History YMMV / XMenDaysOfFuturePast

** Before the movie's release, Evan Peters' portrayal Quicksilver was already being highly criticized for a) not being the same as Aaron Taylor-Johnson in ''Avengers: The Age of Ultron'' and b) his costume, which many called ridiculous. When the people got to see him in the film, the public's opinion of him changed radically after the [[OneSceneWonder Pentagon kitchen scene]].

* HypeBacklash: The film is hyped as being both a return to form for the X-Men films, mitigates all the troubling qualities of the previous installment, and is said to be as good as the Franchise/MarvelCinematicUniverse films; in other words, its very, very hyped up. For some, it really doesn't live up to it, especially those who still see many of the same issues as before creeping in.

** The decision to make Wolverine the main character of the storyline when Kitty Pryde was in the comics. It makes more sense with the movie series's established plotline (Wolverine is sent back via MentalTimeTravel to the 1970's and Kitty hasn't been born yet), but it's still a bitter pill for Kitty fans and people who wanted to see another X-Men movie where Wolverine was NOT the main character. Of course, it also goes in reverse; many fans who have stuck with the series since the release of ''X1'' have argued that the film would have had a ''drastically'' reduced emotional impact if we had Kitty instead of Logan, seeing as how little screen time she had in the previous movies. [[spoiler:Although Logan's role in the movie is fairly minor; in the 1970's, he takes a backseat to Charles, Erik, and Raven.]]

** As with Creator/{{Sony}}'s ''[[Film/TheAmazingSpiderManSeries Amazing Spider-Man]]'' films, many fans of the Marvel Cinematic Universe criticized this film just for existing and maintaining {{Fox}}'s hold on the X-Men film rights, since they wish the rights would go to Marvel Studios (as they would eventually in 2017). All the more since the Marvel Cinematic Universe version of Quicksilver had already appeared in ''Film/CaptainAmericaTheWinterSoldier'' and later in ''Film/AvengersAgeOfUltron''. And then there were accusations of Marvel trying to undermine Fox's success by downplaying its ''ComicBook/XMen'' marketing in the comics and cancelling its ''ComicBook/FantasticFour'' titles, while playing up lesser-known concepts such as the ComicBook/GuardiansOfTheGalaxy and especially the Inhumans. Given that most of these franchise's box office draw comes from movie goers and not comic fans, however, one has to wonder how people got this assumption.

** Bishop in particular. He is a rather popular character (almost like a mini-Cable), especially having been the character sent back in the 90's animated adaptation of the storyline ([[MythologyGag which is presumably why he is the first character seen using the travel]]). In the only film to deal with one of the x-men's many potential future timelines, he simply serves as one of many [[RedShirts red shirt heroes]].

* EvenBetterSequel: While ''First Class'' was well-liked by fans for bringing the ''X-Men'' series back on track, ''DOFP'' has been even more well-received and cited by a few reviewers as the best of the ''X-Men'' movies. It even currently has the highest Rotten Tomatoes score in the series at 91%, placing ''DOFP'' among the best-reviewed Marvel movies of all, Franchise/MarvelCinematicUniverse or otherwise. The movie has also become the top-grossing ''X-Men'' film in terms of worldwide box office by far, usurping the position previously held by ''[[Film/XMenTheLastStand The Last Stand]]''.

** As with Creator/{{Sony}}'s ''[[Film/TheAmazingSpiderManSeries Amazing Spider-Man]]'' films, many fans of the Marvel Cinematic Universe criticize this film just for existing and maintaining {{Fox}}'s hold on the X-Men film rights, since they wish the rights would go to Marvel Studios. All the more since the Marvel Cinematic Universe version of Quicksilver had already appeared in ''Film/CaptainAmericaTheWinterSoldier'' and later in ''Film/AvengersAgeOfUltron''.

