Ain't It Cool News has another review of Harry Potter and the Prisoner of Azkaban which seems to be of the final cut. The review is short & does not give away as much material as the other reviews have, but it does contain spoilers. Please be aware of the profanity content on this site.
From the review:
As for Cuaron, he makes the film. This film is an outright thriller. The movie starts out light but slowly the creepiness factor begins to, uh, creep in. And for the first time, we actually sense that we are in a magical world. He keeps his close-ups to a minimum and lets us just feast on the wonderful eye candy. It's all so freaking beautiful!
And terrifying. This is a kids movie? I mean, the stars are kids, but it's all pretty unsettling, especially these Dementors. They seem to be like Kryptonite to our young wizard Harry. It's kind of freaky to see these things roaming around what's supposed to be a school. Also, there's the required Quidditch match, which takes place in rain and is interrupted by the friendly dementors.
