I'm sure. But it just seems to me like none of the major players ever really die. I'll admit I don't really know all that much about comic books, but the impression I get is that a whole bunch of these superheroes are killed only to be brought back later. If they don't stay dead, where's the threat? Even if they get killed, you know they'll be back. It totally undermines it for me.
Take the latest X-Men films. I honestly thought killing off Xavier was a seriously ballsy move in the third film, and it impressed the hell out of me. But now he's back. And they didn't even explain it.
