A superb concept about being trapped in an advanced arcade game / supercomputer. It was the first film that mixed computer generated effects, traditional animation and live action into something unique and the universe we are introduced to here has never been copied. I like the mix of cold bleak color on the people in this universe and the suits of either blue (for the heroes) or red (for the bad guys).
There is some level of merit in the time this came out. 1982 is 2 years before Neuromancer was published. Even if this is mainly fantasy and quite harmeless politically, it did invite everyone to pose questions when there was no reference for (and no way to visualise) what cyberspace could be. This went way beyond cybernetics. It worked mainly due to its simple powerfull aesthetic. It's a great visual achievement.
Tron's costum design is corny and laughable. The plot is poorly structured and confusing. I thought that the performances were really bad, when Jeff Bridges is in the real world he is ok, but when he is in the digital world, he tries to look like a robot or something and he miserably fails. So, on overall, Tron is not a good movie, but if you are in the mood to watch a sci-fi cult , you can appreciate it, like I did.
An interesting fact is that this wasn't allowed to be up for a special FX award as using computers was seen as cheating. The visuals still hold up even now with a respectful narrative and a great performance for Jeff Bridges. A visually pleasing film with strong characters, whats not to like?
