“Nightworld” (*1/2 out of four) was a dreary, derivative horror thriller that rips off (yet again) “The Shining” and “Poltergeist” and many others. In a run-down city in Bulgaria, a former cop (Jeremy London) takes a job as a security officer at a historic building but he soon begins to learn of the building’s terrifying history and is visited by a sinister figure (Robert Englund). Reasonably well-directed but story becomes sillier and hokier and gradually decays into sheer corn. Englund would have done better collecting his “Nightmare On Elm Street” royalties rather than starring in dreck like this.
