It misses the point of Addams Family, I feel, which is a counter culture relative to the normal mainstream family. Once you put the Addams Family in a society where supernatural and horror is the norm, then what's the point of the show? Certainly there is a whole supernatural world from where the Addams Family came from, but they're always in the background of the stories for a reason - once the Addamses are no longer the outliers in the community, they lose their appeal.