** Note that this MCU rivalry is different for ''X-Men'' than for ''The Amazing Spider-Man'' (which has a FandomRivalry with ''DOFP'' in its own right). Due to ''DOFP'''s very positive reception, the rivalry is less "they're turning the series into a FranchiseZombie [[AshCanCopy just to hold on to the rights]]"[[note]]a criticism of ''Film/TheAmazingSpiderMan2'' by [[BrokenBase some fans]][[/note]] and more "which Marvel movie series/universe is better".[[note]]If you want to get technical, it's also often argued that the concept of X-Men works better in their own universe, since it wouldn't make sense why the Avengers are so respected yet mutants are segregated and hunted -- a reason why Simon Kinberg has [[FlipFlopOfGod stated that]] ''Film/FantasticFour2015'' won't take place in the ''X-Men'' universe.[[/note]]

** A small one, but this film explains how Hank could be Beast in ''Film/XMenFirstClass'', but appear human on TV in ''Film/{{X2| XMen United}}'', and how Xavier could have the use of his legs in ''X3'' and ''Origins''. (Except that taking the serum cancels Xaviers powers, yet in those films he walks and uses his powers at the same time).

* HarsherInHindsight:
** The final scene in ''Film/XMenFirstClass'' (in which the young Magneto begins his StartOfDarkness by rescuing Emma Frost and giving his nickname for the first time) seems a lot more grim when you realize that most of the people standing in the room with him (save for Mystique) [[BusCrash died offscreen between films]], and no one besides Erik or Mystique giving a damn about their deaths.
** In ''Film/XMen1'', Mystique injected a substance into Cerebro that was either meant to put Xavier into a coma or kill him. Now that old Xavier himself confirms that he and Mystique grew up together, it turns her actions in the first film into a cruel betrayal. Mystique had fallen so low that she had no emotional problem with putting her adoptive brother into a coma and possibly killing him just to further an agenda.
*** However, this is one of many things that may now no longer have happened due to the CosmicRetcon.
*** She may have had an emotional problem. Someone with her abilities could have used a much more lethal poison, or a bomb, to ensure that Xavier dies. Instead, Mystique used a drug which the professor would have a fair chance of surviving.
** When Erik offers to play chess as a peace offering to Charles during the plane ride to Paris, it's not just because he feels guilty for losing his temper earlier, but he knows that this is his last chance to bond amicably with Charles before [[spoiler:carrying out his plan to murder Mystique]]. If it were successful, Xavier would ''never'' forgive him for [[spoiler:killing his beloved sister]], so Erik believed at the time that he'd lose ''any'' hope of reconciling afterwards.
** Professor X's line "Experimentation on mutants--it's not unheard of" in ''Film/XMen1'' becomes more chilling when you take into account Bolivar Trask's examination and dissection of mutants in this movie. Xavier would be thinking more specifically of [[spoiler:Banshee's death and the torture Mystique endured before she managed to escape Trask Industries in the original timeline]].
** When Bobby informs Logan in ''Film/X2XMenUnited'' that there is no beer at the school, it's obviously because Professor X doesn't want to encourage underage drinking, but there is an additional reason for the alcohol-free environment. This installment reveals that Charles was a drunkard in between 1963 and 1973, so naturally his older, wiser self doesn't want to be tempted by drink and risk a relapse.
** We learn that Xavier harboured a DarkSecret from his childhood (i.e. mistaking the onset of his telepathy at age nine for a severe mental illness). While it's hinted in ''Film/XMenFirstClass'' that his mother is an innately cold person, at least some of her aloofness can be attributed to the ''very'' strong stigma which existed around psychiatric disorders in the 1940s. No wonder Raven was Charles' oldest ''and'' only true friend--she was the ''sole'' individual in his social circle who didn't consider to him to be a "lunatic" because he heard voices in his head.
** Near the end of ''Film/X2XMenUnited'', Stryker's grave warning is, "One day, someone will finish what I've started!", and mutant genocide actually does become reality in this movie. The colonel wasn't making an empty threat ''at all''; he was plainly aware of Trask Industries' progress on the Sentinels, and he knew it was only matter of time before the robots were sophisticated enough to slay even the most powerful mutants.
** In ''The Rogue Cut'', Ms. Maximoff is seen consuming alcohol while watching TV in the middle of the day; in ''Film/XMenApocalypse'', she's holding a drink during daytime while talking to her son Peter. It's bad enough that Quicksilver grew up without a father; living with an alcoholic mother definitely can't be easy. One of the reasons why Ms. Maximoff is [[DrowningMySorrows drowning her sorrows]] is because she's bitter at Erik for abandoning her before Peter's birth, which would've been in the mid-1950s, when unmarried women with children were treated like social pariahs.

