I haven't, but from what I have seen/heard it's not as good as the first. It was a tough first to beat, and from the previews I didn't think it would beat it. I'm still on the KICK Ass bandwagon, and I really suggest it for anyone going to the movies.
I will see it probably in the next few weeks, but from the previews I didn't think it would be as cool as the first. I may be wrong though, anyone else on here seen it? If so, is it as good as the first?
