The Back to the Future blu-ray has a very DNRed look where all the faces in the film look very waxy and ;acking in fine detail. It also suffers from lots of edge enhancement that makes the overall image look very artificial and digital looking.
As the main source for this release I used a high quality DCP transfer that doesn't suffer from DNR or edge enhancement so the film looks much more filmic and pleasant to watch. Hopefully a 4K Ultra HD blu-ray comes out soon and they do it right this time because this amazing film really deserves a new top notch 4k transfer.
