The Enigma of Kaspar Hauser (1974)****
Werner Herzog makes serious films, there is no doubt about that, and that deserves respect and admiration. However, his style of direction is so minimal, so matter-of-fact, it tends to minimize the impact of the what is taking place on the screen. You can read the script and be very moved by the story but you watch the film and it lays there flat. Restraint is one thing, but overwhelming lifelessness is quite another.
UPDATE 11/09/15: Second viewing experience is much improved. The casting is superb, the images quite impressive and once you know the story and the "enigma", the nuances and subtleties in the film come to life and are quite moving.
