Hmm... it's not that great I'm sorry to say. The voices are very unclear and it's very pretentious considering it's a comic book film.
I wish one day someone would make a Batman film that's got Batman in it for +80% of the time.
To be honest, I suspect that if they did, it'd end up being a bloody awful film! The trilogy that Chris Nolan wanted to make was all about the characters. Batman himself is a cipher. There's an argument to be had that Batman is the person and Bruce Wayne the mask he wears - in fact, Nolan mentions it across the trilogy himself a few times, but all the major characters have different levels to them. And actors capable of pulling that off. Can you imagine an hour of Batman growling and posturing? <shudder>
It's not perfect by any means, but I think it works as a fitting end to Nolan's take on Batman. I still prefer The Dark Knight, though.
