You would have thought that pretty much everyone in the world knows who Batman is. Sure, you're going to get the people who still think he's the caped crusader from the Adam West show, but I would say the majority of people now associate him with the dark, brooding character we see now.
Well, not the folks at abc Family, whose trailer for Batman Begins seems to be advertising something else entirely. I mean, I guess he sort of "fights for family" in some twisted way, but "lives for love?" Errrm. On top of that, they make it out to be some demented rom-com.
