This is a harrowing story of survival in a brutal landscape. The film conveys the sense of isolation and despair and its toll on the human psyche, as well as the will to endure against all odds. At times this was hard to watch, especially as a dog lover, but that's the cruel reality of polar expeditions. Stepping back from the story, this was ultimately all about the willingness to put oneself in a horrible situation for the sake of adventure and nationalism. I'm glad the two men survived and lived long lives.
