Suspenseful thriller about an unmarried couple who sublet their Victorian home to a menacing tenant. Hitchcockian tale gradually exposes their vulnerability so we share in the frustration of the young couple. Script also raises some interesting questions about California tenant laws. What makes this thriller so convincing is the unexpected path the story ultimately takes. Melanie Griffith shines as the more rational mind in the yuppie couple and Michael Keaton is effectively manipulative as Carter Hayes, a psychopathic con artist.
