This drama promised action, and action it had, from the get go. The action choreography was just out of this world, *chef's kiss*. The acting was also quite good, with Woo Do Hwan and Lee Sang Yi being the best action pair one could ask for. I loved how the women were also quite well equipped to handle their own, and not mere sidekicks. I just wished Kim Sae Ron didn't have this abrupt exit though.
Let me just take a moment here to shower praises on the lead actors' bodies. They have WORKED OUT FOR IT, and it shows... Every muscle, every sinew in their bodies are so fucking well sculpted, it was a feast for the eyes ? I was particularly impressed by their running shots - most of them were taken in a single shot, and they sprinted the whole time. Just goes on to show how FIT AND ATHLETIC the actors were for this role. It was a short watch, but packed with a lot of suspense. Till the last half of the last episode, I was unsure if it will get over in one season or if there will be a 2nd season chasing the villain. Also Park Sung Woong as the villain was a delight to watch. Cold, killer eyes and that maniacal smile was enough to protray all the malice that his character demanded. This was quite the refreshing watch after a series of average to bad Cdramas binge sessions. Overall, would totally recommend it for the action scenes and the easy camaraderie between the two lead men.
