Lee Dong Wook, wow, he did amazing as the Mountain Spirit Baekdudaegan Lee Yeon, Jo Bo Ah who played Nam Ji Ah, and Ah Eum also did amazingly. Kim Bum who played Lee Rang did really well as brother to Lee Yeon. The fantasy was there but wished it was more. The fighting scenes were not great but good. The costumes were excellent! I loved the storyline which captured my 10 points and of course, it couldn't be done without the main leads and the supporting cast. The music was great! I hope I see more dramas with the two main leads. I believe there was chemistry.
