I just got back from it and I really enjoyed it. I had forgotten how much Kick-Ass is a freaking blast. The film is still really funny, the action is violent as hell, and the performances were great. After for the alterations to the darkest scenes, I will say they did a really nice job with them.
There was one change I didn't care for and that had to do with the location of the final battle. I'm sure that had to do with the budget more than anything though.
And hey, Jorah Mormont pops up! Clean-shaven, he looks a lot like a younger Jack Nicholson.
