Right, Robert Harris doesn't "get" Blu-ray, but they do. It is to laugh. What did these people do before Blu-ray? I know what Robert Harris did before Blu-ray. The sum total of these people's knowledge is - wait for it - what they've read on the Internet. They have no experience with film...
I will also say that High Noon looked very good on my 55-inch Samsung, which is a GREAT set. Very sharp, very detailed. Again, on larger screens the anomalies may be there, but they're not there on smaller screens. And re the opening sequence with the credits - it's an optical.
