The Plot: In order to survive, two Japanese women kill and thieve from any soldiers who make passage past their home, but when the younger of the two women enters into a sexual relationship with a drifter, the older woman's jealousy has dangerous implications. Why It's Disturbing: If not as strictly a horror movie as most of the movies here, Onibaba is still a terrifically unsettling film for two major reasons: the psychological intensity of the scenario is extremely high and the terrific cinematography helps create an eerie mood throughout. Yes, it's basically a commentary on how war can warp the minds of even those not directly involved in it, and though not especially graphic, its grim, fairytale-like quality has allowed it to endure over five decades. The final 10 minutes in particular have a haunting quality that'll stick with you for weeks: just try to get the image of that terrifying mask out of your mind.
