This installment in the series manages to be genuinely enjoyable. The birth of baby “Pubert” isn’t exactly a cause for celebration for “Wednesday” (Christina Ricci) or “Pugsley” (Jimmy Workman), and they come to the conclusion that he needs to leave. Simultaneously, parents "Morticia" (Anjelica Huston) and "Gomez" (Raul Julia) decide they need to find someone to care for him, and their search leads them to "Debbie" (Joan Cusack), who quickly focuses her attention on “Uncle Fester” (Christopher Lloyd). The children are then shipped off to a summer camp—one of those places run by people who seem devoted to peace and harmony—where they feel like outsiders among the overly sentimental students led by "Becky" (Christine Baranksi) and resembling characters from "Little House on the Prairie." This sets the stage for some darkly humorous situations as the kids attempt to escape this dreadful place, creating as much chaos as possible along the way while also offering a pointed commentary about the treatment of Native Americans. And speaking of unwelcome guests, it becomes apparent that the nanny has her own sinister side—and “Fester” might be headed toward joining her list of former husbands who have passed away. As usual, Huston is the standout; she doesn't appear often, but when she does, she brings a certain threatening grace to everything. The rest of the cast works well together, and the story includes plenty of silly humor geared towards adults, some mild physical comedy, and “Lurch” (Carel Struycken) is on hand to maintain some semblance of control. There’s considerable care given to the film's visual style, and ultimately I found myself agreeing with the siblings about young "Pubert."
