I am thinking about making a regrade of the new UHD Transfers of LOTR, so they look like the DVDs, in terms of sharpness and definition would it be worth it or should i stick to this version?
I would go with the UHD versions. They are definitely improvements.
No.
I was talking about the color grading which I think is an improvement over the original. It still has way too much DNR and EE though.
