Like its predecessor, Harry Potter and the Prisoner of Azkaban marked a potentially perilous place for the film franchise. Chris Columbus chose not to return as director. Richard Harris, who had played a perfect Dumbledore, died before filming began. A new director, a new cast, and a new visual style could have sunk the franchise.
Luckily, the third film of the series made very few missteps. While the style was definitely different from its predecessors, audiences largely enjoyed the changes. This not only turned Prisoner of Azkaban into a success, but laid the groundwork to allow new directors to make each future installment their own.
Yes, the Harry Potter movies seemed to turn every potential problem into a resounding victory. And that’s good – otherwise these nitpicks would seem mean-spirited rather than an opportunity to poke fun at a pretty solid film.
