Suzuki Seijun is a master of craft, and one of the greatest visual stylists ever. This film is a loose reworking of Branded to Kill, the jakuza clasic that marked the end of his career at Nikkatsu studios, whom Suzuki was a contract director. That film took many risks in narrative and presentation, and it was post modern before post modern became chic.
Before you complain about why you don't understand this film, just look at it less in terms of narrative and more in terms of the abstract. It's a spectacle of sight and sound, and one of the most beautifully shot movies in recent times. The photography alone is reason enough to see it.
This is a film that does not bother to explain it's convoluted story because it's very design DOES NOT warrant that path. It's cinematic style brings to mind elements of Kabuki and opera theater. The performances are mannered and exagerated, something that is understandibly strange if you are not japanese.
All in all, it's a film devoid of anything rational and a spectacle of sight and sound. A 10.
