You're standing on my neck
Yeah, after my nerdgasm finally subsided, I started to think about all the ways it could get screwed up. Not having sentinels, choosing weaker team members, changing the story too much, etc. But really, after the brutal rape of the Dark Phoenix saga (aka X3) I think I can handle anything. I'm not saying I'll automatically like it, but it can't be as soul crushing as X3 was.
That said, I'm still far more excited than cynical. We've had five X-men movies now and none of them have been great in my opinion. So I'm glad they are taking a risk with a major story line.
