This drama is awesome!!! If you like psychologically disturbing, deeply emotional, life questioning dramas, then you will like this. I don't know if I am qualified to write a review for something this emotionally provoking. The synopsis for this drama doesn't even begin to tell the story. It is dark, but somehow gives hope. The story is very detailed and all the characters are intricately combined. The imagery as well as the references to Dante's inferno and Rodin's Gateway to Hell etc. trigger so many emotions and elicit so many thoughts. The use of the tarot cards throughout gives answers and brings questions. I was blown away by the way each character’s story is told. The cinematography was so well done. There were so many scenes that I thought were perfectly portrayed. There are very few times in this drama when I knew what was going to happen next. I watched this ***with my sister, finally someone to watch drama with*** in a few days because it was hard to stop due to the perfect pacing of the drama. I almost felt desperate to know what was going to happen next. The ending is one of the best that I have ever seen. I would give this drama a 10 for the ending alone. This isn't a romance and there is no fairy tale. If that is what you want to watch, then this is not the drama you are looking for. The acting is beyond great. Uhm Tae Woong plays Kang Oh Soo who is the detective of this drama. I won't try to tell his story, because it is too complex. I have liked Tae Woong as an actor for a long time, but his portrayal of Kang Oh Soo’s good, bad, and ugly emotions is perfect. It is hard not to find this character pitiful and lovable. Joo Ji Hoon plays Oh Seung Ha. This character is so multifaceted. He is cold but just by using Ji Hoon’s expressions, I knew there was more to him. There is no way that I could not be sympathetic to his character. I have seen Ji Hoon in Goong and Antique Bakery. I liked him in both, but I really had no idea that he could pull something like this off. It makes me want to watch Five Fingers next. I love Shin Min Ah. She is one of my favorite actresses. I don’t know why she isn't in more dramas. I’m really enjoying her in Arang and the Magistrate also which is airing right now. I hope she does many, many more. Her portrayal of Seo Ha In is so good. She IS the light in this drama. There are so many more characters that make this drama worth watching. Usually I get annoyed with secondary stories and lots of secondary characters, but for this drama every character had his/her place and the actors did a great job of bringing those characters to life. Honestly, I couldn't tell you what music was played in this drama. I can say though that it wasn't annoying like some music in a melodrama can be. I will rewatch this at some point. I recommend this to anyone who likes revenge and psychological dramas.
