In many ways, Tron is actually a very good movie (at least in my opinion ;) ) What I like is the soundtrack by Wendy Carlos, whose musical work I've been familiar with since my teenage years, and the philosophical undertone of the movie, which suggests that, like the computer world of Tron, humanity is a form of organic computer in which we individuals are "bytes," interacting with each other, sharing, storing and creating data that allow our collective "program" to grow and be improved upon. (This, to me, is the meaning of the last scene in the movie, when we look over the sped-up cityscape at night.)
BTW, I don't normally feature or remark about tribute videos, but I will say that I rather enjoyed watching this video that sets scenes from Tron to the Eiffel 65 song, Blue (Da Ba Dee).
Tron: If you are a user, then everything you've done has been according to a plan.
Kevin Flynn: Ha! You wish!
