Most importantly, our own Scott Pepper is most pleased:

On the whole, this is Cuaron's film through and through. By taking a realistic approach to fantastic material and targeting a more adult audience, the director has made the franchise his own. The new approach to Rowling's work is a welcome one after two trifling attempts by Columbus. Though Cuaron will not be around for the fourth film (Mike Newell has that honor), the incredibly dark and depressing Book Five could be right up his alley.

Harry Potter & The Prisoner of Azkaban is both a continuation of the departure. Fans who enjoyed the first two movies will find more to love here, and those who found them childish will welcome the more serious approach.

Two final recommendations: First, if you have not read the book, be sure to either do so ahead of time or go with someone who can explain it to you afterward. Secondly, if there is an IMAX theater showing the large screen version of the film anywhere near you, see it there. You won't regret it.
