Kiyoshi Kurosawa, once again, is able to craft a suspenseful, slow-paced, and psychological story using his explorative direction choices on the exercise of horror, dread, and terror.
For 45 minutes, it's atmosphere and it's subtle uses of horror and tension is mundane, yet, purposeful in the good ways to crawl right into your skin. What Kurosawa is great with his horror works is that he doesn't use much gore and rather uses the terrifying atmosphere and concept to craft the dreariness and creepiness within his narratives, and this short succeeds with it. Provided with solid performances and a good pacing.
If you like Kurosawa, I recommend it.
