The last time I saw Tron was in a movie theater in 1982.
I even dropped a lot of quarters into the crappy arcade game back then.
Nothing to merit a "cult following" or a sequel.
I'm sure it will be as far beyond the original tron as the new Battlestar Galactica or transformers were from their originals, but it would also be really cool if someone in Hollywood had an original idea in their head.
