Batman was heavily inspired by creepy, shadowy 1930's horror movies, such as The Bat Whispers and The Man Who Laughs, as well as film noir. As such, it makes sense that Batman works onscreen better than any other superhero. The hugely appealing visual of a man dressed as a bat, and the relatively easy-to-suspend disbelief compared to superheroes with powers, make him perfect for cinema. Christopher Reeve or Tobey Maguire only put on costumes and pretend to do what their characters do; Keaton or Bale put on the costume, drive a real Batmobile, learn real martial arts, get real toys.

I'm not suggesting the Batman movies are modelled solely on the Bond ones, they are not. However, the James Bond movies have been an huge influence on every action movie (just ask Christopher Nolan which films inspired him on Batman Begins).
