"DiCaprio and De Niro are brilliant, but it is relative unknown Lily Gladstone who is truly extraordinary."
— Clarisse Loughrey, The Independent
"Both a staggering piece of cinema and an urgent social probe and trial that is universal despite its historic and cultural specificity."
— Namrata Joshi, The New Indian Express
"Martin Scorsese film is a Western, a true-crime thriller, a character study, all of which segue into a sprawling origin story of how a nation was born."
— Shubhra Gupta, The Indian Express
"This is an utterly absorbing film, a story that Scorsese sees as a secret history of American power, a hidden violence epidemic polluting the water table of humanity."
— Peter Bradshaw, The Guardian
"It's anchored by performances from Leonardo DiCaprio and Robert de Niro that both rank among their best, but the soul of the movie belongs to Lily Gladstone, who broke out in 2016's Certain Women."
— Esther Zuckerman, The Daily Beast
"Killers of the Flower Moon is vast and vital in its scale, purpose and emotional scope, a Western-thriller and ensemble piece that is every bit a Scorsese crime picture as one can dare to imagine."
— Tomris Laffly, TheWrap
"The three-and-a-half-hour running time is fully justified in an escalating tragedy that never loosens its grip — a sordid illustration of historical erasure with echoes in today’s bitterly divisive political gamesmanship."
— David Rooney, The Hollywood Reporter
"Killers of the Flower Moon suggests film-makers should keep on keeping on. I’d even put my cowboy boot on the line and declare this one of the best Westerns ever made and almost certainly the best film of 2023 so far."
— Charlotte O'Sullivan, London Evening Standard
"It’s Gladstone who provides the film’s centre of gravity. She gives one of the most extraordinary performances by a woman in any of Scorsese’s movies. She is serene but not saintly; a figure of tragedy with a fire in her belly."
— Clarisse Loughrey, Independent (UK)
"[A picture] brimming with reverence for a culture that survived a horrible trauma as it is filled with exhilarating flourishes, film history references, and explorations of the faultline between the sacred and profane. And yes: It’s a masterpiece."
— David Fear, Rolling Stone
"Lifting his camera to survey the wide open plains of the past, Scorsese extracts an epic Western from horrible real-life crimes committed against the Native American Osage tribe of, latterly, Oklahoma, delivering something biblical, human, yet deeply inhumane."
— Fionnuala Halligan, Screen Daily
"Weaving the Tulsa race riots, the KKK and the Masons into its tapestry, Scorsese’s opus questions the misdeeds of America in the last century while linking them to the pressing issues of today. Addressing racial violence, nationalism, the continued epidemic of missing and murdered Indigenous women and even our lurid obsession with true crime, Killers of the Flower Moon paints a robust picture of a moment in history that invites viewer introspection."
— Jane Crowther, Total Film
