I'm writing this right after watching the last episode... I've been repeating the last scene for more than an hour now nonstop... Let me just say that I'm deeply in love with this drama, I'm so in love and attached to the point my heart hurts now that it's finished... Story: The story from the start to the end never ever failed me, the more you watch the more you WANT MORE !! It's the kind of story that touches your heart continuously and keeps your mind busy all the time. This drama is really special and unique, it so different from other dramas that I've watched before. My favorite theme is "revenge" and I have watched so many revenge dramas but they are absolutely nothing like this one. I would gladly explain why I loved the story so much but that would mean mentioning spoilers so I'll just say this "when you watch you'll understand why this drama is one of the best". Acting: UHM TAE WOONG no matter what I say about him it won't do this guy any JUSTICE !! I loved his character the most he has done an amazing job and gave me an unforgettable performance. What makes this drama even more special is that EVERYONE did a WONDERFUL job and I do mean it when I say EVERYONE (guest characters, supportive characters and main characters they all did great). For once it's not only the main characters that shined others did shine too, each character managed to grab my attention not just the main ones. The characters in this drama are the most complex characters I have ever seen, you don't know who to hate and who to sympathize with, who is the victim and who is the devil. Music: I loved the OST of this drama, it went so well with the story. The music contributed so much in the story it made it more real and intense. I loved 2 songs the 1st one is "Don't Love Me" (Saranghi Marayo) Sang by Uhm Tae Woong and the 2nd one I don't know what is the name of it so here is the link to it: (http://www.youtube.com/watch?v=7RJa1zpHSPQ&feature=relmfu). Rewatch Value: I think I would watch it again I'm even thinking of watching the Japanese remake of it (and I'm no a person who would watch remakes but in this case I will). However, since TD is a mystery drama it might not be a rewatchable drama to some of you (cus the mystery part will be gone). OVERALL: The Devil in one word? a MASTERPIECE. To everyone who hasn't seen this drama yet, what are you waiting for?? start watching it now... FYI this drama is the 1st K drama that got adopted into J drama (it was always the other way around Koreans adopting Japanese mangas/animes/dramas) but in this case no and that says a lot doesn't it?
