If you are a die hard fan that gets annoyed when a HP movie diverges from the book, then you might leave this movie frustrated. There are several scenes in the movie that didn't even occur in the book, and there are many scenes in the book that are not in the movie and some where the details are changed. That being said, the movie still flows great and is very entertaining. The process of turning words into movie is not an easy one, so you have to expect some degree artistic interpretation. The movie still gets 4 stars in my eyes and I would highly recommend it.
