‘Time Indefinite’

Documentary maker Ross McElwee’s follow-up to his cult hit “Sherman’s March,” follows his life in the recent past. He attends a family reunion in Charlotte, N.C., is married and endures a series of unforeseen sorrows. What starts out as jaunty and dawdling becomes a kind of meditation on mortality. But McElwee (pictured, with friend Charleen Swansea) doesn’t make you wince at his seriousness. His bafflement at what is going on in his life is a genuine, unadorned response to tragedy. You don’t feel as if he’s exploiting his ill fortune. This is a one-of-a-kind movie because McElwee himself seems one of a kind (KCET Tuesday at 10 p.m.).
