This movie is pretty much perfect. Anjelica Huston, Christina Ricci, and Christopher Lloyd excel in their performances as the most noticable of the family members. They know how to act in a dark comedy like this, where a mother might have to take away the knife her daughter is chasing the younger brother around with. And hand her an axe in replacement.
The movie has about three sub-plots. The first involves Morticia and Gomez, the parents, who just had a baby and are having to deal with all three of their children at once ( Wednesday and Pugsley, the children, are infatuated with disposing of the infant ).
While the children are plotting away, a nanny is hired. Her name is Debbie, played very well by Joan Cusack. Unbeknownst to the family, she is a criminal who marries rich men and then kills them, earning her a famous black-widow reputation. The second sub-plot involves her advances towards a relationship with Uncle Fester, one of the world's richest men.
The third sub-plot is Debbie's decision that Wednesday and Pugsley be sent to summer camp, which is basically the Addams's vision of Hell. Or Heaven. Whichever they like the least.
The movie is filled with hilarious one-liners and events, and the Addamses will charm almost anyone with their twisted, morbid lives.
