Well, I just got back from it and have to say that it was awesome! Not sure what else I can say that hasn't already been said in this thread... Ledger was amazing, I was surprised with how good Eckhart was, and although it was long, it felt more epic than drawn out for me, which is a good thing. The plot was complex at times, but I enjoy films that engage me and reward my attention.

It was definitely dark and intense, but not as bad as I was thinking, based on some of the other reviews I had previously read. Children of Men, now
that[/b] was bordering on depressing near the end! Although still an amazing movie of course... 
Anyway, I thoroughly enjoyed it from start to finish - a great ride. Good writing, acting, plot development and action. Another well thought-out work from the Nolans. I'll definitely be seeing it again.
