The first few episodes were interesting, but then I started realizing how frustrating all the characters in it are. People die for almost no reason, they give a kind of stupid end to an annoying character. Not to mention the ending of the series being extremely lackluster, it almost didn't feel like an ending.

Overall this drama was extremely frustrating to watch, and wasn't worth it in the end. the actors were pretty good, but the writing was awful, and made almost no sense how some peopele can be so dumb.

Save yourself the trouble and don't watch this drama, go watch Healer, which has vastly superior film making, better action, much better story and writing. And a satisfying end.

I would describe this drama as Healer, with everything good about it stripped away, and only the frustrating parts left

The entire time I watched this I felt anxious, because I was waiting for any character to do some stupid shit that would get them in trouble, then proceed to dig themselves a deeper hole, and drag more people into it.

The only 2 redeeming qualities of this drama are Kim Sang-ho, and Park Min-young.
