As I should have expected from director Nagisa Ôshima, "Hakuchû no tôrima" ("Violence at Noon") is a thoroughly unpleasant film. It's central themes are rape, murder and suicide....so you might want to think twice before you watch it.
Eisuke is a horrible person...pretty much human garbage. Despite having no discernable good qualities, two women love him. Why this is the case becomes SOMEWHAT apparent through the course of the film, but they refuse to go to the police after there's a string of rapes and murders...even though they both know that Eisuke is responsible. With one woman, instead of telling the police, she sends letters to Eisuke's wife...trying to get her to turn in this despicable man.
There's more to the story than this, but suffice to say I disliked everyone in the film....which is NOT unusual for this director. He tended to often make films about amoral people and they are certainly NOT everyone's taste. I frankly have never loved any of his dark and unpleasant films...and this one, though well made, is just unpleasant.
