What to say about Signal besides the fact that the drama is perfect? 2016 and TvN started with the right foot, Signal is amazing, well written, acted, the developments even though some of them would break my heart sometimes, made complete sense. The mystery would leave me at the edge of my seat every time, but the feeling of wanting more was always there when they completed a case. I stopped watching on episode 6 and started again when the drama was complete, I cried my eyes out, but those were the best 10 hours of my life. The 3 leads made my heart break so many times with how good they were, their desire for justice and the truth made me respect the characters so much more, those are the kind of people I would want working in law enforcement. If Jo Jin Woong's acting is always like this, he has a new fan, Lee Jae Han is unforgettable. A special remark on Kang Cha Ni (Park Sun Woo), I already loved the actor for his work in "Can you hear my heart?", but here he proved just how good he is, since the first time he appeared I cheered for him, but OMG, I cried so much for him, for his family, angry tears for those cops, those students, I never thought I would say this, but my heart actually hurt for everything that happened, he's one of those young actors that I have to keep an eye on. I just didn't put 10 on the rewatch value, because I hardly go back to watch a 16 episodes drama, maybe one hour and a half movie, but not a drama, but that's me. Overall, Signal is perfect and a must watch kind of drama.
