"Kuroi kawa" ("Black River") is a most unusual Japanese film. While most films from this era tell stories about love or samurai warriors from the past, this one is planted firmly in post-war Japan...and among the lowest classes of society. Instead of showing nice folks, most people in the film are of the dregs...prostitutes, pimps, voyeurs, thugs and the like. And, for the most part, these people are incredibly ugly...not just spiritually but physically as well. It seems that director Masaki Kobayashi wanted to expose this ugliness...and the film is indeed an indictment of this. And, I am pretty sure Japanese audiences must have been shocked to see this!
The story is set in an incredibly seedy rooming house near a US military base. Most of the residents seem like degenerates and yet, oddly, a seemingly nice engineering student decides to live among them in order, he claims, to save money. It's hard to believe anyone living there who has any other options. He is interested in a lady who works as a waitress but before they can develop a relationship, she is kidnapped and raped by a creep they nickname 'Joe the Killer'! Now, she's stuck in a relationship with Joe...as he refuses to let her go, as she is now his 'property'. And, so she is hoping, somehow, the student will be able to rescue her from her plight with this violent brute.
If you are looking for a nice film or one that leaves you happy, then by all means do NOT watch this movie. Now it's not a bad film....but it is a bit depressing and sad to watch. After all, it's about the writer's perceptions about he breakdown of the social fabric in Japan. Interesting, very well crafted...and, at times, hard to watch.
