I have to say that I was pleasently suprised at the movie. My only complaint about canon is that because Rob's Edward is slightly more animated than the book's, it's not as obvious they are *so* in love in the movie as it is in the books. Another five minutes of them building their relationship in the beginning could have solved that.
The horribly low budget hurt, too. The actors were AMAZING.
I could go on but I'll leave it at this... I actually had more critiques for the movie than my friend who came with me who's never read the book. She had no complaints what so ever.
It's a good movie. And the next two DEMAND a higher budget!
