Sion Sono is a director of extremes — including an extreme dislike of being categorized. Just when you thought you had him pegged as a maker of violent black comedies with classical music scores, such as "Ai no Mukidashi"("Love Exposure"), he turns out heartfelt, albeit still violent, dramas with nuclear disaster themes, such as "Himizu" and "Kibo no Kuni" ("The Land of Hope").
