Before I was able to read a huge number of Batman comics, I was a big fan of the movies. While I still like them, neither of them come close to really portraying my idea of Batman.
Batman is a ying yang character (I hope I used the word right), similiar to Two-Face. One side is Bruce Wayne, this vapid, wealthy playboy. The other is Batman, deep, dark, and determined. A good Batman movie needs to show both. You could argue that some Batman movies hint at these, but I don't think it's even close.
I'm hoping the new Batman movies will reflect this.
Also, let's have a Batman who isn't as slow as a whale for once (in fights).
