First things first. There is absolutely no need for this to be 3½ hours long. It follows the story of the ambitious "Ernest" (Leonardo DiCaprio) who arrives at the Osage home of his venal uncle "King" (Robert De Niro) who encourages him to ingratiate himself with the wealthy, indigenous, population. He ends up meeting and driving the independent, no-nonsense, "Mollie" (Lily Gladstone) and after a while she starts to fall for his charismatic charms, they fall in love and marry. Though he does love his wife, "Ernest" proves to be a rather fickle and violent man who loves money more - and at the behest of his outwardly benign relative starts to implement schemes that will ensure the rights to the oil well heads move swiftly - and frequently brutally - to more "suitable" owners. This sudden spate of "accidents" and killings and the prudent action of the fearful local council alert the authorities in Washington who despatch a team of FBI agents led by the tenacious "White" (Jesse Plemons) to get to the bottom of things. Perhaps the "King" house of cards might now be becoming just a but precarious? DiCaprio is very effective here. He plays well a man who juggles internal demons and conflicts as he is cleverly manipulated by an on-form, slightly menacing, De Niro. It's Gladstone who steals the show for me, though. She plays the role of the decent and loving - but shrewd and savvy - "Mollie" strongly. As she starts to become a victim of her husband's avarice she exudes a sense of desperation that is both pleading and dignified and her struggle is potently illustrative of just how far the "white" man was prepared to go to get to - and keep - the money. The film is beautifully shot with a plausible look that helps generate for the audience a true sense of just how this outwardly genteel and civilised society was really anything but and the writing clearly interweaves the clandestine aspects of the the plot with the more noble ones. Perhaps sacrilegious to say, though, but at times it does really drag. I felt it could easily have lost an hour, condensed the story and immersed us more quickly in the characterisations and not really suffered. It's a good film, but it's not a great film and unlike Scorsese's far better "Irishman" (2019), I'm not at all sure I will rush to watch it again.
