A few more thoughts since seeing it and I've been able to discuss and process the film a bit more with my wife:
The highest compliment I could give to Scorsese is how confident and in control he is. Obviously he's a master filmmaker, but the restraint he showed was stunning. How do you make a $200mm dollar film look like a documentary? This is how. For a man behind some of the most iconic cinematography and images in the last half century, he let the camera hide throughout most of the scenes. Static shots. Medium and close up shots of the actors. Limited tracking. He made sure the audience was forced to witness everything in this world. It made the few "big" shots in the film that more powerful when they appeared.
The violence was so matter of fact and casual it underscored how little the loss of life to the Osage members mattered. It was just something that needed to be done, as mundane as most of the "jobs" the whites pretended to do while scheming ways to steal from the wealthy tribe members.
I'm not going to waste anyone's time with the performances of the actors, but that was a master class through and through. And Jason Isbell...save some talent for the rest of humanity, dude.
Recapping the post trial events via showing a live radio broadcast dramatizing the event. Fantastic. A million times better than the standard onscreen text tying things up, but also a sly commentary about how crimes, murder and injustice has been both entertainment and lucrative since the ability to recreate and broadcast it has existed.
I'm sure we'll watch it again soon at home. Bravo, Marty. I don't want to be greedy because if that's the last film you ever make then job well done. I think he's only got two more big projects he's been trying to make for many years and those are both biopics: Sinatra and Teddy Roosevelt (with Leo as TR). Stay healthy.
