First of all, I don't like comic books and it seems that every second movie nowadays has to be based on one, featuring guys in Dorky suits with superpowers. No wonder I liked "Kick-ass".
Second, the Batmans are the only ones I kind of like and I like Bale as well. However, given that he's wearing a mask half of the time, does it really matter that much that it's Affleck now? I really don't think so.
