I think Roma, The Favourite, Green Book and Isle of Dogs were the films with real value for this year among Oscar nominees. For the must underrated films for this year for me is "The house that jack built" of Lars fon Trier - you can very rarely see such a good movie about a psychopath. A real masterpiece! I can say the same for "You Were Never Really Here".
