This drama is so so FANTASTIC(baby~) that I can't express it in words.I have lived every scene of the drama,this is by far one of my favourite drama ever. The story was so well written,it is something that is different from your usual South Korean historical drama.I liked the fact that it included "magic" beliefs since my country is one of those countries that in the past and even now still believes in the power of white/black magic. The acting was great but not outstanding I liked the childrens' acting more,they weren't as emotionless as the olders...also I discovered that I'm in love with Yeo Jin Goo(Jin Goo-sshi just call me Haeri-nuna,ok? :)) ).As for the grown-ups version I can say that I really hated Han Ga In's acting,you may say she is a great actress but to me she is the worse why?I didn't feel any emotion in her acting,her facial expression seemed to be static thru all the drama,it barely changed.It is the first drama I watch with Han Ga In as lead role and since I heard so many people praising her I was expecting something outstanding but she didn't meet my standards.As for Kim Soo Hyun and Jung Il Woo,hell guys,why are you so hot?:((I love them,when I was watching the drama I couldn't decide on which ones side I am.It was a difficult decision(kekek~).Also Kim Min Seo portraited really well the craziness in her character...Iloved her acting. The music really made it for me I loved and I still listen from time to time to it,especially Lyn's Back in Time OST.It isn't a surprise that it charted in korea for a long time and even got the chance to be 1st on charts.It really is a good song.
