Fassbender continues to add great intensity to the franchise here. It's not hard to see why he is many people's favourite thing about this generation.
... I just wished I liked his story more.
Like Lawrence's Mystique, it feels like Singer is struggling to contrive reasons to bring everyone together again. There's not a lot left to learn from putting Erik and Charles together, so it feels a lot like the film just moves them about on the board to make the same story feel new again.
He starts out good here, then goes bad, then goes good again, so that's different, cause normally he's bad, then good, then bad. Meh. I've heard complaints about repetition before, but it was only here when it started to crumble to me.
Unlike Mystique though (who is back and still freeing captive mutants) this Magneto story doesn't even seem like a logical progression from DOFP. It's like a film is missing in the middle, that would presumably explain how he went from rallying mutant forces to settling down with a wife and kid. It's quite a jarring leap on its own, however it is ultimately sunk by the fact that you know from the first shot that this perfect family are canon fodder.
So he gets a new villain origin story of sorts, which is less interesting than the first and doesn't add any new layers to his character. It solely exists to justify his decision to side with Apocalypse, who will exploit his sadness and nothing else. This is already a waste, as it glosses over Erik's own world view. He isn't acting for a reason. He is grieving. Erik then overwhelms the other horsemen who could have had stories of their own.
A strong performance can only carry things so far. I think Magneto is a huge problem with this film, and it may have fared better without him.
It's VERY believable that in this new timeline Charles respects Erik and also wants to find a way to redeem him. He's not a villain like he was in the 2 Timeline Primes.
First Class: he was an X-Man.
DOFP: he was sealed in a prison because he had been framed. Then, he just tried to kill the President and wipe out the whole Sentinels program.
Apocalypse: he had lost his family (murdered). He was under the influence of Apocalypse; Oscar Isaac confirmed it was the power of persuasion in play, because En Sabah Nur gets this power.
In the end, Magneto turns into an X-Man again and helps the guys to kill Apocalypse.
What's the problem?
The problem is that he is a mass murderer. He's not the villain presented in the OT, you're right. He's killed many more people this time around.
-FIRST CLASS-
He was an X-Man in First Class until he decided to kill the villain and persue his mission for mutant dominance. At this point, Charles saw that the two do not want the same thing.
-DOFP-
"Just" tried to kill the president? How is that a "just"? Charles reluctantly teams with Erik here only to be imediately betrayed again when Erik turns to murdering Mystique to save the day. Erik then attempts to assassinate the president in a public display of mutant supremecy.
-APOCALYPSE-
A tragic incident does not excuse global genocide. Charles might always try to tap into the good side of Erik, but it is just bonkers to think that the pair bid farewell on good terms after Erik nearly destroyed the world out of grief and Apocalypse cool-aid. Charles handed Erik over to authorities in X1 for much less, for good reason.
