Batman has potential that almost every other super hero movie doesn't because he doesn't have any super powers. He's vulnerable. That allows character development beyond the crap that most of these super hero movies provide. Most of these super hero movies suck because they all rely on a trick, super powers to remove them from any real vulnerability. They all follow a formula that's virtually identical to each other. The problem isn't who plays Batman, it's the story and writing that matters, followed by the direction. There has to be a story line people care about. There has to be characters that people care about. Who plays him only matters if he isn't a functioning actor that can follow a script and story line. He will be whatever the story and direction says he will be. Batman Begins created a story line full of characters that overcame human struggles. It had writing, direction and acting. It was a good movie. Bale is a good actor but it was the vehicle that made the movie. At the end of the day whoever plays Batman is restrained by the writing and the hollywood formula. It doesn't matter who plays him. He's going to be wearing a tuxedo when he isn't wearing a mask.
