As said in my headline, the only positive thing about "the K2" is the main actor Chi Jang Wook who almost carried the show. Unfortunately, him being good alone is not enough.
I dropped at the episode 6, I even forced myself to continue until the episode 6 because I was hopping it would be better but I was wrong.

Let me start with my biggest disappointment : the romance. The romance in the drama was in my opinion the biggest negative point, it was too cringy, embarassing, boring and childish to a point where I just had to stop because it was ridiculous, honestly.
Secondly, the female lead Im Joon Ah was not good enough, I am sorry, in my point of view, her acting skill is lacking, it is not bad but when you play alongside Ji Chang Wook, you should have a decent level because if it is not the case, your poor skill will be seen from far away, sorry.
Thirdly, the story was lowkey lacking as well, I felt there were too many plot and it was kind of like a mess, it almost was good but it was not (the political stuff had potential to be entertaining but it quickly became boring and also because of the romance who ruined it as I previoulsy stated).

Overall, I feel sorry for Ji Chang Wook, man I am sorry for you. You deserved better.
