Onibaba (1964) Japanese

This artsy, black and white film has a slow build and a straightforward plot. Two peasant women, mother and daughter, are forced to kill samurai returning from war. By selling their belongings, they can purchase grain. They live in a hut in a huge grassy field. The daughter develops a relationship with a man nearby. The jealous mother tries to subvert this relationship by telling the daughter that sex without marriage is sinful and she will go to hell. When the mother kills a peculiar samurai wearing a mask, her karma ripens swiftly.

The lighting in the latter half of the film is extraordinary and the ending is worth the wait.
