Favorite dramas so far

Story, acting, direction and musics... All were awesome and touched me  so much. Waiting for the 3rd season to add in my favorite list.

I'm still so impressed with the musics! I'm sure it's composers are intelligent. Most of all, the violin is really ear-catching.

The direction and acting are very good, but the characterization could have been better for some characters.

For me, the best Korean sci-fi I've ever watched. The visual fx is wonderfully great -which I haven't seen much in Kdrama. I also like the direction.

But on the other hand, Hee-joo's characterization is very weak and thus, the romance seems extra and nonsense; And Se-joo's backstory is not focused on as much as it should have been. So the drama is so far from being very good. But the reason why I love it, is that the main genre (sci-fi), its storyline and even the ending is written very well and based on the logic of the drama.
