+1 Cast: I don't think the two leads matched but they were great leads individual-wise. The second male lead I found to be quite boring,  except for his swordsmanship

+1 Videography/Cinematography: was absolutely amazing. Probably one of the only reasons why I kept watching this drama was because it was greatly done. The visuals were amazing.

+1 Music: It didn't catch me at first but wow, towards the end the music really gets to you

+1 Value of Friendship, Peace and Kindness: The female lead did a great job holding a strong character that stood up for her values of friendship and kindness and pursuit of peace. However, it's what got her in trouble and what made me upset at the same time.

+1 Complex Relationships: The main two leads had a complex relationship. I'm not sure if I liked it or not. All I can say is, they both have trust issues. At different points I had feelings of contempt for both of them.

+1 Action: Action was better than most I've seen in dramas. The swordsmanship and fighting kind of got redundant for me because so many fighters kept showing up and some of the same fights kept happening over and over again so I skimmed through those parts knowing that the action was already good. It was the storyline that needed to hurry up.

+1 Clothing Line: I was a bit disappointed in the female leads clothing set but I knew it showcased her value of modesty and simplicity. However, two particular I enjoyed seeing clothes in was the first male lead (King) and the Han Shen.

+1 Tragedy: I enjoy tragic genres in general

-1 Story dragged like most dramas do. I'm glad it wasn't a 50+ drama. Hallelujah Amen!
-1 I felt uneasy about the female lead the second male leads relationship (her senior, not the king). I guess I'm just never comfortable with the idea of a person who walks into another relationship while still in love with another person. On top of that, I personally wanted her to only be in love with one person.
-1 Redundant political schemes as always.
