An inventive, suspenseful exercise in claustrophobia. A Japanese thriller that sets itself a tough challenge by being entirely set in two rooms. Not completely successful, but taut, surprising and well-acted. One might find the film somewhat reminiscent of SAW two men trapped in room and pitting against each other but unlike that film it dares to stay with its premise and keep the hero locked in his cell throughout the film. It's like watching a lab experiment. Some might find the contained suspense tedious, but this reviewer found it enthralling. The sound and imagery of the film are stunningly well realized. This is a certainly a good film to use to show off a good home video system. Just right for a late night movie fest, when one is in the paranoid mood. It certainly kept me awake that night.
