Children, do you know what your parents are watching? School's (still) out for summer, and curator Kathy Geritz has done her part to provide some viewing material with "Screenagers: Documents from the Teenage Years," an ongoing Tuesday night series at Pacific Film Archive. Focusing on works that strive for realism, rather than mainstream pap, Geritz has already shown a pair of movies titled "Thirteen" (I prefer David Williams's quiet Southern story to Catherine Hardwicke's hyped-up SoCal one), and next week brings "Seventeen" -- Jeff Kreines's and Jole DeMott's legendary and obscure 1982 documentary set in Muncie, Indiana, which was suppressed from PBS by outraged corporate sponsor Xerox. Johnny Ray Huston reports in SF360.
