Daniel Radcliffe in Harry Potter & the Prisoner of AzkabanHARRY POTTER & THE PRISONER OF AZKABAN

Anyone interested in the distinction between routine direction and inspired direction - anyone who has ever wondered what, exactly, it is that a director brings to a movie - should compare Chris Columbus' first two Harry Potter films with Harry Potter & The Prisoner of Azkaban, helmed by Alfonso Cuaron; Columbus' films are the work of a by-the-numbers craftsman, and Cuaron's is the work of an artist. (Which isn't to say that everyone will prefer Cuaron's style; many people would rather dine on Big Macs than filet mignon.) Cuaron isn't quite able to overcome the series' built-in limitations - the familiarity of the storytelling arc, the "surprising" character reversals that aren't really much of a surprise, the fact that all three movies are too damned long - but for those viewers, like me, who've never been overly enamored of the Harry Potter film series, Azkaban is as fine an entertainment as you could hope for, a visually audacious work with moments of true magic, and it improves on Chris Columbus' vision tenfold.
