This was amazing!!! The music is great, the design of the film is remarkable while maintaining the evolution from the original, and I am so happy to see the story continue from the first movie. The de-age effects on Jeff Bridges alter ego in the arena looks great too.
This seems so much in spirit of the original that I can't see them not using some of the old themes. At first I was skeptical about Daft Punk doing the music, thinking of other groups I thought could do better jobs, but they proved me wrong with this trailer. The digitized crackling noises were such an awesome touch, and something I never would have thought of.
One thing I have yet to see or hear about is if the TRON program will be seen or mentioned in this new movie. ALAN-1 is a part of it, so hopefully TRON will be as well. Maybe CLU will see a glass jar with a hologram of TRON banging on the side saying 'LET ME OUT!' up in the Dudes apartment!
