Honestly, Fassbender's Magneto is the single best representation of a supervillain ever from comic to screen. Even Ledger's Joker wasn't that close to the comics, but Fassbender embodies everything there is about Magneto. His tragedy, his philosophy, his attitude, and his ruthlessness. Some people kind of think that he's a nice guy who is just misguided, but Days of Future Past shows that he's not a nice guy by just incredibly ruthlessly trying to kill Mystique right in front of her brother (who is also his best friend) and not thinking twice about it.
Really this scene from First Class just embodies the character: LINK
