Saw The Enigma of Kaspar Hauser, a film by Werner Herzog about a feral man who appears in a village one day with no sign of where he came from or who had been taking care of him. As a film about a feral person, it cannot help but also be about people living on the fringes of society. Kaspar cannot navigate this world, needs people, but also lacks people. He must rely on the largesse of the state and on charity. It is kind of comforting to see that even with so many disadvantages (or perhaps due to them) he is still able to find some kind of place in this world.
The appeal of the story to Herzog, I think, comes from the fact that Kaspar does not seem to really want to be saved. He spent the beginning of his life in a cellar and, after being freed, expressed a longing to return to the cellar. He says that he is most happy in bed, and his various forays into the wider public are always hassle-filled, humiliating trials. Perhaps he has too much isolation within him already, perhaps this society is not suitable for him anymore.
The film follows Kaspar very closely. We are not really told what's happening to him, we just see that now he seems to be living in this place, now that place. The film moves along nicely and has some fairly funny scenes where policemen and doctors officially react to Kaspar. It didn't fully grab me, but that's probably my fault. I dunno.
