It's a real slog, with a cast that mostly can't sing. Mr. Eastwood does not acquit himself well. I do enjoy watching an entire town sink into the mine shafts toward the end...that must have been expensive as hell.
I have to disagree with you about the Blu-ray that Paramount issued a while ago of ONCE UPON A TIME IN THE WEST. Just like the prior double-disc DVD, I think it looks wonderful (although a 4K would be welcome, too). I think they really did give it "the love."
