I've been looking forward to this for about two months, and so I went to see it today at the first showing. I was really stoked for it, even though I was pretty sure that I would be disappointed.
I wasn't. It was worth every penny, I would have paid double even. The whole time I sat there thinking "this is really good, what were all those negative reviews about?"
First off, the music was completely amazing. I first heard Bella's lullaby about a month ago and was mildly disappointed, but that's not to say that it wasn't pretty in its own way. I hadn't heard the rest of the soundtrack, and throughout the movie I was impressed with the editing in, as well as the composing itself - there was a good balance of incidental music as well as songs.
I also have to say that the trailers and clips given beforehand simply don't do the movie justice. Some bits were edited/changed (for the better) and in others the fact that you could properly hear and see it in good quality made it so much better.
I was expecting Kristen to be a little stiff in her acting, but that preconception soon went away - she was the perfect Bella. There was enough clumsiness and awkwardness, and I also liked the fact that she did voice-overs on parts that were inside her head in the book - especially the prologue, and reprise.
I went in thinking Robert Pattinson was hot. I came out with a crush the size of a planet on him. I totally forgive Catherine Hardwicke for over-doing the close-ups. Very effective. At the beginning he played Edward a little differently to how I was expecting - perhaps to do with the script - but again, I wasn't disappointed. He soon merged into the Edward I knew - maybe this is only because I've read Eclipse multiple times and am more used to the more developed character of Edward, rather than the weird who-is-this-gorgeous-guy at the beginning.
The chemistry between the two is amazing, I've never seen anything like it. I found all of their acting really believable, Robert played Edward especially well at both extremes, the incredibly happy, joking Edward with the sunglasses, and the tormented Edward as Bella asks him to change her. I especially liked the line "you're in here because of me" - very Edward and New Moon-esque.
There were some great bits in I was really pleased about from a book-reader's perspective. The looks between Edward and Carlisle, when you knew Carlisle was telling him something was one example, as was some of the smaller things - Alice and Jasper holding hands, James putting his arm around Victoria etc. There were some cool sequences (although two of the friends I went with didn't like them), such as when she figures out he's a vampire, and the whole "let's not play with our food" bit.
I didn't see what the problem was with the directing/editing. The section in the woods made me feel dizzy, but that was all. In the book his sparkling is described as looking like his skin was covered in diamonds, and I thought it looked exactly like that - they couldn't have done any more without it looking fake.
All of the other acting was brilliant. Although I thought the only bad bit was when Bella was leaving, Charlie soon had me in tears, which made up for Kristen's temporary bad acting.
I also really enjoyed the humour in it - there was a really good balance. Not corny, but it made it light-hearted in the right places.
I know I've forgotten a lot, so when I remember it I'll come back to say. I'm still kind of in shock, and I'm going back to see it again as soon as possible.
