I didn't find myself laughing quite as often as with some of Keaton's later films, but I was smiling the whole time. The three-time-period premise is a lot of fun. It also has the falling apart car gag which is one of the funniest things Keaton has done.
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."
