The Koreans have proven their ability to produce world class VFX standards and without a doubt they've done it again in this movie, but what surprises even more is how the moon expedition story was written in such a direct yet highly emotional way, the script is almost perfect and acting performance is just unbelievable. The action sequences were designed to move the audience's heart and the director succeeded it by keeping the tension at maximum level throughout the whole movie tragically. My tears keep rolling in my eyes for 2 hours straight while I'm gripping the edge of my seats, as it propels to become one of the best movies I've ever watched in theaters.
