Not going to read through 60 pages of posts but I think an area, if not a "land", devoted to The Grid from TRON would be fantastic. Don't tell me about box office too, TRON was a cult classic and Legacy was a visual splendour.
With last year's ElecTRONica and the new DisneyXD TRON series out now, it proves that it has legs if not muscle. Make a dedicated land though with the use of neon and tech and have a RSR-style ride but based on a light cycle battle and you have a keeper. You can even have a Jedi Academy type attraction for kids (and adults) where you are suited up and have to battle one of CLU's bad guys. Toss in an inside roller coaster based on the sky battle and a TRON dance party at night like the End of Line club for the teens and cool parents...I'm there!
Problem is though, it would almost have to be an inside land though...can't do The Grid justice in daylight. That or you could have the outside facades like like Flynn's Arcade and the ENCOM HQ...and at night it transforms into The Grid with lights in the pavement and on the building exteriors.
TRON, like it or not, was an ORIGINAL Disney movie...and almost 30 years after it came out it spawned a sequel and a TV series...not bad. And there is so, so much more you could do with it since Olivia Wilde, Bruce Boxleiner, and even Jeff Bridges (maybe) all seem to be cool in reprising their parts in future movies or the series and games. And it will never go out of style, in my opinion.