* HilariousInHindsight:
** The comic book crossover between the X-Men and the cast of ''Series/StarTrekTheNextGeneration'' had members of both cast having to deal with interferences to the Battle of Wolf 359 and Days of Future Past. Captain Picard was among those arriving in the [=DoFP=] timeline, technically making it Stewart's first experience in a world dominated by Sentinels.
** The parents of Bobby Drake were horrified in ''Film/X2XMenUnited'' when they thought that Wolverine was a teacher at the mansion (which was just Wolverine's convenient excuse at the time). Now, he ''is'' a teacher, for real. And who says that Bobby was not one of his students?
** The reaction to Quicksilver, in a manner largely unrelated to the issues with his upcoming appearance in the Avengers sequel; many took exception to what appeared to be terrible visuals for the character when some of the still photos and character shoot images were revealed, and stated that they would wait for Whedon's sequel for a 'true' take on the character. Cut to the film's release, and it looks like Whedon actually has a pretty high benchmark to meet, given Singer's Quicksilver has been embraced by the audience.
** A DeusExMachina allows Creator/PatrickStewart's Professor X to act as SpiritAdvisor to Creator/JamesMcAvoy's young Charles Xavier, which is ''precisely'' what happened when both actors were in ''WesternAnimation/GnomeoAndJuliet''!
** Considering that Xavier can [[spoiler:easily use Magneto as a marionette as long as the latter doesn't wear the telepathy-blocking helmet]], his words of encouragement in ''Film/XMenFirstClass'' ("When you can access all of that, you will possess a power no one can match. Not even me") now sounds rather hollow. It comes off as a little white lie that he made up on the spot in order to try to help Erik achieve the correct point between rage and serenity. In their natural state, Charles' ability is stronger than Erik's, no ifs, ands or buts about it. ''Film/XMenApocalypse'' further reinforces this point by depicting Professor X as the second-most powerful mutant in the story after Apocalypse [[spoiler:(third after Jean releases the Phoenix Force)]], and the eponymous villain waxes poetic about Xavier's psychic powers, calling them "extraordinary" and the best gift that he had encountered in "a thousand lifetimes."
** Warpath DualWielding daggers against the giant Sentinels, with a boost from Blink, [[Manga/AttackOnTitan and goes for the neck.]]
** It's implied in a later scene that Hank is a {{Trekkie}}, so calling Peter's power "fascinating" was his attempt to emulate Spock, who is presumably his favourite character on ''Series/StarTrekTheOriginalSeries''.
** ''Film/MadMaxFuryRoad'''s Slit is Stryker, which is hilarious considering that Nux is Beast.
** Anyone who is a fan of both [=McAvoy=]'s Xavier and Will Graham from ''Series/{{Hannibal}}'' will notice the striking similarities between the two characters. (You can read a more detailed comparison in the ReferencedBy section on [[Trivia/XMenFilmSeries this page]], but for the sake of this entry, it's enough to know that Will is a [[TheEmpath "pure empath"]] who is physically and emotionally scarred by his abusive love-hate relationship with the murderous Hannibal Lecter--heck, Hugh Dancy and Creator/JamesMcAvoy even look somewhat alike.) The ''Film/XMenFilmSeries'' fandom coined the term "Mutant husbands" to describe Charles' and Erik's homoerotic friendship, so all Cherik shippers who had watched the ''Series/{{Hannibal}}'' episode "And the Woman Clothed with the Sun..." burst out laughing when Freddie Lounds called Graham and Lecter "Murder husbands."
** Six years after ''Film/{{Wanted}}'', Creator/JamesMcAvoy accuses someone else for committing assassination because the bullet curved.
** The fact that Creator/PeterDinklage portrayed Bolivar Trask is a lot funnier now that his ''Series/GameOfThrones'' co-star Creator/SophieTurner plays the young Jean Grey in the next film.
** The younger Professor X and Bolivar Trask once worked together in ''Film/{{Penelope}}''.
** The reason why Stryker can tell that "Wolverine" is an impostor in ''Film/X2XMenUnited'' is because the former had a scuffle with Mystique in 1973 when she freed mutant soldiers who were meant to be transported to Trask Industries. Stryker had witnessed firsthand her shape-shifting abilities.
** Anyone who watches ''Days of Future Past'' before ''Film/WorkingGirl'' would chuckle whenever the characters in the latter discuss Trask Industries.
** Although ''Series/Legion2017'' takes place in a parallel universe which is distinct from the movie-verse, the show nevertheless alludes that David Haller is vaguely connected to Professor X (the former is the latter's estranged son in the comics). David also assumes he's going crazy when his mutant ability first manifests because he's HearingVoices. Both characters also sport MessyHair to denote their psychological instability.

