So much happens in six episodes, and yet everything so well written and so well paced, it's amazing to watch it unfold. Kim Woo Bin does an excellent job driving this drama from start to finish. The plot is very linear, but sophisticated. You have to pay attention to every detail, because this drama won't repeat itself twice. Our characters are full of life, and love, and the actors portray them very well. Our three main characters, 5-8, the dashing deliveryman, and the 'hope' 'legend' for the refugees is the man leading us to equality, and freedom. Our second character, Sawol, the future deliveryman wants to follow 5-8's footsteps, and we come to know he is a mutant in later episodes. Because of Sawol's mutant blood, our antagonist, Ryu Seok, wants him to cure his own illness. Then we have our Major, Seol Ah, who will do whatever it takes to protect her family, and the citizens of Korean.

I highly recommend this drama. A very good binge that won't leave you craving for more, and with a satisfied ending. If you are a Kim Woo Bin fan, you are in for a treat. Not only does he look healthy, and dashing, he portrays a superhero characterized very well by his amazing acting.
