That looks fun. John Cena is so popular because he's cool and he makes good movies. (plus, I've heard he's a really nice guy) Also, I geeked out a bit seeing Christian Slater. Even if it's a supporting role, it's nice to see him in a new movie.
Don't get me wrong, he's good at what he does, over the top action movies..... I don't hate the guy, I'm a wrestling fan and his character there has grown on me somewhat, it's just that his movies aren't generally my thing.
