There's a clear love of family and love for children. But some of the Addamses' antics appear mean-spirited.
Knives, swords, and other medieval weapons are frequently visible, but their use is rarely seen; a torture device is used on Morticia (to her pleasure), and Pugsley is strapped into an electric chair. A hand gun is visibly pointed at Gomez. The children, especially Wednesday, use weapons and other sources of pain to try to hurt each other as part of their everyday play. In the end no one gets hurt (although it's unclear if the bad guys are dead at the end).
Strong sexual innuendo, especially between Gomez and Morticia. The couple can be heard having an orgasm while in public. There are several subtle references to sadomasochism, and a quick reference to child molestation relating to Uncle Fester. Much of this will go over the head of young viewers.
Swearing includes "damn" and "hell."
Clear visible ads for Tombstone Pizza and Fedex. Sally Jessy Raphael is briefly featured.
Gomez is occasionally seen smoking a cigar. Brief adult consumption of hard alcohol.
