Query: Very disappointing

As a huge Harry Potter fan, and having really enjoyed the first two movies, I was very eager to see 'The Prisoner of Azkaban', and now I wish I had rented it and saved my money. There is almost no character development, and Hogwarts now looks as if it is a ruin. But perhaps worst of all it is a poorly constructed movie. My husband, who has not read the books, but thoroughly enjoyed the first two movies, was completely lost in this one. Scenes change quickly, frequently with no explanation, and while this is not a serious problem if you have read the book, for others it makes for a choppy, disjointed mess. Let's hope that if they make the fourth movie, they'll change directors.
