Harry and his friends return to Hogwarts for their third year. Before they return Harry runs away from the Dursleys, who have always treated him badly. Just in time before he has to spend the night on the streets the ghostly Night Bus picks him up. After a quick spin about London they drop him off at the Leaky Cauldron Inn. On the bus Harry learns about the escape of Sirius Black from Azkaban prison.
Once back at the School it's the usual story of the three lead characters, Harry, Ron and Hermione, getting into trouble and uncovering the mystery of who and where the Prisoner of Azkaban is. There is a bigger role in this movie for all involved, the rivalry between the gang and Sliterines Draco Malfoy grows ever deeper, with a lovely turn by Hermione.
This film in general is much improved over the last two, especially the awful Chamber of Secrets. The dark and moody styling seems to fit this latest Harry potter, although I don't think it would have worked for the previous two movies, this has darker source material, and Harry is getting older and wiser, and possibly more mischievous as the books progress. Although this is an enjoyable film it is still guilty, as with the last two, of being disjointed. Having never read the books I don't know the stories at all, but even I feel that at times bits are missing or being left out, the viewer is being left to sometimes guess how the story progresses from one scene to another, whereas the books explain it.
