I am overly critical of movies based on books, but I thought New Moon was much better than Twilight and better than I thought it would be: when I left Twilight last year, I was whining for hours about this that and the other; they changed too much from the book. For New Moon, I didn't have too much ammo for that. The wolves were almost exactly how I imagined them: big and bad@ss.
My problem is that Jake (+ all of the cast at some point, really) sounded like he should've been in a bad soap opera, and the plot got boring near the end.
All in all, though - not a terrible movie, by itself. Certainly not a favorite, or the best I've seen, but definitely better than the first. I wouldn’t recommend it because it’s too easy to mock.
