There is much praise heaped upon Mizoguchi Kenji's "Sansho the Bailiff," including the box cover calling it "one of the finest films ever made." I probably wouldn't go that far, but it is an excellent movie ranking amongst the best of the genre, standing tall with Kurosawa Akira films such as "Red Beard." It is very heavy, with a strong message.
Like Kurosawa, social responsibility is a strong theme in Mizoguchi's works. In "Sansho the Bailiff," we see a blending of the social classes, as an honest aristocrat is exiled, his wife sold to a brothel and his children made slaves, all because the aristocrat believed peasants deserved happiness as well, and that the aristocratic class had responsibilities to the peasants. Mixed together, you see cruelty and mercy amongst both classes, from the tyrannical Sansho and his friendly son Taro, or the martyred slave Namiji and the cruel Zushio willing to brand another slave on the head with a hot iron.
To this there is the message of mercy. "Be hard on yourself, but merciful to others" is the mantra passed from parent to child. A sacred image of Kannon, the Goddess of Mercy, is a family heirloom, passed down from generations as a reminder.
As in all Mizoguchi's films, it is ultimately the women who suffer, bearing the sins of men on their capable shoulders. Mizoguchi is considered a feminist in Japan, although the standards are different and most Americans would probably not consider "Sansho the Bailiff" a feminist film.
