"There ought to be a warning attached to the video release of "Aliens," the sequel to the 1979 sci-fi thriller "Alien." It should read: "Warning. Not To Be Viewed Alone, Nor After 11 p.m. Otherwise, Tranquil Sleep Cannot Be Guaranteed." Because that's how I watched this remarkable thriller -- late at night and alone. I found it, quite simply, terrifying -- one of the scariest movies since "The Exorcist." And one of the best of this type. Translated to video, "Aliens" is not quite as terrifying as it was in theaters, but the suspense, drama and horror are there nonetheless. Sigourney Weaver, that willowy, captivating young star, returns as the sole survivor of the earlier space mission. She's been asleep for 57 years when she's returned to Earth. Why the technology hasn't changed too much in half a century is about the only unanswered question in this otherwise near-perfect thriller."
