“Rudderless” opens Friday at Sundance Cinemas. R, 1:45, three stars out of four.
As an actor, William H. Macy has never had much time for sentimentality on screen. In his first film as a director, “Rudderless,” he expresses a similar reticence to get mawkish, even when handling material that has such potential to get maudlin. Instead, “Rudderless” is a well-acted, sensitive, and surprisingly funny at times debut.
