I agree that lighting is a huge factor. In my theater I have 4 zones - front (2 cans), back (4 cans), 3 sconces, and the rope lighting. They are all controlled through a lutron switch that is programmed into my remote. So I hit play and the lights dim, hit pause and the lights come up. I never go completely dark for many of the reasons BMXtrix mentions. The rope lighting in my theater takes care of the 'see where I am walking' issue.
