that she's beautiful only in her human form. He does take a JerkassBall and is surprisingly insensitive towards Raven, but his reaction isn't entirely unforgivable. Physical attraction and self-acceptance are very personal problems, with barely to do with discrimination. Mutants can't be forced to feel good about their own body when their mutation manifests physically, while non-mutants aren't bound to be physically attracted by mutants just because they respect them as people. If Hank is so appalled by his own enormous feet, no amount of "humans finally respect us mutants" can help make him feel better.

* WhatAnIdiot: Moira is fighting against Erik, a guy who she knows can control metal with his mind.\\
'''You'd Expect:''' That she wouldn't [[NoSell fire a gun at him]], given that guns ''shoot metal bullets''. Hell, with the power Erik possesses, he could probably shoot them back at her!\\
'''Instead:''' She fires her gun at him.\\
'''Result:''' He deflects the bullets ''easily''.\\
'''Even Worse:''' Even after Moira sees him deflect the first bullet, ''she keeps shooting'', accomplishing nothing until one projectile accidentally hits Charles.

** ''Kevin Bacon'' as Sebastian Shaw? This crisis was averted with Bacon becoming the physical incarnation of EvilIsCool.
** January Jones as Emma Frost has also been a polarizing casting choice.
* WTHCostumingDepartment: Played straight with the costume Erik wears in the last scene of the film. He has a bright purple cape and modified the helmet so that it's magenta ''and has little horns'', which are straight out of the comics, as seen [[http://4.bp.blogspot.com/-liQr7Sgxobs/TegAbsQSrnI/AAAAAAAAHFc/xNE3MTD0Vr8/s1600/75575-178432-magneto.jpg here]]. The rationale for the costume in-universe is that humans think mutants are spawn of the Devil, so Magneto plays up to it with a red horned costume. In real life, the color scheme was probably chosen because the artists had an extremely limited palette to work with and needed something that contrasted with the X-Men's blue and yellow outfits.

* OneSceneWonder: {{Wolverine}} shows up in one scene. His appearance lasts twelve seconds, in which he says a [[PrecisionFStrike grand total of three words.]] It is one of the most hilarious moments of the film, and Creator/RebeccaRomijn, who equally cameos as a CallForward, admitted she wanted his line.

** It's the opinion of certain fans that Sebastian Shaw shouldn't have been the main villain. They cite the fact that the film version bares almost no resemblance to his comic counterpart, and has more in common with another major X-Men antagonist: Mr. Sinister. Both Movie Shaw and Sinister are long-lived {{Evilutionary Biologist}}s, who experimented on Magneto during their time as a Nazi scientists, and believe Mutants are destined to rule the world. Very different from the aristocratic, Manipulative Bastard, BadBoss, WarForFunAndProfit Shaw of the comics. Using Sinister would've also opened up the possibility of utilizing the more genuinely evil Marauders, instead of wasting the more interesting members of the Hellfire Club, like Emma Frost -- here re-imagined as a one-note DarkChick.

'''Instead:''' She fires her gun at him.

'''Instead:''' He deflects the bullets ''easily'', and one of them hits a bystander.\\

* AssPull: Some find the idea that Raven is Charles' adopted sister to be this given that the two are shown to have no emotional connection to each other in the original movies.

** One of the X-Men featured is Beast. Well, James [=McAvoy=] ''became'' '''the Beast''' in ''Film/{{Split}}''.
** Erik's new helmet at the end made him look like [[WesternAnimation/TheIncredibles Hyper Shock from Project Kronos]].

** Moira had stripped down to her undergarments to sneak into the Hellfire Club. In ''Film/XMenApocalypse'', she does a complete 180° and is covered from head to toe in a niqab to infiltrate En Sabah Nur's cult.

** Hank, when he bluntly tells Raven that even if humanity accepted mutants, they would never find her blue skin or his big feet as attractive and that she's beautiful only in her human form. He does take a JerkassBall and is surprisingly insensitive towards Raven, but his reaction isn't entirely unforgivable. Physical attraction and self-acceptance are very perosnal matters, with barely to do with discrimination. Mutants can't be forced to feel good about their own body when their mutation manifests physically, while non-mutants aren't bound to be physically attracted by mutants just because they respect them as people. If Hank is so appalled by his own enormous feet, no amount of "humans finally respect us mutants" can help make him feel better.

* StrawmanHasAPoint: Magneto ''is'' right, in that his prediction that the US government will eventually turn on the mutants [[spoiler:comes true, and his intention to wipe out the US and Soviet fleets that launched a [[ThereIsNoKillLikeOverkill full barrage]] at them--[[WriterOnBoard overcoming decades of tension in just a few minutes to do so]]--comes off as surprisingly understandable despite its extremism. Xavier, mistakenly, tries to stop him using the "just following orders" defense. Ironically, Magneto's interrupted counter "proved" that mutants in general are a threat. He could've just dumped the barrage he "caught" into the ocean.]]
