This 1993 sequel starts off with the same sort of hard-sell blackout gags as its predecessor, most of them built around the premise of Gomez (Raul Julia) and Morticia (Anjelica Huston) having another baby. But once Joan Cusack enters the picture as a nanny-cum-serial-killer/gold digger with her eye trained on Fester (Christopher Lloyd) things get livelier, and by the time the movie reaches its centerpieceWednesday (Christina Ricci) and Pugsley (Jimmy Workman) are being shipped off to summer campthe comedy has moved into high gear and become one of the funniest, most mean-spirited satirical assaults on sunny American values since the salad days of W.C. Fields. Paul Rudnick wrote the script, Barry Sonnenfeld directed, and Carol Kane costars as Granny. (JR)
