I saw this film last week. I've read all of the Twilight Saga so was looking forward to the film of New Moon. On the whole, it was fairly good but I do agree with other reviewers, Twilight was better. I enjoyed it but found a few flaws with the film.
In this film, Edward seemed to play a much smaller role, I don't think his scenes were given enough weight and it often seemed that his actions were explained very well. Also a couple of scenes seemed truncated - perhaps they'll be in the deleted scenes section of the dvd? I hope so.
For example, when Edward tells Bella that he is leaving. Far too quick. When it shows Edward taking a photograph from Bella's bedroom, it doesn't show that he is taking all evidence of his ever existing from her - a key reason why she is so miserable afterwards. And the scene when the humans are being taken as food to the Volturi - Bella seems hardly bothered unlike the book where Edward has to force her to move on. And when Edward returns - they resume their relationship without much explanation of why he has changed his mind. No mention that he was going to come back to her anyway because he couldn't stay away.
I do think the scriptwriters must take some of the blame but presumably they were directed where to focus the film?
I did think the relationship with Bella and Jake was very well portrayed and I don't agree that the actor playing him looked too young. However, I felt that the relationship between Bella and Edward seemed to play second fiddle to this.
