I was very disappointed with Legacy. Flynn went from a go get em type character to a recluse guru with about as much get up and go as a wet kipper.
The original out did Legacy on so many levels. The music score on the previous Tron was vastly superior to Daft Punks monotonous beats which rarely hit any other level. The scenery of the original was something we'd never seen before, yet Legacy was so real. Water was water, buildings were buildings. Everything was sooo physical whereas the previous movie with it's limited tech lead you to believe you were in a different world made of pure energy.
The original was a partial flop at the movies cos people just didn't get the concept of a man going into a computer world. Cripes, most people then probably hadn't even seen a computer!
I think Disney tried to correct a few things from the original that probably didn't need correcting and dumbed it down. Everyones seen a computer now and with more adventurous movies around such as Avatar etc, people are more willing to believe in the more imaginative movies.
I think Disney should have had a bit more faith in the viewing public. With rumblings around and a teaser trailer for a possible Tron 3, Disney have another opportunity to build on the original not take a step backwards as with Legacy.
Oh, and word is "Flynn Lives!"
