We watched '2012' as well last night on my newly re-calibrated Audyssey system on my Denon. At -10 Db, the sound track was very good & mercifully not overdone in the LFE department that was most welcome for a change. Given the myriad of massive catastrophic destruction scenes, the sound guys could have gone over the top, but thankfully they restrained themselves.
Overall an OK movie although somewhat long due to a convoluted plot. Unfortunately, the never ending life & death sub-plots throughout made it fatiguing for me to sit through. Visual special effects of the earth's crust self-destructing were quite spectacular & mostly very realistic looking.
This BD was worth the 3 bucks that I paid during the close out of our last local video store.
