Pleasantly surprised at how it followed the book without any major deviations I can recall. Well worth seeing at midnight, except for the preview for "The Unborn" (looks HIDEOUS.)
I do wonder how it would go for those who haven't read the book - they didn't seem to give as many "dumb" explanations like were done in the first couple of Harry Potter movies for non-readers to catch up to speed.
I almost like the movie better as it's not all presented from inside Bella's mind like the book, where she won't stop talking about how gorgeous Edward is and how ugly she feels... etc. Bella's quite likable in the movie - and Kristen Stewart did a really good job.
