Killers of the Flower Moon is a three-hander on an epic canvas, a corrosive analysis of America’s colonialist and capitalist excesses as refracted through a marital melodrama in the vein of George Cukor’s Gaslight or Alfred Hitchcock’s Suspicion. As those artists did in those films, Scorsese cultivates a spellbinding air of uncertainty, even though it’s clear from the moment Ernest courts Mollie at his uncle’s insistence that little good will come from their pairing.
