Task: Sentiment Analysis
Input (English): 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.
Output (English): positive
