Funnier than I would have thought possible

Rating: 10/10 (3 July 1999)

This is it--South Park as Disney mini-epic. Dozens of songs ranging from hysterical giggle-fests ("Uncle F**ka", "What Would Brian Boitano Do?") to the actually touching ("Up There") highlight the most ambitious South Park storyline yet: The invasion of Canada and the triumph of Satan.
Witty, thoughtful, emotionally rich (yes! really!), and wonderfully self-referential, and with some of the most *un*gratitous vulgarity in film history, this is one of the finest movie fantasies ever made. Only the absence of Mr. Hankey keeps this from being the best South Park ever.
