“Robocall” (*** out of four) was an affecting drama about a lonely widower and former Vietnam vet (Gary Sturm who also wrote and directed) who is going through the tedium and realization that he is at the end of his life and doesn’t have much left and is beset by a series of increasingly aggressive robocalls and telemarketers that begin to rattle his nerves and drive him further into madness. Not much in the way of plot per se but Sturm does a very impressive job on both sides of the camera and makes this story alternately moving, intriguing, and funny. Only the ending is a bit abrupt and a bit of a letdown.
