Writers have to walk a fine line when they take a former antagonist and turn him into the story's protagonist. I like the idea of giving characters a second chance to redeem themselves but it gets frustratring when a new creative team comes onboard and inevitably reverts the complex character back into a scenery chewing, monologue-spouting, card-carrying super-villain. 
 That thankfully hasn't happened here. Magneto has definitely shed any pretense of being a hero from his run in Uncanny X-Men, but he feels more like The Punisher than Dr Evil. Killing those who persecute mutants, even with the occasional civilian casualty. 
 There is a little bit of backsliding with the comparison to Hitler. I get it the irony, a Jew from a Nazi concentration camp now echoing the one who wanted to wipe his kind out, and it's subtle enough I suppose. It just worries me that it's the first step in Magneto's eventual reversion to super-villain. 
 It's pretty easy to relate to Magneto in this story even if you don't agree with his methods. As an X-Men reader it does get frustrating that no matter what they do they keep getting kicked back down to the ground, treated like dirt. It's easy to understand where Magneto's rage and sadness come from. 
 As long as he remains a three dimensional character with motivations that make sense, I think I'll keep reading this series.
