Bale actually uses a different voice for Batman which already makes it better than any of the other four films in my opinion. Clooney didn't try, Kilmer was alright, and Keaton wasn't much better. I think people like Keaton's Batman just out of some nostalgic attachment. I used to love Burton's Batman but as I watched it more over the years, I realized that it's a pretty crappy movie. It's not very entertaining at all. At least the Schumacher films had camp comedy with Carrey, Jones, Schwarzenegger, Thurman, etc.
