I saw it. Here's the thing, I'm not into this latest round of action hero movies. Actually, I was never into comic book heroes at all, not even as a kid.
That said, my brother and other roomate are into this kind of thing, and they also said KICK-ASS had much more serious action parts than they expected, along with comedy. So if you like your action heroes chopping off limbs and watching 20 people die in 10 seconds with bits of I'm in high school kid trying to get laid humor, than by all means, watch KICK-ASS. If the previous sentence does not sound at all appealing, avoid.
