He's a cool actor, the problem I find is that he isn't acting in the movies that he should be in. He is in family friendly movies when I would much rather be the next epic action-movie star. Scorpion King was fun, for example.
But the new movie got bad reviews, it is supposed to suck. Also, I think that some way, some how, he is going to mess up at the KCA. Also, doesn't him hosting it seem like a big advertisement for the movie? Like Jack Black had Kung Fu Panda, a great movie coming out, and he was host. The whole KCA is self-advertisement.
