Although Stephen King himself wrote the screenplay for this horror exercise, Sleepwalkers is no better or worse than the many quickie adaptations that have been produced without the author's direct input. It's merely an adequate outing full of cool ideas whose execution lacks enough atmosphere or true psychological insight to frighten or even unsettle most audiences. Likable Twin Peaks vet Madchen Amick seems wasted as the good-girl protagonist; Alice Krige is far more alluring as the matriarchal vampire whose feline sensuality sets up all sorts of intriguing Oedipal conflicts with her son. Unfortunately, director Mick Garris doesn't milk such subtext as much as he should. He seems more interested in showing us his titular shape-shifters turning things invisible and slipping into Beauty and the Beast drag. Still, for all its quotidian special effects and familiar thrills, Sleepwalkers is fairly entertaining. A bit of campy humor and a few celebrity cameos give it just enough genial charm to tip the scales in favor of watchability.
