I guess my "go to" demo movie would be Oblivion. Like djbluemax1 said, the picture quality is incredibly pristine. I love the score and really like the movie. And yeah, the bass is quite impressive.
A safe bet is always the "emergence scene" from WotW. Can't go wrong there. If one is looking into horror, I guess I'd put in The Conjuring (when I first saw it, I jumped a foot at the pounding doors scene(s)).
