What are you impressions after having watched the whole drama?
I enjoyed it, the story was really interesting, the characters as well, the music was great. Not to mention the costumes and all those things that make us love historical dramas ;) It's a pity though that some of the subplots were not developed...they could have been very interesting, for example Seol's story...But it would require 40 or 50 episodes to develop all the plots, so maybe it's a good thing they kept it short.
One more thing...Is it just me or did you also dislike the adult version of YeonWoo/Wol? I don't mean the character, although it was really underdeveloped which made her not credible, but the actress!! Her horrible contact lenses which made her eyes look so unnatural and stupid...Her way of speaking - poor attempt at seguk speech...She didn't look convincing as a woman in love or as a person who has been hurt...All the time she resembled a sheep who was doing what she was told, without any emotion. There she was, acting like a shaman without asking about anything...then coming to meet the king without the slightlest change in her expression...then she found out all that had happened to her and still nothing, her face looked just the same...the king recognised her and made her sit behind a screen in his chamber...well, whatever, she accepted without a word and just kept looking and speaking the same way...What was that supposed to be? Her acting made her character look totally unconvincing and even dumb at times...The child actress was 1000 times better and more professional!
