All it requires is brand new transfer taken from original sources using current technology, original aspect ratio presented anamorphic, and colours that remain untampered with and true to the original release of the movie.
Heck, I dont even mind if there is a little bit of film dust and scratches as long as the definition is there, and we don't get the 'ghosting' and 'peculiar' grain that appears on this latest offering.
Oh and a choice of the original sound mixes, uncompressed, would be nice too!
Not too much to ask is it?
