This simple movie of a young, poor couple trying to enjoy their day off with little money is the best non-Italian neorealist film I've come across. True to the neorealist spirit, not a lot goes on; a gloomy Gus and his girlfriend wander the city, she trying to bring him out of his depression while it seems all of life is determined to keep him in it.
The movie does a good job of painting a picture of Japanese post-war poverty. Chieko Nakakita gives a wonderful, charming performance as she tries to cheer her beau and to fight against her own distress at their plight. Some scenes are truly striking, notably a trip through an uptown club and a tense, almost wordless scene between the two lovers.
The final big scene in the film drifts away from neorealism. It's an odd scene, and from a critical point of view I'm not sure what to make of it, but viscerally I found it rather affecting. I would love to know how audiences responded in Japan at the time.
There are a few issues in the movie. Some scenes go on too long (like the aforementioned "final big scene." And the guy's sudden emotional upswings often seemed to come out of nowhere, unlike his depressions, whose genesis was always clear. But overall it's a very human, simple movie with moments of joy and moments of pain, and I highly recommend it.
