This is one of the few Oscars where I've actually heard of, seen, and liked a number of the movies nominated. Joker, 1917, and Marriage Story are all phenomenal films for very different reasons, they earned their multiple nominations.
(If you want to nitpick, I'd argue Joker shouldn't get that best screenplay nomination, because the minor problems with that movie are a result of the script skipping some necessary world-building. But when the whole movie turns out so well, it's hard to justify giving that slot to someone else.)
But Trump's bound to tweet about one of the movies he likes after it wins, and then we're gonna see some heads exploding over in Hollywood.
