This comment contains spoilers. A child lost his parents during a robbery in Gotham City and he grew up full of anger. He can't kill the killer of his parents and he decides to become a vigilante. He travels around the world to know criminals (in China but not in Gotham City) and a mysterious man suggests him (after 7 years!) that "criminals are simple-minded" and "You have to know yourself, not your enemies". And a ninja-warrior training begins. But ninjas want destroy civilization and our hero discovers suddenly that Vengiance is worst then Justice. So Batman begins. This is a very good lesson in ethics. Those lessons are repeated all along the movie, explained in monologues and dialogs by friends and foes even when they're fighting each others. But a good lesson in philosophy is not a good movie: Batman Begins is a really boring movie, without humor, self-celebrating and really too dark to be enjoyed. "It fits the spirit of comic books" is the defense-line drawn by it's defenders. Oh yeah, of course: maybe geeks are celebrating it. But Sam Raimi, at least, had the courage to violate, sometimes, the spirit of the original Spiderman comic books and he made three very funny and enjoyable movies. Christopher Nolan's Batman is just boring.
