"The Sharpshooter" introduced not only the main characters, setting and back story for THE RIFLEMAN series, but also established its thematic distinctions from other popular western adventure programs produced during the Golden Age of television. To be sure, the staples of the genre inform THE RIFLEMAN's storylines—law and order, right and wrong, pioneer spirit and rugged individualism—but the central themes revolve around the father and son relationship—the first primetime television series to portray a single parent raising a child alone—and nuanced morality plays that explored human nobility and very human frailties, foibles and failings, as well as the archetypal white-hatted good guys and black hatted bad guys and outlaws.
