An element forgotten later in the movie
Tarantino apparently made the cast watch Carpenter's The Thing before production. In the film the isolationism feeds the paranoia and itself becomes almost a character and makes the film brilliant.
With all the amazing and beautiful wide shots in the first quarter of the film you get the sense of isolation but pretty much the entire rest of the film takes place inside the cabin which quickly loses the sense that the cabin is weathering a brutal blizzard and the tension inside escalates and it just feels like a set in a sound stage.
I personally think Tarantino missed an opportunity here to make the impending blizzard add more to the story and the tension between the characters.
Loved the movie though.
Call it...
