We watched The Highwaymen and enjoyed it. Then I read the mainstream reviews. The professional reviewers seem preoccupied with how it compares to Bonnie and Clyde (1967), the enduring classic starring Warren Beatty and Faye Dunaway by Arthur Penn.
The Highwaymen is a different movie for a different time, as is Gun Crazy (1950), which also dramatizes the real-life crime spree of Bonnie Parker and Clyde Barrow. It's different because it tells the story from the point-of-view of law enforcement, but also because of what it says about America.
This film makes clear that in the 1930s people were desperate for work and desperate to put food on the table. Since hard work and playing by the rules wasn't working, the people loved the idea of breaking all the rules and taking whatever they needed and wanted. Bonnie and Clyde became their heroes.
This film makes equally clear that Bonnie and Clyde robbed and killed poor people as well as rich people. They had to be stopped, and conventional law enforcement couldn't do the job. So the governor of Texas, Ma Ferguson (Kathy Bates), hired a couple of former Texas Rangers to work without official authorization.
Thus, this movie is about outlaws chasing outlaws at a time when the people had lost faith in the law. There is no romance about the real-life law men played by Woody Harrelson and Kevin Kostner. They're smart and they're tough, but they are thugs hired by the state to kill. They know that's what they are. That's made clear in a speech by Harrelson late in the film.
There are neither heroes nor anti-heroes in this film. There is instead a description of America falling apart as it did in the 1930s. There is also a reminder that, bad as income inequality is today, we have seen nothing approaching the Great Depression in my lifetime.
