I thought the movie was great, it had me literally on the edge of my seat.

Heath Ledger was tremendous. Absolutely captivating. He was almost too good? There were moments here and there when I was sucked out of the movie because I was just watching the Joker and was suddenly struck with the knowledge that this was masterful acting being played out on the screen. I watched the flick of his tongue and the change in his gait and wondered how many hours in front of the mirror it took for Ledger to get to a place where he wholly embodied the character. He was so so good that I was thinking these things while watching the film, when I should have been concentrating on the story and the characters themselves.

In any case, I thought he was brilliant. The Joker brought so many shocking, horrifying, and creepily funny moments throughout the film. Pretty much blew my mind. The movie was long and I felt it. Maybe could have been tightened up a tiny bit, although I wouldn't want to give up a single second of Joker's time on the screen.

I also thought Eckhart did a great job as Harvey Dent, and in fact, Dent was a more interesting character to me than Batman was in this movie.

My only real gripe was Batman's voice. What the hell was up with that? Good thing it wasn't used that often.

Mucho thumbs up from me.

Edit: I want to add that I pretty much squealed with glee when (SPOILER)Cillian Murphy showed up as the Scarecrow for a little cameo. I love that guy, with his strangely handsome creepiness.
