I think it's a little simplistic to explain a work through the psychology of its author. In other words, that Haneke has emotional problems, so I don't have to take his films seriously. By using this argument, the viewer retreats from the challenges of the film.
There is, however, a change going on in the world. There's far more interest in drawing now than there has been in a long, long time. Schools are beginning to teach drawing again in a serious and meaningful way.
