One of the things that made “The Simpsons” stand out from other animated shows at the time was its devotion to a recognizable sitcom universe. The Simpsons live in a bland, middle-class American town in a rundown suburban house. The mother is a housewife, the father works at the local power plant, the children attend public schools. In the show’s early days, Homer (Dan Castellaneta) wasn’t a cartoon idiot and more of a not-so-bright moron, obsessed with his status and boss. The Simpsons, however, are a bit more raw and raw than the sitcom characters that came before them; The Simpsons say “damn,” father strangles his son, son is a saboteur and troublemaker, daughter is an unrecognized suffering genius.
Massive cartoon violence wasn’t part of “The Simpsons” until you watched “Itchy & Scratchy,” an animated parody. John Swartzwelder felt that, in making those segments, the show could be as undercut and outrageous as possible. Indeed, in describing the show as bad for Bart and Lisa, Swartzwelder says he can slip terrible things past the censors. He say:
“We could show the kids horrible things at home, as long as we first depicted them for the children of the Simpsons. Somehow, this extra step drew critics. we were confused and burned the crowd with torches We agreed with them that this was wrong to show the children.
