This is one of the most outstanding crime, detective series I have watched. I love how there different stories told within the story itself. The cases actually has more depth than usual and actually stirs emotions. Unlike, most crime dramas, Signal didn't revolved around corruption only but more on the story of its characters so very good job on that.

Most of the times I find shows which has vintage feels to it confusing or boring but here I really appreciate how it takes us back to 1989 when I wasn't even born. The cinematography added that vintage feels that it won't be hard to tell which is the past and the present. The OST also complements the overall mood of the show. The song has 90's feel to it which I surprisingly get addicted into.

My mind is still blown on how the story went and I admit although the ending is a bit confusing for me, I really enjoyed the journey of watching each drama. All characters are really interesting and their chemistry on screen is superb. My time is definitely worth it. Thumbs up to the Kingdom screenwriter who wrote such an amazing story. The elements of the story like the time warp, the cases, the slight humor, the emotions, it was risky to be put together because it can end up a disaster but this one stayed consistent from start to finish.

I don't really re-watch heavy dramas and crime thriller because the excitement is no longer there 2nd time around as I know what happened already. But if there's one thing I can assure, the story is really worth it. If you're a crime thriller seeker and loves emotional dramas, this a very good recommendation. Heads up to those who doesn't like vague ending though as this drama has an open-ended finale.
