Most of the times, I have a hard time watching Korean crime dramas. Though they are exciting to watch, sometimes there are just too many names to remember (hard to remember foreign names vs english ones).

I am currently watching the Queen's Umbrella and saw someone comment in his review how much he liked Kim Hye Soo in Signal. I loved her in Juvenile Justice so I decided to watch Signal and see her in a different role.

After finishing this series in record time, I agree with loving Kim Hye Soo. Not only is she a great actress, she totally suits the role of a tough detective. I also loved Jo Jin Woong. His acting is so natural and he is so in character as Detective Lee Jae Han. I looked around for his other dramas but sad to say that he doesn't have any current ones.

The storyline is also well written. It captures the viewers interest and there are some heart pounding moments when you wonder if this or that is about to happen.

While the radio transmissions give you Frequency vibes, it is still different in certain ways. Definitely a must watch
