Soo here I am once again to write a review about a great production that has amazing cast, a lot of work put in the scenario and the plot and yet again I feel somewhat angry at the end for 2 reasons. Let me back up from the start - the concept with the plane crash and discovery of the twisted truth with the help of a few NIS agents was great. Not knowing who to trust, who not to... it was very thoughtful. The cast did their job perfectly from sad scenes to sexy ones to the action ones. Everyone really. The plot twist in the last few episodes was something that I really enjoyed. Unfortunately what was not enough for me to give the drama 9 or 10 starts was mostly this - you cannot tell you have one of the most expensive productions ( 25 billion Korean won from what I've read) and have shaky cameras on nearly every action scene. I swear it was like the people behind the cameras were not shooting with professional cameras but with their phones with stabilization turned off. It really messed up with me and I couldn't enjoy those well-thought of fight scenes due to the fact it was all moving around like there's ongoing earthquake. The other, smaller though, reason I was disappointed is I am finishing this drama in 2024 and it is clear that they won't have season 2 so the ending really bugs me. If they do another season after all I will probably update my rating with some minor increase but still I cannot let go of whoever thought this camera works was good enough for the amount of money they were given. And I really have to ask the question, does Geon sells himself too? Cause I understand the concept about infiltrating and revenging but to be part of the organization and that deep into cover, he must have had to kill a number of innocent people too, so is he no longer innocent and goodie? I am really confused once again about the end
