I don’t mind DNR. Film grain is annoying when you watch an old film on an HD or 4K TV, and it obscures a lot of detail, such as the skin on some characters and some objects in the background. Plus, I don’t want to have to be reminded that I’m watching something that isn’t really happening, I want to watch something that feels as if you’re seeing a real event with your own eyes.
Sure, DNR has its flaws, like how it makes the image quality a little muddy and blurry, but it’s better than having to see these little specks while watching an old movie on an HD or 4K TV all the time.
