Shirley Knight was a fine actress and she inhabits the role comfortably here, portraying a range of emotions and characteristics smoothly. The rest of the actors are well cast and are very believable. The story's simple but makes a lot of sense in a world where older folks often feel marginalized and struggle to believe they're maintaining lives of meaning. Here's my one, huge complaint. You don't have to be a genius to not walk in the direction of the traffic on rural roads. Vehicles are approaching from behind - in other words, you can't see what's coming - at high rates of speed. You can be killed in an instant by someone who's texting, otherwise distracted or impaired. The NHTSA (National Highway Traffic Safety Administration) website states, "If there is no sidewalk, walk facing traffic and as far from traffic as possible." How many people were involved in the production of this film which promotes a highly stupid and dangerous practice?
