New Moon is better than first Twilight movie and did an excellent job staying true to the book while keeping the story and action moving. The screenwriters pulled much of the dialogue straight from the book so fans could hear their favorite lines, but also added some cute references to pop culture. I was surprised at the humor in this movie, much of which seems to be because we are getting more familiar and comfortable with the characters.
The acting was better, as well. While I'm die hard Team Edward, I have to give Taylor Lautner props - he's got some great acting chops.
Even though New Moon was my least favorite of the books, the movie was great.
