It's good to see Frank Hamer, a legendary Texas Ranger, get his historical due. I never did like the way he was portrayed in the Arthur Penn film about Bonnie and Clyde. And this film de-romanticizes them, portraying them like the murdering scum they were. Good performances, with Costner and Harrelson possessing excellent chemistry. A+. There is an excellent biography of Hamer by John Boessenecker published in 2016 that I highly recommend.
