Here's a technological sound-and-light show that is sensational and brainy, stylish, and fun.

The story is simple, as befits a movie that's more about visual flash, technical bravura, and ideas than plot and character development. TRON turns into an action-oriented endeavor, with characters attempting to make their way through the video game inspired landscape of the mainframe to the goal that will achieve victory.

Tron's thematic overtures have a certain silly charm, enhancing rather than detracting from its core virtues. What really makes Tron work is an astonishing sense of design.

Jeff Bridges seems to be the only one having fun, playing a videogame designer who gets sucked into a Day-Glo world of his own creation. It’s like Alice in Wonderland acted out on a kids’ Lite-Brite toy.

Dazzling but lightweight epic about a young scientist kidnapped into a computer, where he battles an evil master control program that runs the place like an electronic fascist. Has some tantalizing moments, as when computer-generated characters debate the religious question of whether users really exist. In the end, though, it's squarely in the old Walt Disney tradition of anthropomorphizing everything in sight, only this time it's circuits (instead of cuddly animals) that look and talk like people.
