When I saw the trailer I got goose bumps and thought this would be my favorite HP movie so far. As a film it was excellent but as a book fan I was irritated. There was a big scene that was not in the book, that I found did not explain the situation to non book readers but found more confusing to the over all story. There was a big scene in the book that did not make the movie. In the end, once I got over it. The acting was superb. Harry and Ron really made you believe they were on potion. A disappearance was done well. A death scene was cheesy. But overall I will love it.
