Ok, I'll be honest - I fuckin' hate superhero comics and ESPECIALLY dislike super hero teams like the justice league, the avengers, the whatevers and so on. I'm not saying you can't have deep and serious stories with guys who dress up in colorful costumes (but it IS pretty damn hard), but for the most part any comic I even glance from such a franchise is just a pile of usually good art, impossible to follow continuity and way too often - an absurdly stupid plot. That and for the most part a lot of stories end up being moot, since in the next series that features these characters, it's either ignored, retconned or just never mentioned.
With all that out of the way - I am completely with MovieBob on this whole thing being completely awesome. Like I said, I hate the fact that most super hero comics don't seem to go anywhere, but having several movies all build up towards another one? Yeah, that's just kick ass. Now if only people would learn from this and start making other movies this way.
...shit, my entire post is just rambling. I should be in bed.
