After watching Twilight I was expecting great things of this movie and could not wait to see it but I was so disappointed.
I personally loved Twilight, it was very true to the book and I thought it was a excellent film that left you wanting more.
New Moon was just nothing special and unlike Twilight I did not want to watch it over and over again.....I almost never wanted to see it again. It starts off great, very true to the book and I could see potential but it is very slow and I found myself losing interest after about 20 minutes. Also if you like Edward you will be very disappointed as he is not in much of the film. This film was needed because you had to see the friendship and love develop between Bella and Jacob but I thought they could have made it better. The soundtrack is nowhere near as good as Twilight and the CGI werewolves are awful.
I personally did not like the choice of Director, they should of chosen someone with a bit more experience. They should of kept Catherine Hardwicke, she did a fantastic job!
The Twilight Saga is basically a Fairytale love story, I didn't feel New Moon delivered much of the spark and excitement Twilight did.
If you love the books, you should and will probably watch it anyway, it's very true to the book but like I said, New Moon isn't the best book of the series.
Also if you loved Twilight, don't get your hopes up for this as it is nowhere near as good.
It's a important and crucial part of the saga as it needs to show how the characters develop and form bonds but I just think it could of been made better.
I myself am looking forward to Eclipse the most as it's a fantastic book and David Slade is a fantastic director - if you've seen 30 days of night you will know what I mean.
Overall - watch it if you love the books and just want to see how it was done but don't expect big things.
