I thought it was better directed and written than the last one. The whole thing moved at tremendous pace, which is what the last one lacked so badly. It was a very difficult book to film and I do not think it could have been done much better.
The script was less lively than the first two films. I think the problem with Michael Gambon, was that the scriptwriter did not really give him anything to do. As a fast moving children's film it was not bad.
