L'énigme de Kaspar Hauser

It's a well known philosophical conundrum, would a man be able to think (or even be properly considered a man) if he was denied all sensory stimulation? In Nuremburg in 1828, there was a practical test of this proposition, when a person was discovered in town who had spent all his previous life incarcerated and denied human contact. He was duly taught how to think; but in fact, was not grateful for the experience. Werner Herzog's film examines the strange life of Kaspar Hauser - I find it hard to say whether or not I consider it a good film, because that life itself was so strange. Certainly it better recreated the bafflement of those who interacted with Kaspar than it managed to suggest what it really felt like to be Kaspar - but then, who could know? It's probably not Herzog's greatest achievement - but it's certainly an intriguing subject.
