This is definitely one of the best movies of 2017. The story centers around the mystery of a dead native American girl/woman (18 years old). It is not an action thriller. It is a "deliberately paced" (read slow) mystery, but I was never bored. If you liked "The Killing" or "Broadchurch" you will probably like this too. The pace allowed proper character development. With the exception of the "bad guy" revealed at the end, all the characters are nuanced and interesting. Ultimately, I cared about what happened to each of them. The ending is satisfying, but not happy.
Renner gives a wonderfully understated and brilliant performance as the protagonist. His characters is broken but pushes past his own pain to help the people he cares about. He is a gun carrying hunter, but lacks any male bravado you would expect from Hollywood. He cries, he hugs, he is gentle with others but never once comes across as a wimp. He is rugged and sincere, a High Noon Marshall Kane type.
Olsen also turns in a great performance, but her characters is mostly expositional. She plays an in-over-her-head FBI agent, who is also free of typical Hollywood tropes. She is assertive and confident, but also smart enough to ask for help when she needs it and to apologizes when she is wrong. She is no wilting flower, but also not the caustic shrew we would typically get for a woman FBI agent. We learn about the reservation and protagonist through her eyes. We see the brokenness and nobility without any sanctimony, guilt or lectures.
Graham Greene play the same character in which he is usually cast. But, he continues to play the Reservation chief of polices exceptionally well. He is disappointed when he meets Olsen's character, the young lone agent sent to investigate, but fails to treat her with contempt. He expresses his sadness and frustration, at the lack of help, with the gusto of a man who accepted his lot in life long ago. But because our young agent clearly cares about the victim and justice, he attempts to gently mentor her while still respecting her authority.
