It's part of Twilight Zone folklore canon that The Monsters are Due on Maple Street is an allegory on McCarthyism, people getting hysterical for unjustified reasons, unfounded prejudices. That's fine and highly admirable. It's a real socially minded episode.
But, the realness becomes sci-fi and sort of unrealistic when the ending has aliens proudly stating they're responsible for starting the mayhem. Okay, fine, but really if aliens were to be gremlin like and tinker with the electricity system of those who look suspicious etc, then you can understand why people will get into a state of panic and hysteria!! Oh well, at least these aliens can speak speak English with perfect American accents.
