The Addams Family is the creation of American cartoonist Charles Addams. A satirical inversion of the ideal of the perfect American nuclear family, they are an eccentric wealthy family who delight in everything grotesque and macabre, and are never really aware that people find them bizarre or frightening. In fact, they themselves are often terrified by "normal" people.
Basically an updated-for-the-90's version of the original Addams Family show. The family remains the same: Gomez, Morticia, Wednesday, Pugsley, Uncle Fester, Granmama, Lurch, Thing, and Cousin Itt. They're still spooky, and they still have a lot of neighbors and other outsiders who show up and get freaked out by the family's macabre shenanigans.
