I was pondering whether to write a review to this wonderful drama or not. But in the end I don't think I could find closure if I don't write something about it. There is this thing with a 10 point rating. Some give it very easily, some almost never give 10 points. As for me, it's like this: If a drama is successfully absorbing me into its universe and everything just seems to be perfect to me, then it reached a point where it's worth receiving my whole dedication. It doesn't matter if others say, there are flaws in it, whether it's true or not. I just don't see them anymore as I am part of that new world where there are no 'story-faults' and such things. Signal was successful in every matter. Story. First episode and it just pushes you right in the middle of the event. You get immediately drawn to the characters, the suspense and the story. You don't have time to take a deep breath, instead you completely hold it. And when you think it's over and you can take some minutes to rest, the next incident is already starting and you just get sucked in again. If you're lucky, you get some minutes to reminisce about and take in what just happened. But as the story continues, the suspense intensifies and breaks loose in a shocking finale. Characters. They like to play with your emotions. Ups and downs, but most of all excitement and anxiousness. Plenty of. The acting was on point, it captivates you. There is this female cop you're dealing with. And there's the present version and a past version of her. They are completely different as the older version has matured and became stronger. You just see the growth. And there's this guy. You see him and you want to help him. You see his conviction and his struggle. You just want to be by his side, so he won't be the lonely hunter in a forest full of wolves. And then there's this boy. He's so full of himself and full of hate for others and the world. But he gets a chance and a view from another angle. And he takes it. And don't forget this villian. You don't know about him right away but you soon grow to hate him like no other. Extremely. Wholeheartedly. Music. Every minute, every scene, every moment. It just fits. It just gives you this special feeling about the story and its meaning. And then there's this nostalgic feeling to it. You can't even discribe it. It just takes you back in time and like you're reminiscing about your own past, it carries this wistful desire to actually go back, live again and maybe change something. Background. To get to know that many cases are real-time cases makes the drama even heavier and impacting. Sometimes you think writers create scary non-realistic monsters. But truth be told, our world, our reality creates the most fearsome monsters you just wouldn't believe them to exist among us. Message. Whether there is one or not. Everyone has to decide that for themselves. But the drama depicts some really interesting and worth thinking about questions. Most of all: What would you do if you could change the past? Deserved 10 points.
