Very satisfying ending and love the back and forth show off of the intellectual wit among players. Both the hero and the villain's characters are interesting, and so do a lot of the supporting characters. They all have a story and the plot somehow can seamlessly insert these characters into the bigger scheme (the whole plot).
This is the second time I watched Nam Kung Min, the first one was a romantic drama and was a total disappointment. After watching Doctor Prisoner, I can conclude that Mr. Nam is best suited for more complex role rather than some simple cheesy romance lead. This guy seriously has a strong presence, good acting and poise as a doctor or any other strong roles. Compare to him, the female lead, Kwon Nara (of Itaewon Class) seriously need to polish her acting skills, she hasn't improved a bit since Itaewon, the same no emotion expression and stony face.
Actually the story is simple but they managed to make this series interesting and have audience looking forward to the next episode. I totally enjoy this series and hope can see more of this kind of clever plot TV show.
