I came across this movie because I'm a huge fan of Kanata Hongo's frequent portrayal of grotesque and borderline crazy characters...and psychological horror films are a huge guilty pleasure of mine. The story is pretty self-explanatory, but some things don't get developed or explained as well as they should've, especially the reoccurring twists & turns, resulting in what might seem like an unclear ending or reasoning to some viewers. Casting, like I said earlier, I'm fueled with theatrical respect when it comes to Kanata Hongo (or anyone, really) acting his usual 'insane' roles, but he wasn't the only one that impressed me throughout the movie. All actors/actresses were so great at portraying their...unique characters, I almost felt that the game they were playing was real despite all the unique features and attributes attached to them. Overall, I'd recommend this to anyone who isn't easily triggered by various taboos. They're all over the film, literally; it can toy with the mind and it is slightly gross to see how far people are willing to go for the mere addiction of control. But in being so, it is an interesting film. Watch it with an open mind, and everything will run smoothly.
