If you have not read these books, there is a solid chance you really won't understand the motivations of the characters. Pattinson plays Edward just like Meyers' alternate book from Edwards point of view so be ready to see an Edward not like the one we read in the Twilight book. Its really hard to get super deep characters without hearing or reading what they are thinking. I think Pattinson and Stewart do a noble job of it and the movie has some really great moments. Overall I give it a B because its really disjointed and lacks flow. However, I also give it a B because I happen to love the Twilight series!
