I though New Moon was fantastic! I went to the midnight showing with a friend and again the next day! As much as I liked Twilight, New Moon was much better.
They stayed true to the book, for the most part, and didn't leave anything too significantly important out of the script. I don't think "book Bella" would have ever b**** slapped a were wolf and wish I could have heard Edward/Rob recite my favorite quote, the whole "my life was like a moonless night" thing, but aside from that I was 100% satisfied.
Jacob/Taylor's new look alone was worth seeing the movie multiple times!
The new element of action was great too.
So Twilight fan or not, I highly recommend this movie!
