Yeah, I like the twist that ...
Wow, there was no internet, no home computers, no cell phones when Tron came out. Video games, primitive ones at that, were civilians' only contact with cyber unreality. I think that sets the bar far higher for this one, and frankly - the look in the teaser doesn't seem that far advanced over the original.
But natch, I will see it. The original was, imo, really stupid ... but has a fond place in my heart.
