Peter John Dyer of "Sight & Sound" wrote, "Richard Matheson's script, a good deal more tenuous than its predecessors in the Corman-Poe canon, at least treats its actors generously to props, incantations and quotable lines ... A pity the equation doesn't always add up; there's too much slack, due perhaps to an imbalance between the comedy, which runs riot, and the horror, which trails behind in the wake of previous Corman films."
