I, like some people watched The Tunnel first and loved that one. When I saw that Signal had almost the same premise as The Tunnel I decided to watch.

For some odd reason I only made it to the first episode. The female lead messed it up for me. Her demeanor, and facial expressions made this less enjoyable to watch.

Someone stated that I should definitely watch so I followed their suggestion. To my dismay I really didn't like this too much. The male character who was in the past played his parts to where I clouded up a bit in some scenes.

To me the two male cops connected even though they never meet. Other cast members seemed to be disconnected from each other.

The cases that they dealt with was interesting but in my opinion it lacked intensity and depth. Especially the last episode. It caused me to be so disappointed with the days I spent watching this. Some of the dramas that I've seen know how to wrap it up in the last episode and a lot of dramas that I've seen don't know how to wrap it up and this was one of them.

The pace in every episode was extremely slow too.

I wanted to like this but unfortunately I'm one of the few who didn't care for this too much.
