My four favorite films are my four most recent 5-star ratings.
I found it difficult to sit through a 28-minute piece of propaganda on a subject I don't care about in the slightest. I only got through it by repeating to myself, "Kubrick made this... Kubrick made this..." As I watched, I did my best to spot anything "Kubrick" about it. It was well shot, kind of. The subjects were always in frame and there were a couple competent tracking shots. But the truth is there's just no reason to watch this other than to be able to say "I've seen every Kubrick film."
