As psycho-killer movies go "Lesson of the Evil" is up there with the best of them. It's by the Japanese horror maestro Takashi Miike and is set for the most part around a school where handsome young teacher Hasami, (Hideaki Ito), has his own somewhat extreme methods of dealing with rule-breakers. Miike's genius is to treat everything so matter- of-factly the film is almost banal to begin with before letting rip. Although extremely violent, this isn't torture porn but a brilliant slow-burner than builds to a fairly devastating and disturbing climax. I certainly can't see this playing in parts of America where school shootings have become almost common place. By making the villain someone who, in another film. should have been the hero Miike neatly subverts the genre, (think "Dexter"). There's also a nice self- depreciating streak of humour running through the picture, not to mention several great recordings of 'Mack the Knife'. Excellent, if very unnerving.
