What makes “Terri” special, though, is that you don’t feel pushed around by the narrative. Mr. Jacobs paces his scenes with a relaxed, almost dreamy rhythm and allows odd, interesting details to catch his ear and eye. A pushier, less confident filmmaker would have underlined the quirkiness of the characters, condescending to them with mockery, sentimentality or a coy blend of the two. But everyone in “Terri” is allowed to be opaque and unpredictable, the way real people are.
