History YMMV / Ultimatum

* CatharsisFactor: After causing worldwide destruction and the deaths of many beloved characters, nobody complained when Magneto dies courtesy of Cyclops burning his head off. It was even more cathartic in its day if you had been following ''ComicBook/UltimateXMen'', as he has had his own share of terrible crimes during that run.
* HarsherInHindsight: Thing kills Dr. Doom because he feels Reed doesn't have it in him to do it. Years later, this exact Reed becomes a genocidal villain that even manages to escape the Ultimate Universe and terrorize the mainstream Marvel Universe.

* {{Squick}}: The scene of Blob eating the Wasp's corpse.

** The random deaths, all gory, become sort of funny after a while.
** One of Wolverine's lines to Magneto during their fight? "I got news for you -- if you're God, then God is dead!"

* AudienceAlienatingEra: Almost universally agreed to be this for the Ultimate Universe, due to taking DarkerAndEdgier UpToEleven and killing off several characters.

* DorkAge: Almost universally agreed to be this for the Ultimate Universe, due to taking DarkerAndEdgier UpToEleven and killing off several characters.

* CriticalResearchFailure: The comic interchangeably says that Magneto has offset the Earth's axis and its magnetic poles. The Earth's axis has nothing to do with magnetism. And even if they were, all of the results of his actions, including the massive flooding of New York City, couldn't be caused by manipulating either the magnetic polls or the Earth's axis.

* WhatAnIdiot: Once the heroes get to the base, there are two tasks: destroy Magneto's machines, and kill Magneto himself.\\
'''You'd expect:''' That Iron Man, whose suit is made of metal and thus vulnerable to Magneto, would be sent to destroy the machines, and that the awesome power of Hulk would be targeted against Magneto.\\
'''Instead:''' They do things the other way. Iron Man is controlled by Magneto, who uses him to kill Wolverine, while Hulk is busy elsewhere.

* FunnyAneurysmMoment: Thing kills Dr. Doom because he feels Reed doesn’t have it in him to do it. Years later, this exact Reed becomes a genocidal villain that even manages to escape the Ultimate Universe and terrorize the mainstream Marvel Universe.

* UnintentionallyUnsympathetic: Sue Storm calling Reed out on abandoning her is meant to be a WhatTheHellHero moment calling Reed out for being too logical and not caring for his loved ones. The reason Reed abandoned her was to ''save the entire world'', making Sue come across as extremely narcisistic to believe that Reed should prioritize her over the world.

* OvershadowedByControversy: Creator/JephLoeb's decades-long career was overshadowed by a highly visible CreatorBreakdown he underwent in the late 2000s following the sudden death of his son. Not only did the overall quality of his writing take a hit during this period, but his stories would frequently deal with disturbing topics such as incest and display a level of violence unusual for the superhero genre. In particular, he wrote ''ComicBook/TheUltimates 3'', which was not up to the quality of the first two miniseries written by Creator/MarkMillar. It was followed by this story, a CrisisCrossover that killed half the cast of the ComicBook/UltimateMarvel universe, mostly in gruesome ways. He has written several other comics: ''ComicBook/TheLongHalloween'' (two Eisner Awards), ''ComicBook/DarkVictory'' (one Eisner Award), ''ComicBook/SupermanForAllSeasons'' (two Eisner nominations, one Wizard Fan Award), ''ComicBook/BatmanHush'', ''[[ComicBook/TheDeathOfCaptainAmerica Fallen Son: The Death of Captain America]]'', etc. He also created the characters ComicBook/XMan, ComicBook/RedHulk, Sam Alexander and Jimmy Hudson, all of whom, although divisive, have been fairly prominent at times. And even in the Ultimate line, he also wrote follow-up work such as ''New Ultimates''. Still, for many fans he's the one who ruined the Ultimate line with ''Ultimatum'', and nothing else. Eventually, he decided to work in TV full-time.

* HarsherInHindsight: Blob and Wasp fought against each other in ''Ultimates 3'', and Blob said that he would eat her. It seemed like mere battle bravado at the moment.

* SoBleakItsBoring: The comic was so bleak that many readers either swore off the Ultimate Marvel continuity or were discouraged from getting into it. It doesn't help that an interlude features a dead pool ([[ComicBook/{{Deadpool}} not that one]]) suggesting the whole thing is nothing to be concerned about.
