I finally saw the movie yesterday, too. In the middle of the film, it just stopped and it started playing previews for about 15 minutes. Then it started in the wrong part. My cousin went over and asked about that and they gave us 5 free tickets to come see it again!

Your right, it definitley wasn't for little kids. My 7 year old sister came. She's reading the 5th book right now, and my mom let her come to the movie. She wasn't scared at all. She said it was because she knew what was coming from reading the book.
