Romantic Doctor Teacher Kim 3 is probably the weakest season and yet it manages to deliver great performances, character development and music. It ends the main story perfectly and even leaves the opportunity for another season open. Well done.

I particularly liked how Nurse Eun-tak and Dr. Jung had a chance to shine this season, with their own storylines, and not as supportive characters only. I also appreciate the full circle moment of having former cast members comeback for important guest roles. This story is no longer about Kim Sabu teaching his younger colleagues, but those former students teaching others now. Wonderful.

Full disclosure: it was difficult for me to watch this season without having to fast forward scenes featuring an actor who I know is a piece of ? IRL. I find contradictory this person was cast on a tv show where ethic behaviour serves at the backbone for Kim Sabu's teachings, personality and other characters's arc. Do better, show. Stay away from that one actor in the future.

You might be wondering, why comment on this? Because as a viewer it changed my experience of this drama. A drama I have been following since it aired its first season in 2016. On this season, when this particular actor was on the screen, I found it nauseating and annoying. Once he was gone, a little over midway in the season, things got far more interesting and the story even better. The show ended strong because he was not there.

If producers and writers are making plans for a fourth season, they should consider not hiring this man again. It distroys everything he touches.
