A superb movie if you love good acting. Jeff Bridges and Hailee Steinfeld work to make a believable picture of the book. Frankly, this is much more enjoyable than the John Wayne original (this coming from a John Wayne fan)... and left me cheering for a bygone anti-hero. Can a scoundrel become a real life hero?... Even if you don't want to believe, be prepared to anyway, if you go to see this.
I see that many reviewers were focused on the cut-off finger thing. Too bad... it was short, effectively shot and then on to the rest of the story. I think what many reviewers failed to see is this... that innocence and a sense of morality need not be compromised by violent situations or people. Mattie is forthright, capable and tenacious. But even in the end, her allowance for good, even in the worst of men, plays itself out in the end. If one is seeking a role model, take a look at any of the main characters in this story, set aside your preconceptions (as well as your view of the finger thing) and find what Mattie found. You'll enjoy this story a whole lot more.
