Query: Annoying and utterly uninformative

This has to be one of the most grating and pointless documentaries I have ever seen. The filmmaker is utterly self-absorbed and neurotic. He obviously believes his incessant thinking to be a marker of a superior intellect, when he is actually a rather typical worrier who never learned to quiet his mind. He overuses repetitive sounds to mark the passing of time (yes, ticking of the clock, we get it) and stock footage from the 1940's and 1950's (amusing a few times, but more than half the film is lame clips). In the end, I felt annoyed at his obvious desire for an instant cure (hence his sleeping pill addiction), his more-creative-genius-than-thou pride in his insomnia "problem," and hokey editing style.
