Tommy Lee Jones has a wry, dry character -- rich and deep as unwatered open plains of the Americas. He's transferred his particular personality power to the story of The Homesman. He's successfully created a fine work of "auteur cinema" (much as I personally think this form rarely exists).
The Homesman is an emotionally and powerful, idea-rich, almost humorless story -- with an immense amount of humor. It has very tight, economic tale telling with no fat on the bone; in which much is implied, historical accuracy hits its target by nuance, and the story itself is deeply respectful of an intelligent audience.
The Homesman is not "entertainment" in the haha, shoot-'em-up Western sense. It's realism committed to a moral cause -- criticism of the disenfranchised, the homeless, the people who cannot make it no matter how hard they try. It has a brilliant sense of time and place that tells the life stories of dozens of hard-enduring, long-suffering "forgotten men" -- the women no less than the men.
The key heartbreaker is Hilary Swank's character of Miss Mary Bee Cuddy. She's born into a Western frontier world where she and everyone else believes and practices that "No man, having put his hand to the plough, and looking back, is fit for the kingdom of God." Hard workers and decent people. But tragically that is not enough. Why? The Homesman leaves that question deliciously unanswered. Life is not fair. God is not just.
Beautifully The Homesman does -- kind of -- answer life's problems with the value of sheer vitality and gutsiness itself. Thus that key visual motif in the movie that comes from: George Caleb Bingham, "The Jolly Flatboatmen". We must dance the dance of life, however mad.
