I received the Blu-ray disks today. I've watched about one half of Part I. I'm sorry to say that I'm a little disappointed. I'm far from being blown away by it. Now I know I was expecting too much, but I was still hoping for more than this. The biggest difference I can see is that the movie is "brighter". Detail is not that much better. There is still a lot of graininess. Is it terrible? No. But if I had not known it was a Blu-ray disk, I'd think it was a DVD. Basically it looks like the DVD version with contrast and brightness turned up on my HDTV. I'll have to watch all the films in their entirety. Maybe I'm being too harsh, and just expecting way too much from a 35+ year old movie.
