Harry Potter and the Prisoner of Azkaban (2004, dir. Alfonso Cuaron)

Potter is threatened by a notorious escaped prisoner and ally of the Dark Lord. The third in the sequence is a touch darker, expanding the movie universe away from the quest-based adventures of parts 1 and 2. A step up all around, with confident direction, better effects, and actors maturing into their roles.

Wonder Woman (2017, dir. Patty Jenkins)

An Amazon princess journeys to the outside world to defeat the God of War. Superior superhero origin story, benefitting from freshness of its lead character, a generally light touch, and a well-realised World War 1 period setting.
