Gave this a second viewing last night, and was even more pleased than the first time. I cranked it up a bit (still just -11dB) and the bottom end was incredibly deep. Those 18s were shaking my pants and thumping my chest at various moments. Incredible impact!
The video was loaded with verisimilitude; so much so that often I forgot I was viewing something on a screen, and I reacted as though it was happening in the room. My GF hadn't seen it before, and her Eeeks! and screams were frequent as the realistic video and powerful audio wreaked havoc on her nerves.
There were some plot holes, and illogical moments, but I easily put all those nits aside and committed to the total experience. My reward was a stunning sensory and emotionally fulfilling experience.
What I can afford, when I can afford it...
