It is showing its age (camerawork, direction, visual effects), but still got its charms. Check for example the husband and wife team who head the family in question, even though the female side appears underused. Christina Ricci is also wonderful as the daughter, and I also liked the Frankenstein-like family butler. These are the only interesting characters, and all others are either uninteresting, badly-developed, annoying, or practically non-existent.
The movie is otherwise quite shallow and very passive, even for a comedy. It's not even funny, especially the first half of it.
