DRAMA REVIEW: Signal Was urged to watch this drama after seeing this as recommendation on almost every comment section of dramas I've watched. The Story: 10 What I know before watching the drama is that the leads are detectives/police. So when I started watching the drama, I had no idea about the walkie talkie connection. It is a challenge to create a drama dealing with the time paradox as one of its main theme (I haven’t watched Nine yet and I am disappointed with Marry Him If You Dare so I am basing my comments on the time traveling theme on the good animes I’ve watched). Park Hae-young of 2015 is the profiler who initially connected with Detective Lee Jae-han of 2000 while solving a case related to his childhood. He crossed paths with Detective Cha Soo-hyun and her team and after solving one case, they were brought together to form a team that solves cold cases. I love romantic comedies and all, but I have a separate appetite for dramas of this kind. I’m gripped and intrigued by the first hour of the drama and I was wondering whether how they will pull off a drama while playing the past and the future. I have to commend the writer for stitching every detail of the plot to create this wonderful drama. For this to work, the rules of the connection between the past and the future must be logically established to be convincing and that there is a way to resolve the convoluted conflicts that our characters encountered. Having a different future for every changed past event is convincing enough for me though it sometimes break my heart to see that in some cases, the change was for the worst and not the better. The Cast: 9.5 Lee Je-hoon did well with his role as a profiler who hates police officers. He became jarred because of the things that happened to him in the past but had remained innocent and hopeful that cold cases can be solved. Kim Hye-soo surely fits the role of the tough team lead for the cold case department but is much the same effective being the inexperienced maknae when she was starting. Cho Jin-woong is such an awesome guy for his character. I love his sincerity towards the cases he handles, his firmness in upholding what he believes in, and his awkwardness when dealing with first love and the like. Even the villains here are so effective that I want to kick and punch them while watching. Music: 8 I have nothing against the music, it’s just that I am really not much of a fan for the music used in this kind of dramas. Rewatch Value: I can rewatch this all the time until they give me a Season 2!
