Just to clarify: When I said that a Paramount transfer engineer told me the DVDs looked exactly like the original prints, that was in 2001. I agreed with the engineer, but it's because at the time I thought the prints had deteriorted. Apparently so did Coppola and Paramount, which is why we now have the "Coppola Restoration."
Note, too, that the folks at Paramount go out of their way in their promtional materials to say that only the first two "Godfather" films were "restored." The third film, apparently in better shape, was only "remastered."
