Tron ★★★½

Yes, this film is cheesy, and doesn't really understand how computers work, and is paced with all the energy of a snail race. But it really deserves credit -- not just for the oft-mentioned CG effects and environments, but for the mental leap required simply for envisioning the world of computers and programs the way it does. Entertaining and even thought-provoking at times, TRON holds up better than a lot of people give it credit for.
