on Tuesdays, $6 for any ticket, any time of day.
Any other time, $7 w/military ID discount (2D). Haven't tried with 3D, I imagine discount brings it to about $9ish. I think 3D standard rates here are about $12 or $13.
I will be watching the new Tron in 3D. Yes, yes I will.
IIRC, the new Tron used the same 3D technology used for Avatar - which, btw, is above and beyond that annoying and gimmicky 3D of the past generations, and is actually adds more to the experience. The visuals have real depth, which is something I absolutely love. Fast motion, like in real life, can be blurry except for the one spot in focus, just like with real eyes. Another reason why I hate 120hz TV viewing, no blur makes it look artificial and annoying.
