This is a great fantasy thriller drama with a nice romantic storyline. The action scenes are fantastic and, for the most part, acting was done well. There could have been better chemistry between the leading couple but, overall, it was not too bad. The brothers Lee Yeon and Lee Rang’s story and interactions were the best part of this drama. Both actors did great bringing their characters to life. The supporting cast provided lots of funny moments to smooth the thriller moments in the drama and their storylines were interesting and engaging. The most baffled moment is Lee Rang’s unnecessary demise. In an effort to create a dramatic flair, the writer failed to take into consideration that Lee Yeon valued his brother’s life more than his own. It’s paradoxical to have to sacrifice a life for a life that has done the ultimate sacrifice to save his beloved. Although this drama brings about the theme of self sacrifice for a loved one, it is also a tale of obsession. It is disappointing that once one of the main characters reaches great character development and finds the true value of family, his life is seeing as less important and okay to be sacrificed to satisfy an underworld god’s greed and Nam Ji-A’s obsession. Now, the ending might seem confusing to some, but it is a very welcomed twist to the finale. The drama is entertaining, enjoy it!
