Powerful and haunting, this upsetting documentary by Andrew Jarecki examines the scandals enveloping an upper-middle-class Jewish family in suburban Long Island, as the father and a teenage son are accused of sexually abusing countless boys. The story unfolds over many years, with as many carefully delayed revelations as in a well-plotted fiction film, and though Jarecki raises a good many questions about the Friedmans that he doesn’t entirely resolve, his exploration of the larger issuespolice investigations, community hysteria, and the family members’ obsession with filming themselvesis much more revealing. 107 min.
