As an avid Twilight fan, New Moon was my least favorite book, therefor it stand it will probably be my least favorite movie. New Moon was a slow moving book, i feel they did the best with what they had to work with. New Moon is important to the series for informational. My biggest problem is the way Edward "sparkles". In twilight it was a subtle glow, New Moon it was way over the top. It is hard enough to get vampire fans to even watch twilight, this "sparkle" looked like a joke.
All in all, if you like Twilight, you need to watch it before Eclipse comes out, but it is not a rush out and see in the theater kind of movie.
