This drama is one of my most favourite ones but it's not for everyone. I can understand that some people might not like it because it's not a typical k-drama, however, it's totally worth of your time.

The story is very well written and the plot is very interesting. It had little bit of evrything but it is mainly crime and mystery but as a fan of crime series I really liked the story . The whole story kept me more and more curious as all the secrets were step by step revealed. After the end of each episode I wanted to know so badly what will happen next.

What also is amazing about this drama is the acting. The cast did such a great job in portraiting their characters and their emotions, especialy Lee Je Hoon. The cinematography was also well done and I could feel all their emotions through the screen. I'm sure that I'll watch Signal again in the future and I'll enjoy it as much as I enjoyed it when I watched it for the first time.

If you like crime and mystery you should for sure watch it right now.
