I am in agreement with most of what Chris has described. But his commentary about the movie is more about the amazing man and his singular story itself and less about the movie. I enjoyed the movie immensely and yet perhaps I am more focused on the movie experience itself as a drama rather then as a documentary which it is. It's likely I am comparing apples to oranges when I say this, but the more emotively impactful mountain climbing movie experience for me was Touching The Void (2003) the vivid and emotionally riveting re-creation of an historic near mountain climbing tragedy.
