Summary: This is a must watch, every episode was like it was straight from a cinema. This show is hyped and rightfully so, I have yet to see another crime/investigation drama like this one. I was on the edge of my seat the whole time and surprisingly the writers, producers, and actors kept that suspense throughout the whole show. +/- Plot: The plot went from thick and thin, and I mean that in a good way. They didn't leave you too confused from the get go, but they would subtly unfold different factors so that you could come up with your own theories not only on the investigations but the actual backstory too. I loved how each of the crimes were told in a different way, some cases from the start you knew who the culprit was, but others left you guessing. But it wasn't the investigations that left me satisfied with this drama's storyline and production, but the actual backstory that linked all the characters together. As we slowly started uncovering the corruption I couldn't even handle! I was actually bawling my eyes out from anger at one point and I couldn't even stop it. I loved how they producers perfectly weaved the present with the past, at no point was ever confused. +/- Acting/Cast: All of the actors really did an amazing job at telling their characters' stories. I was deeply moved by all of them. I have to say though that Jo Jin Woong really stole the show. What made me love his character all the more was how dedicated he was as a detective, friend, etc. He was so upright and true to morals, no matter who was persuading him to do the wrong thing, and that's what I admired so much about him. He really was extraordinarily charming. Lee Je Hoon portrayed his character fairly well too, I really felt the anguish with him during the times we found out the wrongs committed against him and his family. I will say that in the first episode or two I was a little annoyed with him, not sure if it was his uppity character or a little exaggeration on his part, but it took me a couple episodes to warm up to him. But once the fondness developed, I began to really enjoy his acting and portrayal of his character. Kim Hye Soo's character was a little off putting to me for some reason. I think it was how much they contrasted her throughout the show, I was just a little unsure of her throughout the whole thing. In the present she's a complete badass, but then that's contrasted with her character of the past with the 'flashbacks'. And we see her in a completely different light, timid, innocent, and kind of dumb. I mean, I really liked her present portrayal which is probably why I was a little disappointed in how much her character differed. I guess it's just that I wanted her to be the strong woman character that's so rarely seen in dramas, but in the end I guess everyone has a weakness. +/- Music: I loved how they chose to remake some old 80's songs for their soundtrack, I thought it was a really nice addition and touch to the whole show. It exposed me to a lot of songs that I would have never otherwise known about. They also put in the suspense tracks at the right points, got my blood pressure up and left my palms sweating even! Rewatch Value: I would definitely rewatch this drama, the storyline hands down is amazing and the cast worked really well together. I think it would still have the same suspense factor that it had the first time I watched it.
