4th viewing, no change in response. The obsessiveness on display can be a metaphor for any kind of fixation, though to my over-exposed eyes it can be a cautionary tale about cinemania ("Was he into movies? Was he a movie buff?" "I can tell you that he was not into people.") Only new thing I noticed was a textbook, film-school-approved graphic match between a diagonal line of text and the Golden Gate Bridge: words inscribe the landscape — with terror! Just a perfectly made film, richer than it knows, delivering information and melancholy with equal measure.
