If you like horror films this one delivers the goods well enough, with plenty of special effects and at least an attempt to rationalise the thing with a psychological basis. Ally Sheedy's low-key performance tends to increase the effect, making her the fulcrum around which everything moves, but is this really the sort of role she wants to play? The other performances are more than acceptable, but I won't be rushing to see it again.
