The much-anticipated sequel to Japan's most globally infamous export won't convince Battle Royale fanatics; whereas the original functioned as scathing, modern satire, this follow-up implodes ostensibly into complete self-parody. And it is hysterical. Laughter came nervously in the original, as if to alleviate the perverse tension of an adolescent cat fight with firearms, yet this sequel piles on ten times the blood, body count and melodramatic death scenes to glorious, ridiculous effect.
