I have the possibility to watch this movie at home, however, despite the Martin Scorsese direction and Leonardo DiCaprio as the main protagonist (who are my favorites), I don't manage to find time to watch the movie at once.
Of Leonardo DiCaprio's films, the strongest impression on me was the cruel film The Revenant, for which Leonardo won the Oscar for best actor, (finally).
If you recommend Killers of the Flower Moon, I have to find 3.5 hours to watch it 😀
