The acting is amazing! The pain that Kristen Stewart portrays in the movie is even more heartwrenching then the book was, and Taylor Lautner FULLY proved that he is a serious and amazing actor, and not just a boy with hot abs! Now don't get me wrong, Taylor Lautner is quite possibly the most gorgeous guy I have ever seen, so all of the shirtless scenes were beyond BLISSFUL!!!! The one thing that makes me mad and completely ruines a movie for me, is when they don't stick to the book! Don't change things! I feel that Melissa Rosenberg (the screenwriter) did a pretty good job with sticking to the book. There were a few changes, but nothing major so I didn't mind that much. Go see it!
