The Dark Knight

Excellent movie. Best of the trilogy. Lovely music. Nolan is a genius. So is Heath Ledger.

This has no competition. It is the very finest comic-book character movie ever made. Knowing the Burton, Donner and Nolan filmic adaptations of Batman and Superman exist helps me to sleep at night. They are Exhibit A of 'How to Make a Comic-Book Movie'. Nothing else has ever come even remotely close. These seven films (I include 'Superman II' because it was mostly Donner's work)--and Nolan's trilogy especially--are what I imagine a great director like Kubrick, Hitchcock or Kurosawa would have come up with, if they had ever been asked to make a Superman or Batman movie. They are the easiest for an audience to identify with because in these the scripts most approximate human emotions and the typical conundrums of the human experience--in short, are the closest, in a good way, they come to the complexities of the human condition. Peerless.

Perhaps the best Batman movie of all times. I think that this Batman trilogy presents the well-known superhero history in an unexpected way with the capable to maintain on the edge of the chair all time.
Heath Ledger present an excellent impersonification of a psychopath.
All support roles are magnificent.
And Bruce Wayne role played by Christian Bale, shows a human being behind of the mask.
