"In an age of amazing special effects, "Tron" is a state-of-the-art movie. It generates not just one imaginary computer universe, but a multitude of them. Using computers as their tools, the Disney filmmakers literally have been able to imagine any fictional landscape, and then have it, through an animated computer program. And they integrate their human actors and the wholly imaginary worlds of Tron so cleverly that I never, ever, got the sensation that I was watching some actor standing in front of, or in the middle of, special effects. The characters inhabit this world."
