What was the reason for the use of DVNR on the blu ray. I mean if they restored the movies and the quality was there for all to see why ruin it by removing an integral part of the image and what the Cinematographer intended us to see?

The film prints i saw in theaters way back when were very fine grain anyway and not grain heavy except in the scenes where you had optical generations for the special effects.

There was zero need for Universal to DVNR a film that was not so old. I mean 1985 with the first film was the oldest.
