Stepfather, The (1987, USA) C-89m. **½ D: Joseph Ruben. Starring Terry O'Quinn, Jill Schoelen, Shelley Hack, Charles Lanyer, Stephen Shellen, Stephen E. Miller. Contrived, partially effective thriller about psychopath O'Quinn, who has just killed his entire family and moves on to a new one, obviously having wiped out all traces. How long does it take his anxious stepdaughter to find out about him? Story plays out with these typical plot coincindences, but O'Quinn's performance is convincing. Followed by two sequels.
