Ghost in the Machine (1993). Really bad. From IMDb: "Karl, a technician in a computer shop, is also the 'Address Book Killer,' who obtains the names of his victims from stolen address books. Terry and her son Josh come into the store to price software, and a salesman uses Terry's address book to demonstrate a hand-held scanner. Karl obtains the file, and while driving to Terry's house that night in a heavy rainstorm, his car runs off the road and lands upside down in a cemetery. While Karl is undergoing a CAT scan at the hospital, a surge of lightning courses through the building, and Karl's soul is transformed into electrical energy. Karl uses the electrical grid and computer networks to continue his killing spree." More IMDb: "The whole idea of the killer going into electricity in general is obviously the most unrealistic thing in the entire film, but it is stretched to cover almost the entire movie from beginning to end, which is what shows most clearly the fact that the movie is based on the emergence of the world wide web. It's kind of a what-if thriller about what would happen if a psychotic killer was accidentally released into the electricity based communications system that is the internet and was then able to defy all laws of logic and physics and who knows what else, and if he had somehow developed this overwhelming passion to kill a certain woman and her family and friends for committing the crime of leaving her address book at the computer shop.
