This is the promised X-men: Origins: Magneto, announced with the Wolverine movie. He’s the person most in focus and goes through the biggest character arc.
Recasting everyone is similar to a new creative team taking over a comic. The art looks different, the continuity may shift, but there’s core parts that remain the same. Wolverine: Origins did the same, but nobody cared.
This team was a lot of fun. It's a shame they killed them all off. This is a problem comics don't have to deal with because A) Actors don't leave comic books and B) Dead in comics is a minor inconvenience.
There was a time when Wolverine was not a member of every team in the Marvel universe, and not guest starring in every single comic. He did not have his own brands of clothing, school gear, and toilet paper. Wolverine was created in 1974 and his first solo publication didn’t happen until that excellent four issue series in 1982.
The train fight. WOO! That is all.
Not sure who did the "didn't know there was a pool" gag first, but it's always funny.
There is another thing
that feels off that changing the order from the comics.
Having Mariko be how Logan comes to terms with Jean’s loss was a little
weird. Their relationship was really
well done in the comics, and him trying to be a samurai and “calm the beast
within” for her would have been nice to experience on screen. That relationship happened in comics well before the "unrequited love for Jean" became less of an aside, and more of a character defining trait.
Seeing this version of Yukio, who was awesome wielding a sword or snowplow, come back would have been welcomed.
Instead of a true “Days of Futures Past,” it’s a continuation of Magneto’s origin story, plus bits from the “Old Man Logan” in the more recent Marvel Universe books.
There are multiple other set ups and pay offs, and the holidays in the “Calendar Girl” song match up exactly with the montage scenes.
