Twilight the movie

My sister really wanted to go see the first showing of Twilight this weekend. We convinced her to wait until Friday night and we would go with her. So 7 of us went to the 10pm show Friday night. We had so much fun and I really enjoyed the movie. With all the bad reviews and people saying it wasn't like the book, I went with pretty low expectations. But I really liked it. No, it's not exactly like the book, but what movie made from a book is?
