So unrealistic! In no way would anything they did happen the way the movie portrayed it.
The fact that they landed on top of a mountain, were able to withstand the subzero temperatures and low oxygen level, then climbing down without any gear, and jump off a cliff without be impaled on the tree was totally ridiculous. Never mind the fact that he had broken ribs.
Then there is the avalanche which would have buried her under tons of snow, and he would have never been able to dig her up with just his hands. They both would have died from exposure, but that would have been a much shorter movie. Lol
