The storyline for Kronos was a mature science fiction about an alien machine sucking up energy as it lumbered across Mexico to LA after landing. Of course, with a $160,000 budget said lumbering involved stock footage taken from The Rains of Ranchipur and The Revolt of Mamie Stover (Trailers from Hell), but the special effects were above average and ambitious for their time involving stop motion, mattes, and animation.
