2 things I was surprised with on transformers:
1. Bass is present in almost every scene! Everytime Prime talks, a robot walks, or pretty much anything that isn't speaking gets a nice dose of bass. At first I thought my receiver's EQ was set bass-heavy by mistake by I had it on tone defeat - awesome

2. Chap 19 (1:55:50) FLOORED me in theaters but for some reason didn't impress me at home. I'm running 2.0 with Paradigm 60's so although I expected more I can understand not getting subwoofer-grade sound. There might be a setting for night-mode (dynamic compression I guess) on the tv I need to check out before getting too disheartened.
Seriously a good all-round great sounding movie.
