Filmmakers Sean S. Cunningham and Steve Miner scored hits with several simple Friday the 13th films but tackle a more complex story here with embarrassing results. Cornball script [from a story by Fred Dekker] posits Roger Cobb (William Katt) as a successful horror novelist who moves into the spooky house where he was raised following the suicide of his aunt, as he writes a book based on his war experience in Vietnam.
Cobb immediately experiences odd happenings which play as hallucinations, but which the audience is supposed to believe are real. His estranged TV actress wife Susan (Kay Lenz), shows up, apparently changes into a puffy monster and is killed by Cobb.
Though much of this nonsense is played tongue-in-cheek, an audience can hardly be expected to swallow the screenplay’s arbitrary approach to Cobb’s character. Compounding such credibility problems is a ludicrous subplot with Cobb’s neighbor, a wolf-whistle beauty, Tanya (Mary Stavin).
Cast cannot be faulted, especially lead Katt. The monsters are fake and rubbery, better suited to a comedy than a film in search of scares.