* {{Narm}}:
** Magneto [[spoiler:names the mutants who have died when he lashes out at Professor X for the latter's apathy and inaction. But it falls rather flat when -- except for Sean Cassidy -- ''every character'' he mentions supported Sebastian Shaw, the villain in ''First Class'', in his nuclear winter plot, and had attempted to kill/successfully killed Xavier's proteges.]] Xavier has little reason to mourn for their loss, ''or'' feel regret that he didn't help to save them. There's also the matter of Magneto's colossal back-stabbing mitigating any right of his to criticize the Professor for how he lived after being abandoned on the beach.
-->'''Logan:''' ''So you were ''always'' an asshole.''
** The future Sentinels dispatch their enemies in such hilariously over-the-top ways that it can be hard not to snicker.
** At one point, a character ([[spoiler:Mystique]]) screams "Get out of my head, Charles!" when Professor X is trying to reach said character. While the scene it's in is dramatic and well-acted, the Narm kicks in if you have seen "[[WebVideo/MyWayEntertainment The Juggernaut, Bitch!]]", in which that line is one of Juggernaut's many catch phrases.
** There's only so many times you can stand dramatically in one place, arms out, palms up, while stuff just floats around you before it becomes silly. This goes for Magneto and [[spoiler:Apocalypse]].
** Also, Magneto's aerial propulsion onto a train towards the beginning of the third act via pelvic thrust.
** When Wolverine grabs Charles and says "Listen here, you little shit," the filmmakers couldn't have known this, but it's something of a meme phrase. It's very easy to mentally auto-continue: "[[http://knowyourmeme.com/memes/navy-seal-copypasta I'll have you know I graduated top of my class in mutant school, and I've been involved in numerous secret raids on the Brotherhood...]]"
** The Army Colonel Mystique impersonates [[WhatTheHellIsThatAccent sounds]]... [[VocalDissonance odd]].
** Creator/JamesMcAvoy is a great actor and can bring a lot of intensity to his lines. Perhaps too much at times. Like "So...Much...Puh-AIN."
** For anyone who understands Vietnamese, Mystique's scene with the VN general was ridiculous; she spoke with a heavy, barely discernible accent, and yet he praised her as if she spoke like a natural. Of course, he ''was'' currently trying to get into her pants at the time....
** "What's the matter baby? You don't think I look pretty like this?" Cue a lot of snarky comments that Creator/JenniferLawrence in blue makeup is still hot no matter what the film says.

