This was terrifying, I think because of its sheer realism. Nobody expects they're going to die when they decide to get out of their car and trek to the cabin in the dead of night. But it sneaks up on you through a series of small mis-steps and you could pay with your life for those little mistakes.

Should've stayed with the car. Should've called for help. Once he got out, he should've stayed on the road instead of cutting through the woods. Should've ditched the skis once they broke. Should've exerted himself less.

Lots of little should-haves like those are what can kill someone who's not prepared for and experienced with harsh conditions.
