This is about as straightforward of a survival story as you can get, but it is executed very well. Mads Mikkelsen is pretty fantastic, the writing is not expository when it doesn't need to be, and above all it looks beautiful. The cinematography in this is sincerely astounding, Tómas Örn Tómasson makes every single shot interesting, which isn't a particularly easy task in the middle of a tundra.
There's nothing really deeper than surface level here, and it's about 10 minutes too long, but boy was I starved for something to see in the theater and this scratched that itch perfectly. It's just solid filmmaking.
