"Family Plot" is remembered only for being Hitchcock's last film. The ending to his successful career could be have been more honorable. "Family Plot" is merely a light entertainment movie - nothing more, nothing less. But it works as that. The plot is enjoyable to follow and the members of the cast (especially William Devane) do a creditable job. But remember that the director was no longer at his peak, so don't expect anything in the lines of his masterpieces, like "Vertigo" or "Psycho". And John Williams' barely memorable score pales in comparison with Bernard Herrmann's masterful accomplishments.
