I think some of the dialogue is a good bit clearer on the blu-ray. There are a number of lines I couldn’t make out after six viewings in the theater that are clear as day on the disc.
I second this. On my first viewing I didn’t hear the Obi wan line at all. Second time I had to really struggle to hear it and only did because I was told about it and knew to listen. On the bluray, clear as day.