** Bolivar Trask's [[AbilityOverAppearance dwarfism]] in this film has cast his antagonism of the mutant race in this light for some viewers. He either admires mutants and just sees them as a means to an end for protecting Earth, or he hates that he was born with a perfectly ordinary and useless mutation while all other mutants win some form of SuperPowerLottery. Note that this is an interpretation Creator/PeterDinklage and Creator/BryanSinger disagree on; Singer brought the theory up as a possibility, while Dinklage was strongly opposed (as he should, the man has made [[AbilityOverAppearance "not playing a dwarf"]] his life's ambition). And to the movie's credit, no one ever really mentions or even seems to ''notice'' that Trask is a dwarf (except maybe that one senator during the first congress hearing who subtly compares him to a Neanderthal). If he were played by a non-dwarf actor, almost nothing would need to be changed).

** Quicksilver appears briefly to help break Erik out of prison, being both marvellous and hilarious in the process.

* StrawmanHasaPoint: The film presents the inverse of the situation seen in ''[=X1=]''. This time, it's the government who takes the side of the mutants at Trask's Senate hearing and refuse to give the funding he needs to create the Sentinel program. The problem is that Trask has very well-founded fears that the audience can sympathize with. He correctly points out that the U.S. and Russia nearly went to war in the course of a single battle as a result of mutant intervention (which they officially deny, but are later seen to have removed several pieces of clothing and technology from and stored). After the Paris Peace Accord incident, he then points out that the participants include a man who can direct metal (and is the prime suspect/convicted prisoner in the death of a sitting U.S. President), another who believes that mutants will drive humanity into extinction, and a third who can shapeshift into anyone and order a nuclear strike if she felt like it. It doesn't justify his genocidal tendencies towards mutants, but there are some very real fears.

* TheyWastedAPerfectlyGoodPlot: At the end of the film, [[spoiler:pre-Adamantium Wolverine is shown being dredged out of the Potomac River and released into Stryker's custody. Only it's not ''actually'' Stryker, but Mystique in disguise. Stryker getting his hands on Logan in such a manner would have been the perfect way to maintain the connection between their characters and subject him to Weapon X.]]

** The conversation between the younger and older Professor X.
** Peter's BulletTime run through the Pentagon kitchen.

** Every kill from the Future Sentinels.

** Some reviewers of ''The Rogue Cut'' thought the new scenes helped flesh out the story and characters, while others saw them as {{Padding}} that ruined the pace.

** [[Heck, the entire movie becomes this with the reveal that mutant-kind has been dying out in ''Film/Logan''.]]

** In ''Film/XMen'', Mystique injected a substance into Cerebro that was either meant to put Xavier into a coma or kill him. Now that old Xavier himself confirms that he and Mystique grew up together, it turns her actions in the first film into a cruel betrayal. Mystique had fallen so low that she had no emotional problem with putting her adoptive brother into a coma and possibly killing him just to further an agenda.

** Professor X and Bolivar Trask once worked together in ''Film/{{Penelope}}''.

** Wanda Maximoff / Comicbook/ScarletWitch is reduced to a baby MythologyGag rather than exploring her as a character and relationship with Quicksilver and Magneto.
** With Banshee's sudden death between ''First Class'' and this film, he can't possibly be the father of Siryn like in the comics.

** Although ''Series/Legion2017'' takes place in a parallel universe which is distinct from the movie-verse, the show nevertheless alludes that David Haller is vaguely connected to Professor X (the former is the latter's estranged son in the comics) because David also assumes he's going crazy when his mutant ability first manifests because he's HearingVoices.

* MoralEventHorizon:
** If Erik hadn't crossed it before, it's definitely when [[spoiler:he orders the Sentinels under his control to "do what [they] were built to do." Not only is he willing to murder other mutants, he also just ''doesn't care'' beyond his moral agenda. Granted, he did do some morally questionable stuff in the earlier films (such as, for example, [[Film/X2XMenUnited turning Stryker's planned mutant genocide on humanity itself]]), but it's quite clear that he had mellowed considerably since 1973, and the fact that his future self is firmly with the good guys in this film only proves how much he'd matured morally over half a century and is most certainly no small miracle.]]
** Much of the film's plot is built around Charles, Hank, and Logan trying to prevent Raven/Mystique from crossing her (In-universe) MEH of killing Trask. [[spoiler:Erik tries to stop her at first, but tries to push her into murdering humans when her blood is taken anyway.]]
