Theatrical remake of a well-regarded 1968 "CBS Playhouse" special for television about the secret drug-life of today's suburban teenagers was directed both times by David Greene, who practically disowned this franker, R-rated version. The problem could be in the central casting: Eli Wallach pushes far too hard as the clueless father of a tripping 16-year-old girl while mom Julie Harris smokes and looks distraught (when her daughter tells her she's on the Pill, Harris hilariously responds, "I think I'm losing my mind!"). The original rock songs (performed by The Bead Game and The Glass Bottle) are dreadfully pedagogic--hoping to 'inform' us with their lyrics--but, since nobody can reach this alienated girl, what good is it probing her inner-thoughts to music? Generation Gap tale has a solid cast (including Hal Holbrook, Cloris Leachman, Rue McClanahan, Stephen McHattie, Don Scardino, newcomer Deborah Winters, and Rutanya Alda as a pixilated nurse), yet the pitch of the film is off, hysterical instead of riveting. ** from ****
