Prisoner of Azkaban was my favorite of all Harry Potter movies. I just start the novel marathon from the first one few days ago, have just read the fifth and sixth novel long ago, and this third novel was no disappointment compared to the very good movie version. In fact I am really amazed, having just read the first three books, with the movies-version creators from book one to three because they created a very good movie to catch up with novels written as good as these.
