Well, my first Blu-ray ended up being Dark Knight. The PQ is great, even on my non-1080P TV, but the flip-flopping between aspect ratios was a little annoying. The SQ was amazing! A definite improvement over standard DVD's.
Oh, and an excellent movie. I've already watched it twice and if I didn't have a bunch of other movies to watch I would be watching it a couple more times this weekend.
