Grotesque (2009 film)

Grotesque , Gurotesuku? is a 2009 Japanese splatter horror and exploitation film written and directed by Kji Shiraishi.

As the torture progresses, it is revealed he is simply doing it for sexual stimulation, and tells the couple he wants the two to survive. He finally castrates Kazuo, claiming he has found all the sexual relief he needs, so no longer needs the couples services. The couple is moved to a room which resembles a modern and clean hospital room, where the kidnapper takes care of the couples wounds. It gradually becomes apparent that the man has professional medical training, refined manners, taste for classical music and good wines and dresses in expensive clothes when he is not in surgeon dress. He even mentions he is a wealthy man, which suggests he may be a reputable surgeon, not merely a violent sadist, looking for an extreme way to obtain satisfaction in his lonely life. The couple also notes the doctor has a particular rotting smell always present behind his clean and elegant appearance.After several days healing, the doctor simply tells the couple they will be free to go, he will turn himself to authorities and, as apology for all the suffering he inflicted to the couple, he will give them all his fortune which seems to be very large, as compensation. After all the horror, in a moment alone in the hospital room, Aki and Kazuo promise to support each other once they leave and become a couple. It is unclear if the madman is playing with the couples hopes to survive immediately after telling them they will be released, the couple is taken back to the basement. After being drugged, they are shackled again, exactly as they were the first time. ........
