My opinion about The K2
Despite a scenario filled with countless stupidities, I really loved this drama. One of my favorite to watch

NEGATIVE POINTS
It's hard to believe that a script so poorly written was produced. The way things are turned make the drama not natural at all. The basic idea and events that occur throughout the drama are absolutely simple. The screenwriter seems to be a beginner. Stakes are big but basic, and all things that take place in the story seem to have arisen from a simple idea, without the screenwriter having taken time to let them mature. However, this is the most important thing to do when writing a screenplay.

Some scenes are a bit long, and some moments are too explained, giving the impression that the screenwriter took the spectators for fools. It's a beginner's mistake again

The action scenes are for the most part forced, and some almost unjustified. Obviously, the screenwriter has forced himself to make an action drama

Everything that happens in the last 10 minutes is totally ridiculous. And Choi Sung Won (Lee Jung Jin) deserved something grander, given his character
(This role is purely Lee Jung Jin !)

GOOD POINTS
What really made me love this drama is the character of Choi Yoo Jin (Song Yoon Ah). She's an incredible actress, she acts perfectly the kind, sweet and adorable woman as well as the merciless ultra devilish witch. She's the best actress I've seen so far. I totally feel all of her emotions, especially the despair and loneliness she feels. She's a strong person but very frail at the same time. I really understand her character, that's why I've always been on her side, without doubting her until the end. I never really considered her to be the "bad one". What I also really appreciated was her story with Kim Je Ha (Ji Chang Wook). We feel that she's attracted to him although we don't really know what she feels, it's really a shame. I would have liked this side to be more highlighted. I loved this "romance". One of my favorite parts
I didn't find Jo Sung Ha (Jang Se Joon) extraordinary, but I could feel during all the drama that there remained a bit of love between him and Choi Yoo Jin. So I bet they are both amazing.

I liked the romances, but it's a shame that it's too fast. But that's one of the best things for me in this drama. I really loved when Je Ha observed Anna (YoonA) through the cameras !
