“If viewers can make their peace with the runtime, the film is a no-holds-barred history lesson that will be etched in their minds for life. Academy Awards, here we come…”

The New York Times called the film “an unsettling masterpiece… As the oil begins to gurgle and then to gush, it splatters a half-dozen Osage men who’ve started to dance ecstatically at the discovery, their bodies slicked with petroleum — a harbinger of the blood that, as Scorsese reminds you in this heartbreaking masterpiece, has long engulfed us all.”

The Standard wrote: “This is a much, much better film than The Irishman, which unapologetically focused on the male gangsters with whom Scorsese will forever be most closely associated. It looks beautiful, features a wealth of great performances, and tells a tale that needed to be told, very well indeed. It is – genuinely – his best since The Wolf of Wall Street. Not a line that would make it onto those posters, perhaps, but impressive nonetheless.”
