I haven't had a chance to see the movie again since the night it opened in the theatre, but I thought it was pretty good considering the size and intensity of the book. The books are WAAAAY better though, you gotta read them if you haven't. I couldn't put them down.
And the lack of physical intimacy is kind of one of the points of the story. When you read the books you really know what is going on inside their heads, and every time Edward gets near her he just wants to bite her, which will kill her, so as much as he loves her, he can't be that close to her. It is way more involved than that, but that is kind of it, I don't want to give too much away. Your local library should have them, probably a waiting list, but they are worth the wait if you don't have the funds or interest to purchase them.
