Reality, generally considered over-rated by the moving-going public, is the unapologetic core of SF DocFest (Sept. 28-Oct. 10). But from its inception in 2001, SF Indie's (almost) annual documentary showcase (they skipped 2003) has eschewed the dry, serious, good-for-you associations which supposedly plague the genre, emphasizing the idiosyncratic, odd, outre, subcultural, even the sub-subcultural (cf. this year's attention-hound, "Wiener Takes All"); all the while slipping in some solid social and political fare when, so to speak, nobody's watching.
