I warned you about the Tysons Atmos screen! :lol:
Not sure I'd blame Atmos - I'd blame that theater. I saw "PR" and "Gravity" Atmos at Kingstowne - they were loud but not LOUD!!!!! like "Die Hard" was at the Tysons Atmos screen. I suspect they just like to crank it to 11 there...
One word of possible warning: bring earplugs! I saw "Good Day to Die Hard" at the Tysons Atmos screen and it was the loudest movie I'd ever heard. That might've been an anomaly - or they might always keep it cranked up like that!
I'm one to often get nauseous at shaky-cam films - anything from Paul Greengrass, "Blair Witch", "Battle: LA" all did me in! - but I had no problem with "Gravity". Saw it 3D on a big Regal "RPX" screen and didn't experience any motion sickness issues, thankfully!
