Book review : KIRKUS REVIEWS
Though slavishly modeled on Rosemary's Baby--the uptown Manhattan locale, the attractive young couple, the friendly (evil) elderly neighbors--this horror teaser is more silly than scary. But the breezy mindlessness here is easy to take, especially since it can all be read as a macabre (perhaps unintentional) send-up of the jogging/health-food craze.
