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.
My view is different. Public relations are a key component of any operation in this day of instant communications and rightly inquisitive citizens.
The most important things are the hardest things to say. They are the things you get ashamed of because words diminish your feelings - words shrink things that seem timeless when they are in your head to no more than living size when they are brought out.
