Well, one thing that was revealed is that coppola himself didn't supervise or approve the transfer. Supposedly, "a representative from Zoetrope relayed Coppola's wishes re: the transfer to the guys (at Sony, or even inhouse at zoeptrope, have heard both...) doing it..."
Coppola was off shooting his most recent film. (Interestingly the old Criterion LD which many paid over $100 for WAS approved by coppola and looks pretty much exactly like the SB dvd though...)
The point that Xylon and I and many others, (including many review sites) is that the film now looks radically different in many scenes, much darker and with much less color than in all previous versions. We were told that all those versions were wrong, even many if not all the theatrical release prints and this new BD looks much closer to the fabled "answer print" that was the original intention.
Many of us think it looks much worse and even that it all just sounds like an excuse for a botched transfer and a way to avoid a very costly exchange program like with The Fifth Element, (and yes, that release was originally defended as well just as vociferously.)
Just our opinions.
Reread this thread with Xylon's great work. Get the film and see for yourselves. Some like the new look, I would say that from all the sites and forums and reviews I have seen, most don't.
