The screen was bigger than our house, each seat had an built in sub-woofer and there were 12,000 (yes 12 thousand) watts of sound in total.
The experience was almost completely immersive. I think I pulled my rotator cuff during one of the fight scenes.
The movie itself was possibly the best action/science-fiction film I've seen. Spectacular story, effects, acting and a pretty decent soundtrack.
It was basically this trailer for 105 minutes.
