I dont care about grain or not, i tend to prefer grain be left intact. But this thread, even with the complaining, is a good one because a lot of people have the bluray and might be thinking of picking this version up as well, or instead, and there's a lot to ask about the new version- did they remaster it? Are there any features in this version not in the HD DVD version (or vice versa)? Reasonable questions.
As for DNR/Grain, I wished CEs would put DNR settings either in the TV or in the player. This would let people who hate grain reduce it themselves, and give people who don't hate it the chance to enjoy it. Not that this will happen any time soon.
