I took my 14 year old daughter to see this although I have also read the books. We did enjoy it more than Twilight - better special effects - a little humor here and there. We did miss the close-ups of Edward and Bella that were in Twilight. We would definitely go see the movie again.
Saw Twilight yesterday with my 13 year old daughter who insisted I read the series too. It was well done, love the closeups of Edward and Bella. I agree with another reviewer who said that if you have not read the book, there are things in the movie that you will not get. Can't wait for the next one to come out!!
