Well this is why award shows are shit, because all the films I’d prefer to win just aren’t the kind of films that are nominated for those kind of things, which usually come about via months of aggressive campaigning and internal Hollywood politics, far more than objective merit...
But since you asked, my personal top films of that year would be I, Daniel Blake, Under the Shadow, Hunt for the Wilderpeople, Train to Busan and The Witch, all of which are either British indies, comedies or horrors, and thus all by default things that would never get a sniff...
And I didn’t dislike either La La or Moonlight, they were both good, but you knew instantly that both would be huge contenders just because of what they were about, and when they came out (invariably about a week before the actual awards are given out, which is de rigor now for some reason) .. which is something you could also say about Green Book, too.
