I'm only on the 2nd episode but I'm enjoying it so far
Like other's have mentioned, the pacing is good and the humor mixed in with the drama is excellent. I especially like their take on certain things, like this one scene where the bad guy is secretly tailing the good guy and he ends up getting rid of him, but then we find out it was because the good guy was really lost and didn't do it on purpose!
Also, while they don't look that much alike, does anyone else thing Zhao Li Ying's character with the ancient dress looks a bit like Jang Nara in My Bratty Princess?
Edit: I'm nearing the end of the first set and the script writer is really bugging me. For example, Su Huan Er seems to be getting more stupid by the episode She was so smart and feisty before so what happened? It annoys me the writer just changed her personality so they could fit the plot.
Also, I notice either the editing the directing is a bit sloppy towards the end. There were several scenes where they all of a sudden go somewhere else and it was only explained later what happened. Not sure if they were doing it for effect or what.
Overall it's not bad, but those last few episodes really hurt the overall story a bit. So hopefully the next set will be more consistent throughout.
