As for Unforgiven, and other classic movies, I think these can look stunning on Blu-ray, probably the best they've ever been, and the effect is usually more noticeable than say a recent movie, which all look nice and clean and sharp, even on DVD. As long as studios put in the effort to properly remaster the films, they will look great on Blu-ray, and you will spot an amazing amount of differences if you compare it to the DVD version. Some people may not like the grain or color differences compared to recent movies, but that's how these classic films were filmed and how they were meant to be seen.
Here's the review of Unforgiven on Blu-ray, with screen captures, so you can judge for yourself:

It's just a shame they didn't put the same amount of effort into Lord of the Rings movies, as otherwise it would be must buy.
