Just picked up the Blu ray set today.
I watched a New Hope first.
And it's hands down by far and away the best it has ever looked on home video(In my opinion of course).
I also have Blu rays for Close Encounters, A Bridge Too Far, Saturday Night Fever,The Deep and Smoky and the Bandit which are other films from 77'.
And this transfer for A New Hope blows each and every one of those away.
