Adults...struggle desperately with fiction, demanding constantly that it conform to the rules of everyday life. Adults foolishly demand to know Superman can possibly fly, or Batman can possibly run a multibillion-dollar business empire during the day and fight crime at night, when the answer is obvious even to the smallest child: because it's not real.
The thing that separates this film from other superhero films is that Batman is entirely plausible. There aren't any superpowers involved in the film. There aren't any mutants, no characters from other planets. It's set firmly in the real world. And I think in that way it makes it more accessible to the audience. You could never be Superman, you could never be The Incredible Hulk, but anybody could become Batman - you'd have to inherit a couple billion dollars and have all these gadgets, but nevertheless it's possible. Like maybe if we tried hard enough, if we worked hard enough, if we trained hard enough, maybe, just maybe, we could become Batman. David Goyer
Bruce decides to spend the family fortune on capes and crime labs and to fritter away his free time fighting crazy criminals. Now that's an out-of-the-box calling. What sort of person makes a life change like that without radical submission? Without that submission, without an understanding that there is something greater out there, the principles of the comic villain look far more reasonable.
