I have no big problems with Observe And Report, but, I don't know, have you watched The League Of Gentlemen/Psychoville? The film's neither that clever nor that daring.
Zombieland wasn't funny. Emma Stone was a bitch in it and it was totally underwhelming after all the hype it got. People were saying it's better than Shaun of the Dead.
No, it most definitely isn't. I don't see how anyone could enjoy a movie that basically consisted of two girls acting like bitches, being rescued by the main guys, and then ripping them off and running away OVER AND OVER
