In many ways Kuroneko is a very similar effort to Shindo's Onibaba, a more famous film. Kuroneko leans more directly towards the otherworldly though, and it benefits it to a great degree. The story is very much straight-forward, but what really makes this a strong film and well worth checking out is the haunting atmosphere and cinematography which really makes this a unique film. The special effects, although dated, adds a certain uncanny feeling to the film which, had modern techniques been used, wouldn't have been there.
Two women farmers are murdered and raped by some rogue samurai, but they return in spirit to haunt the local area. The husband and son of those two women returns a hero from the war, and is given the task of destroying whatever has been murdering samurai lately.
Much of the sensuality and dangerous passion returns here, just like in Onibaba, but in this it is even more direct and has an even greater danger. Regardless, if you enjoy the work of Shindo, Onibaba in particular, then this is an essential film to own.
