and I don't get the hate for this movie. It's a good, fun, fast-paced COMIC BOOK movie. Lots of quick cuts and flashbacks but no different than, say, a Bourne flick.
As with ANY ensemble film, some characters were fleshed out and used more while others were not. Radical, right?!?
It is GOOD! Go see it!
if you have any specific questions or thoughts, put em in the comments and I'll be glad to converse with you.
