Fear of technology is powerfully explored in this sadly overlooked Japanese horror from director Kiyoshi Kurosawa (Tokyo Sonata). It centres on a group of university students who set out to investigate a series of baffling suicides that seem to be linked to web cam shows that promise visitors the chance to communicate with the dead. The film works so well because its never in your face with its scares, instead worming its way under your skin like a virus with an atmosphere that feels at once alien and scarily real. It can be looked at as social commentary on the increasing isolation of Japanese society led by the dominance of technology. But also enjoyed purely as a ghostly horror with some of the best sequences the century has to offer, not least the scene in which a mysterious woman walks/dances in slow-motion down a dark hallway.
