This is the perfect film to watch when you want something that will not only entertain you, but also enrich you. There are so many great docs out there today and this one stands up with the best of them. The subjects are fascinating and you see them in ways that you never have before, which is a true feat, given how public they are. You will also get completely immersed in the highs that you'll feel from the action of the sport and the juxtaposition of the emotion that is palpable when each one of these men faces a hugely difficult moment in their lives. It's not jut a film about boxing, but it is a film that you can enjoy whether you are a boxing fan or if you are not. I watched on Netflix, but you can find it many places online.
