When oil is discovered in 1920s Oklahoma under Osage Nation land, the Osage people are murdered one by one—until the FBI steps in to unravel the mystery.

Enormous in runtime, theme, and achievement, Killers of the Flower Moon is a sobering appraisal of America's relationship with Indigenous peoples and yet another artistic zenith for Martin Scorsese and his collaborators.

Strong acting, gorgeous cinematography, and a powerful story keep Killers of the Flower Moon engrossing in spite of its slower pace and extreme length.

'Killers of the Flower Moon' is acclaimed for its powerful performances by Lily Gladstone, Leonardo DiCaprio, and Robert De Niro. The film is lauded for its historical significance and emotional depth. However, criticisms include its lengthy runtime, pacing issues, and missed opportunities to explore the Osage Nation's cultural and historical context more deeply. Despite these drawbacks, the cinematography and production values are generally appreciated.
