Excellent documentary.
I'm a docu-holic and a Salinger fan. This film was quality. The sequence of interviews, the unfolding story of who Salinger was, the use of music ... all superbly done.
Despite the author's serious flaws: living out relationship fantasy over and over, never really seeing his wives and girlfriends as more than young muses; losing interest (and even turning vicious) when they reached full adulthood -- Salinger was an intriguing man.
There is a lot to discover and think about through this documentary. I'm surprised at the low rating and very low Rotten Tomatoes score. Maybe, though, that's typical of the mainstream opinion that Salinger himself strove to subvert. Ultimately he is a rather dark figure, but one who influenced the public immensely during his published years.
