I just got back from it a couple of hours ago. It's really amazing. It was tough at first since I know the books so well, and had a hard time trying to not consiously compare the movie against it (with the changes made to it). However, as the movie progresses the emotional weight kicks in until the end where I was finally completely emotionally invested in it(and now got a weight another year).
I just wish it could have been longer to allow for some more of the quieter leisurly moments in the book.
I'm going back for a few more viewings, now I know what to expect, I can watch it without replaying the books in my head.
BTW, some guy a few rows ahead of me had a either a digital camera or digital video camara. Luckly he got busted just before the movie started. The usher threatened to call the police on him.
What's interesting was the demographics of the audience. It appeared to be nearly all 25-40 year old techie-type males. Basically a whole audience of my clones
