"It's a Good Life" is a 1953 story by Jerome Bixby, who also wrote It! The Terror From Beyond Space, said to be the inspiration for Alien, and the Star Trek episode "Mirror, Mirror" (the one with evil bearded Spock.) It was made into a famous Twilight Zone episode, and is generally considered among the greatest SF stories ever written. Is "It's a Good Life" about God? Communism? 1950s suburban conformity? Or just about the horror of the self-contained world it creates in its few pages and the terrible realization that it would be possible to survive inside it, for a while?
