Like blu, I'm also interested in seeing this film by first-time feature director Joseph Kosinski.
I don't know if the Tron story will resonate with me as I have no knowledge of the first one. So, it will depend on the story - of course it always depends on the story and how well the story is told.
Kosinski joins a rather long line of directors who got their break after doing television ads (e.g. Ridley Scott). Videos to some of his best known works and commercials can be found at http://www.josephkosinski.com/main.html
I do think he has a talent for the use of music and sound effects so that is a plus. I really enjoyed Ispec the Apple ad of the future. For those that appreciate The Shining, it is a must to watch.
The downside is that he seems to really into ice-cold modern architecture - that leaves me ... ice-cold. Notice that both Mezzo: Race and the Nike ad feature rather perfect people in their skin-tight bright white outfits with red accents in their futuristic modern habitats. Or note the Desert House video. I'm concerned that his soul seems trapped in a Bang & Olufsen store. But, each to his own.
