I watched this again just yesterday – can you believe it’s 40 years old! I missed it when it first came out; I was one of those kids who wasn't interested in "Space Invaders" or owning an Atari, but I do remember all the talk surrounding Disney’s attempt to enter the computer games market. The plot isn’t really that bad, actually. It borrows heavily from other stories, featuring a very good-looking, young Jeff Bridges ("Flynn"), dressed in 501 jeans, trying to get revenge on "Dillinger" (David Warner), who stole his gaming ideas and climbed the corporate ladder because of them. However, "Dillinger" has now created a "Master Control Programme" – similar to “Forbin Project” from 1970 – and when "Flynn" tries to access this system, he finds himself trapped in a survival game alongside other rebels like "Tron," "Ram," and "Lora." They have to figure out how to destroy the "MCP" before it gets bored with its industrial goals and starts targeting places like the Pentagon and the Kremlin. Considering today’s standards, the visuals seem flat and simple – but there's no denying they were innovative and fast-moving for 1982. The use of light—blue representing good and red representing evil—and the slightly overexposed look, intended to create a different digital world, works pretty well. Although you never really worry about what’s going to happen at the end, it's an enjoyable couple of hours that reminded me that every big tree begins as a tiny seed. The attempts to work technical or gaming terms into the dialogue feel forced, but there's a fun scene with a "bit" that can only respond with yes and no while “Flynn” navigates his quirky vehicle ("Max" from "The Black Hole" (1979)) through a maze of circuits. David Warner isn’t very believable, I never thought he was particularly good – but once it gets going, it's an enjoyable piece of cinematic nostalgia that looked pretty decent on a large screen.
