I found this movie very realistic and relatable especially with the pandemic we are living in now. The loss of family, depression, suicidal thoughts, complete isolation driving one crazy, shortage of food and value of each drop of water, the need for a human connection and the need to survive. The part where Yoo Ah In just tried to drink water spilled on the table after realising that water has run out was an intense moment. There was no unnecessary action and I was glad to see that the characters were not trained fighters like many movies show. Despite it all, the action and horror was impressively portrayed in the movie. Many might expect romance too, but since the movie focused on realism, we know that romance is the last thing on your mind during a virus outbreak that you need to survive. It was just two people trying to survive...absolutely wonderful movie! Would recommend
