I'm still looking forward to this movie. The Batman Begins reboot was the best thing that ever happened to the film series, and The Dark Knight looks to continue the awesomeness that began in the first one.
It is a shame that Heath Ledger died recently, and I'm sure that his final role, as the Joker, will be his best. This Joker seems better than any other interpretation of the character, and is probably closer to how the Joker was meant to be.
On the other hand, it's also going to be really sad knowing that Heath died. I can't imagine him playing the role anything less than perfect from what I've seen.
