If you are going to this movie with the expectations that it will follow the book, you will be very disappointed. They change details and leave out two very important things that would have made the movie much more powerful. It seems that they focused way too much on the teen romance and ignored most of the history and details of the connection between Potter, Dumbledore, Snape & Tom Riddle. As far as a Harry Potter movie goes... I still think it was a GREAT film. I would highly recommend that you go see it... but don't expect to get much satisfaction out of staying true to the original novel.
