This Drama goes on my Top list of Overall B.E.S.T Dramas of 2012. Everything was phenomenal. I want to start off with the pace of the Drama. The pace was PERFECT. No words can describe how well the pace of the Drama went. Storyline didn't drag, characters didn't hold unnecessary secrets. When something happens everyone knows it and it doesn't get withheld leaving main characters clueless for like 4 episodes or something ridiculous like that. You know, the typical elements that make K-Dramas drag. Storyline is a solid A+. It may be about revenge, a typical in K-Dramas but in a pool of revenge dramas, this one sticks out. I'd even hold this Drama up on the same level as 'Bad Guy', another masterpiece of revenge in my opinion. The cast couldn't be more exceptional. Everyone really delivered in their roles. Every episode is a anticipation and to top it all off the OST is amazing. I rated re-watch value a 5 only because, yeah It's good enough to watch again but when you watch it once, you already know what's coming, what's going to happen and for me at least, It's difficult to re-watch something I already know the outcome of. I do love to re-watch my favorite scenes though!
