The one thing from the get-go that stands out in this drama is the protagonist. He isn't your run-of-the-mill hero. He is someone more on the dark grey side, doing questionable or even downright messed up things.

This drama is a war of wits, who gets to check-mate the other. Na Yi Je and Dr.Seon are constantly fighting to get the upper hand compared to the other. Both of them and the people surrounding them are cunning and intelligent, the story is gripping with more and more secrets being revealed at every point. The writers keep things fresh.

The actors are BRILLIANT, the cast does their job phenomenally well, Nam Goong Min is such a versatile actor, his micro expression changes to fit the mood and atmosphere, not missing a single scene is incredible. I have to say the same to the other actors as well, especially Kim Byung Chul. His psychotic expressions were on point.

Overall, Doctor Prisoner is a unique take on the revenge plotline, with a more dark take on it regarding the protagonist. You can't always face a fight by being on the white side of justice. Sometimes you have to sacrifice your humanity to gain something.

9/10.
