The very last segment of this series to be directed by Hitchcock personally (he later did the first show in "The Alfred Hitchcock Hour") is a brilliant exercise in excruciating suspense, but it's more than that. How expertly, and how swiftly, Hitchcock really nails America's hideous and all-pervading gun culture! Machismo has even infected a five-year-old as he runs around playing "war" games with his friends and talking about killing someone. The world in which this incipient assassin operates is depicted sharply - the bland, anonymous supermarket-and-suburbia setting is just right for repressed violence, a place where grown men are dominated by their ghastly spoiled brats and where the most likely victim of Jackie's urge to kill is the underpaid and under-appreciated African-American maid. The untypical seriousness of Hitchcock's wrap-up remarks is highly appropriate.
