I just got done watching the 4K/UHD release of this classic movie in which the Mbps average rate is even lower than Rio Bravo. I suspect there will be complaints about it too. I don't have the 2021 Blu-ray, but I'm not sure this 4K/UHD is a significant improvement over that Blu-ray. Somebody...
I can't wait until my 4K/UHD arrives because my last physical media purchase of this movie was the 2002 DVD. It's going to be a significant upgrade for me.
