The Plot: A detective investigates a bizarre series of sudden suicides across Japan which appear to be linked to a popular musical group. Why It's Disturbing: You needn't look any further than the movie's opening scene, in which 54 schoolgirls hold hands and jump onto a train track, being simultaneously splattered across the station by the oncoming train. If the rest of the movie never quite reaches that same level of screwed up, the other suicide sequences throughout are still thoroughly unpleasant, particularly when a young girl puts her head into an oven while her mother casually slices off her own fingers, smiling as she does so. It would've been easy for Sion Sono's satirical tone about the state of contemporary Japan to undermine the movie's genuinely horrifying content, but considering the rampant suicide problem in the country, it's disturbing for more reasons than merely its voluminous gore.
