“All Good Things,” starring Ryan Gosling and Kirsten Dunst, is “inspired by” the notorious story of Robert Durst, the wealthy Manhattan real estate scion who was suspected of, but never tried for, murdering his wife, Kathie, who disappeared without a trace in 1982. Two subsequent murders were similarly linked to Durst, who remains free today.
Director Andrew Jarecki, who made his name with the documentary “Capturing the Friedmans,” is less successful at limning family dysfunctionality in the fictional mode. Gosling, as the Durst-like David Marks, is scarily effective before his performance turns opaque and horror-movie-ish. Dunst, as Katie, is quite effective at portraying the wife’s descent into a darkness not of her own making. Grade: C (Rated R for drug use, violence, language, and some sexuality.)
