Take a social-realist feminist trope – downtrodden wife – and have her become obsessed with sex. Yes, it’s a Sion Sono film as only he can make them. Given the subject matter, even the title is provocative. Expect gratuitous nudity, outrageous sex scenes, gruesome exploitation… Don’t watch this one with your granny. Take the opening scenes. A woman’s body is found (yes, it’s also a Kafkaesque murder mystery), but the head and legs belong to a mannequin. Cut from a much longer film to a mere 144 minutes for the international market, this won’t be for all tastes. Some may find it depraved. It’s not always easy to watch and contains too many repetitive sex scenes, which slows the pacing. Not one of Sono’s best, but his films are never less than startling, which you can’t say of many films these days.
