Saw this movie w/ 35-40 year olds. It was better than any of the other Twilight movies. Followed the books really well, even had some quotes right from the book, I was very impressed. The action was awesome, and Edward and Jacob had some great moments, and even Kristen's acting is coming along, not too many studders or eye squinting. She's come a long way. Would surely see this movie over and over again!
If you love the books, you will love this movie. New Moon stayed true to the book, unlike the first one. Very minor details were left out. The wolves and the Volturi were all great. I highly recommend seeing this movie, even more than once!
