Remake TRON?
Update the original concept in today's time period?
Um...
NO.
TRON is what TRON is in large part because of when it came out and the time period it was set. It was poorly marketed and many people didn't go see it because of that (and many were just not ready for such a concept yet), so it flopped at the box office. But pretty much everything that gave TRON it's heart and soul is based in EXACTLY what the film was and is - AND WHEN it took place.
You can't respectfully remake this film without horribly altering what it is and WHY it is such a great film.
Remakes can be a good thing. We've all seen great remakes before I'm sure. We've also seen many not so great remakes. Not going to get in to which ones were good and which ones didn't quite work. But TRON cannot be remade and still be what TRON is. And what TRON is, is why we all gather here together as we do. We all LOVE it.
Nope. This can't work.
I'm also very happy to see others comparing this to the Sci-Fi's abomination of Battlestar Galactica with their remade series of the same name. That was my FIRST thought on this matter. Actually, a remade BSG could have worked if they followed the original premise and just did it right. BSG was not really dependent on any time era. BUT they didn't and that's another argument all together.
I respect the opinions of those who believe a remake of TRON can be a good thing. As much as I just want to flat out tell you how very wrong you are... I can't. We've all got our interests and opinions and tastes. Some may just get excited about anything new that has the name "TRON" on it. Some may very well believe that a new TRON can be great and exciting and they're keeping "an open mind" about it. I do not share in this excitement, but respect the thoughts of those who do.
To me, TRON modernized HAS to be a sequel set in today's time, with it's foundation clearly laid in what took place in 1982. There are SOOOOOO many cool things that could be done with a sequel. It is very conceivable that a TRON sequel could even be something that people who've never seen TRON would find interest in and want to go see. There is no need to remake this classic work of greatness. Profit can be made by building on what's already established...
Oh, why am I wasting my precious time?
Disney will do anything to turn an easy profit, regardless of how it messes up what TRON is (both in concept and what's cool about it). It's all about the profit, regardless of the original fan base. The remade TRON will not be geared toward the fans of the REAL TRON - we are all throwaways in their eyes. A (relatively) low budget production called TRON jazzed up with some trendy characters and modern themes and geared toward the 16-24 age group will turn an easy profit. It doesn't have to be huge - it just has to make enough money to be successful. These days they'll have no problem turning a much greater profit than the original, and with far less substance behind it. As with any business - the bottom line is turning the profit. That is good business. Too bad TRON has to be whore'd out to do it though

Yeah - that's how I feel about it.
No open mind here - what a surprise, right?

A modernized remake of TRON is just a bad idea. It will not be an homage to a great film, but rather a modernized regurgitation of today's popular and trendy ideas & cyber-action sequences mixed in with some weakly implemented elements of the original TRON (and some comedic moments) that won't be worth the processors utilized in it's making. And as much as I hate to say this, there will still be people who love it (the remake that is). YUCK!
There. I'm pretty sure that's all the TRON remake will be. Though it will be admired by many (sad to say), it will be exactly what I've nut-shelled here.
