You have to watch this movie at least once in a lifetime

I don't even know how to describe how this movie added so much joy and also pressure (in a positive way) while I watch it. I enjoy it because I like all about space and the CGI is so realistic, but the plot is made me feel like I'm in a rollercoaster ride. I want to save Sunwoo so bad. The acting of the actors are really amazing, Doh Kyungsoo as the main character shows every emotions greatly. And he's handsome as hell. He's perfect for film industry. I hope korean film can be more popular with the quality it has like what The Moon did.
