First of all, each episode was like a separate movie, kept my interest for all 16 episodes which rarely happens! Even though there was some violence etc, there was always some comedic relief by some of the side characters. All actors were great, but especially Ahn Bo-hyun was perfect for this part!!
I hadn't seen Kim Woo-seok before but he was great in portraying the process of his character change and all the emotions it involved.
Korean Ensemble shows like this one are great when they're good. Even though the theme is different, it reminded me of other successful ensemble series like Diary Of A Prosecutor, Hyena, Good Manager, and many more I won't list right now, which are classics and all time favorites. And I'm glad I decided to give this one a try!
Just a note, even though I loved it I watched it at 1.25 speed, but I do that with most dramas. So if you find it a bit slow that's no reason to give up on it, just speed it up a bit!
