I happen to love the movie. The actors are less strained than the first one. Those that didn't read the books don't seem to understand that the reason Pattinson/Edward looks pained when he kisses Bella is because it still pains him to be so near the smell of her blood. And also because he knows that if he gets too carried away he can kill her. So yes, he looks pained because HE IS IN PAIN!! Can't wait for Eclipse!!!
I read all 4 books and loved them. I saw the movie twice and loved it. I would've loved to see certain scenes from the book come to life but I know they had to squeeze 500 pages into 2 hrs...
