The Addams Family was, in its own strange way, the healthiest TV family ever presented. The mother and father are utterly smitten with one another. They dote on their children and pay meticulous attention to their upbringing. The children, for their part, are respectful of their elders but brim-full of curiosity and mischief. The grandmother and uncle are loved and respected. Extended family members are admired and included. The butler shows great devotion to his employers, who repay him by providing a loving family. Thing (whatever it is) is appreciated for his omnipresent helpfulness. And visitors are always welcome and treated with the utmost courtesy.
The macabre touches are fun, and provide the fish-out-of-water running gag of outsiders trying to cope with the Addams' ghoulish world, but it's the relationships that make The Addams Family tick. Current sit-coms, with their focus on deception and underhanded tricks, would do well to emulate the Addamses.
