It's not meant to be a cheering type of movie, nor is it a comedy. It's called The Dark Knight for a reason - it's a dark fucking movie. It was obvious with Begins that Nolan was treating Batman how he should be treated - as a very dark, troubled character fighting a never-ending battle against the darkest villains imaginable in the darkest city there is. As a long time Bats fan, I think it's great that he took the shit seriously and is making darker and darker films. And if you want all action - go see a fucking Michael Bay movie and leave the other stuff for the adults.
