I am looking for a short film. It wasn't very long—probably under 30 minutes. In it, a subway runs through a boy's bedroom. He complains to city officials, who tell him that their computer, which "is never wrong," placed the subway station there. The boy finds out said computer is a piece of junk that never worked in the first place, and its decisions are actually made by an old man who, upon talking to the boy, moves the subway station elsewhere.
