In a world where cloning boomed in the 1960s, Never Let Me Go prefers to keep its sci-fi setting in the distance (which may turn some off), opting to hold close the relationship between three replicants: Kathy, Tommy and Ruth. Through this trio, the film sends a direct challenge towards our conceptions of love, humanity, being alive and what it means to have lived a life. It guides you through with tenderness, though never holding your hand. It delivers its message with patience, though it never drags. It may not always hit the heart, but it always clips the arteries.
