SOAP (1977-81)
Soap, a primetime parody of soap operas that ran during the late 1970s, captured America’s loosening morals regarding sex, social class, and, um, exorcisms — all in a winking meta-package of insane serialized plots. So it’s no surprise the show ended with a bevy of loose ends, like a dad catching his wife and son in bed, and the main character facing execution by a communist firing squad.
