Connection

The storyline and directing was excellent. This drama captures end to end thriller and has surprising elements until the very end. It starts off with a good speed - gets you addicted to the series! I couldn't stop watching it, everything about this drama was just about great.

The casting was excellent too. Every role is assigned to proper actor/actresses. Everyone nailed their part, especially the main lead, Ji Sung. The addicted detective role was superbly fulfilled by Ji Sung.

This drama is filled with twists and turns, betrayals and backstabbing. It was a great watch, and it certainly deserves more rating than it has here now. 10/10 personal rating and 100% recommended.

The first episode wasn't good enough and if someone would've stopped after watching it then I wouldn't blame them.

However, once the second episode starts and things start to be interesting in the funeral, it is very hard to stop before this show ends.

Korean shows have such a unique touch of making a normal detective-crime series turns out to be something memorable by having an aspect in the story that adds value to it (In our case here it is the addicted detective).

Once again a great Korean drama that blends mystery, crime and action alongside character development to create a perfect mix for the viewer !

What can I say about Ji Sung!!!! He is one of the most finest actor in korea and one of my favourite..... His choice of scripts are marvelous.....He never disappointments.....The plot and twist of the drama will hook you up till the end.....You will not feel bore or anything.... A perfect script with perfect and finest casting.... I would recommend this drama to everyone.... This is a family drama that you can watch with your full family.....There is no nudity or anything, anyone can watch.... Hope to see more variety drama from Ji sung.....and congratulations everyone who worked hard on this drama.

It's another masterpiece of Ji Sung ssi. It has a great plot and all the actors are very good. Especially actor Ji Sung's drug-addicted acting makes the me exhausted.

From first ep and go on, the rate of the film did not slow down, and the desire to continue watching could not be stopped until the end. 14 episode is not enough for me. If it's possible I want to get season 2.

I would definitely recommend watching this great drama. The drama carried the curiosity with some unexpected twists buried in it.

And the characters in it also feel very close to the real world especially Jan Mido's cha.

This show is too good. Really good story. I don't remember any plot holes.

I was not sure if I should watch it since the rating is not that good, 7.9 at the moment. However, for some reason I felt I should give it a try, and it was totally worth it.

I liked the characters and the story. Until the last moment you are not really sure what happened.

Not much violence, some fights, some drugs, but I'm not sure if it is even moderate, maybe just mild.

I really like the interpretation of the main character, it seemed really good. I prefer this show than Stranger, which has a better rating. This one is far better.
