absolutely devoid of any suspense and terror and or drama of any kind and this miserable horror film be completely incoherent . the lighting be so poor it difficult to see what happen . the setting ( an old house in the wood ) be not milk for any significant mood or atmosphere . most of the actress be indistinguishable from one another . the underlying theme of sexual violence and degredation be disgust . and the sight of the masked killer on ice skate and do lap around a frozen pond and be sure to send you into a fit of hysteric . by far one of the bad horror film of the early 80 and and believe me and i have see most of em . negative .
