This horror film links human contacts to what doors, literally and figuratively, are open to people. Voices can be electronically altered and the feature relies on psychological suspense rather than graphic violence. A woman is stalked by a disgruntled door-to-door salesman after she slams a door on his hand. There are passages where director Banmei Takahashi relies on some of the more effective moments of Stanley Kubrick's The Shining for inspiration. ~ Dan Pavlides, Rovi
