It would have benefited from generous editing At 51 episodes this series was a sweeping, colourful, exciting epic full of love and hate, jealousy, rivalry and brutality. The major villain is a grand Councillor Yeonchol, whom I can't seem to find in the credits. He is/was a powerful general whom eventually deposed four emperors, his final target being Ta-whan (Ji Chang Wook) a weak and powerless young man who was content to be a puppet king in exchange for his life. Whilst in a neighbouring country he meets Seung-nyang - a tribute woman who pretends to be a man. Both he and King Wang-yoo fall in love with her not knowing her true gender.
Koreans love this device - it's about as woke as they get, thank goodness. Both men fight for her attentions.
Eventually Ta Whan is made Emperor and Seung-nyang becomes his Concubine. It takes many trials and tribulations before she softens towards him and she helps him to take control of his kingdom and the throne.
There are things that defy belief - the episode where Yang gives birth and loses her baby in the mountains only for Tanashee to find it is too much of a stretch to accept. Also the fact that Ta-Whan never mentioned that he never had sex with her. There are also far too many battle scenes.
I also find the familiar villain faces a bit too irritating in their ubiquity. Their unconquerable villain scenes just annoy rather than entertain.
The acting was good, especially from the two leads. This was the first time I encountered Ji Chang Wook and I have adored him ever since. He has the most expressive face, and those eyes, I have never seen such a joyous light in anyone's eyes before. I could have stopped at episode fifty. I don't understand how Golta could have swopped heads in the last episode. It spoiled the whole series.
