This movie has a great performance by Jeff Bridges, but I can't help think about how much better The Wrestler was as a complete movie. Both involve formerly famous men physically and emotionally falling apart as they get older. That said, I would recommend it to anyone who tends to like Oscar Bait type dramas with great acting by memorable male characters (e.g. Milk, Capote, Ray, A Beautiful Mind, etc). As long as you don't mind the awful title...
It's a feel-good story, but Clint Eastwood doesn't let it get sappy or silly. It works, and the acting is solid. Most of all, it's a great reminder of a modern hero, Nelson Mandela. My only complaints are that it gets a bit tedious and the music is pretty bad.
