Watched this last night. It looked pretty damn good, and I enjoyed the new 5.1 mix. I thought the film was good, but the historical significance of the film is more interesting than the story it tells. Very good bonus content on the disc, too.
I'm glad my first viewing was on a 96" projection...
Having never seen The Robe, I'm looking forward to finally seeing it, and in the best non-theatrical experience possible. I'm glad they've done what they could.
