I'm not sure if I could explain it to anybody significantly younger but... if you were a teenager in 1982, Tron was very likely the first thing that turned you into a big computer nerd.
Well that and Pong.
Ergo, this is a moment twenty eight years in the making. If there's a geek heaven, I'm in it.

I thought that Jeff Bridges looked old, then I realized.. he is, compared to when Tron the first came out. I'm looking forward to it.
disney has a pretty bad record with scifi, I cant think of a success, & there are failures like tron/black hole. yes tron was a huge commercial flop at the time as I recall. I wonder if it has recouped losses from geek views on dvd.
