This is a really annoying movie. This review contains spoilers.
Firstly, it's a fake true story. The actual true story it is based on was just one man burried in a car in the snow who survived. But this story ads a pregnant woman that gives birth saves her and kills the husband. So in other words, it's fiction.
A lot of the scenes are too dark on screen to see anything. The main character woman is very annoying. There is no opening scene to set the story. They just wake up burried in the snow. At one point she gets a call through to her father but repeatedly cries daddy rather than giving him information about their location or predicament. At the end when she's walking she goes off the road into the snow, not following any path, which is just so dumb. Plus what woman carries their new born baby in a carry bag? Especially if it needs to be kept warm. She gives birth and doesn't breast feed the baby, nor put it on her skin to warm it up. There is no back story showing anyone looking for the missing couple. There was no drama when the husband died. I actually wished the husband survived and the wife died instead as she was very annoying and he was the smarter one.
At one point it shows a sign that something is only 1 km away. The irony, that if they had only driven 1 km more before pulling over they would probably be safe.
