1. You have been raised to feel that self-introspection is nothing short of vanity and it is wrong. The fact that Alan Berliner has made a film that is about HIS sleep problems (not the field of sleep problems in general) are evidence (to you) of his self-indulgence and narcissism. (those who commented that they would have like to learn more about sleep problems in general - go take a course).
2. You are an anti-Semite. Interesting how so many of the critical comments here drop clever little Yiddish-isms ("kvetching," "shlub," etc.). Alan Berliner is a New York Jew - deal with it. If you don't like his accent or his hairy back don't watch the film.
(Full Disclosure: I didn't sleep well last night for some reason and I am irritable. Well actually I know why I didn't sleep well -- I was up late watching "Wide Awake." HA!)
