Honestly I fell for the "based on true events" at the start and thought that was about the actual story in the movie so I thought it would be interesting but from the first scene we were getting tense with the inaccuracies. First we have lived in the Arctic circle in Sweden so we know about thick snow! You can see so much light at the top of the windows that they could have easily broken through. If they really were in deep, unmovable snow, the 2 of them and lighting candles would have made them run out of enough oxygen for them to breathe properly in 24 days. In the depth of winter (esp as a tourist) you can only stick to main roads and they are plowed daily (even where we lived with 3 houses for 30mins) so they would have heard that plow everyday and been truly buried within a few days. They even see car lights really clearly through the snow when 1 drives past! Seriously they could have easily got out as the snow couldn't have been a few cm deep due to the light penetrating. The amount of candles they have could have helped melt it since they started to do that DAYS later anyway. Matt also uses the smallest pick to try and break the ice when he said at the start of the movie they had a tool kit for safety (its standard in these Countries) so he could have used something bigger or used the car headrest bars, he is also shown always picking at the ice at bottom of the window, Seriously!? You'd obviously do it at the top to dig yourself out. When she had the baby everyone knows (and clearly she did too as she does it in the end) the placenta is full of nutrients and people eat it anyway let alone when starving and trapped so basically Matt would rather die than eat the placenta? OK.
She finally gets through to her dad and she doesn't even know where they are and panic cries. In situations like this adrenaline takes over and you would be clear and definitely have learnt your position!
Honestly I could go on on and was so happy this wasn't a true story as dam i was starting to feel they deserved it haha. The acting wasn't bad but dam what awful writing how could they not see all these OBVIOUS mistakes! Its embarrassing
