Another review for a movie I didn't watch until the end. Totally unacceptable, but someone has to step up and give some feedback to help out fellow viewers, right?
It's a slice of (low) life in post-war Japan. The traditionally rigid country was apparently loosening up its morals a bit. Girls go out with boys out of curiosity about sex. Older men pick up young women, offering rides with something else on their minds. It's in this world that we find our two protagonists, a high school girl and a small-time con man/pimp. Girl is rescued by boy from rape, boy rapes girl, girl becomes obsessed with boy. Boy then uses girl and enlists her help for his schemes. That's about it for me and I couldn't follow their story much longer as I had sympathy for, or interest in, neither of them or their acquaintances. I just 'knew' that it was going to end badly, but didn't care.
The premise of the aggressive male forcing himself on the female then turning psychologically abusive, while the rather innocent female submits then falls hard for him, is something I've seen in quite a few Japanese movies (or even modern Korean dramas). In a way that's the dynamic at the core of Oshima's later film In the Realm of the Senses. Rather difficult to swallow for today's western audiences. The characters would have to be much more finely drawn or twisted and interesting for me to overcome the gag reflex and keep watching.
