Doctor Prisoner

Live Up to Your Name! I will never not recommend this drama when it is even a little bit relevant. Dr. Heo is a legendary doctor!

I also just finished Chocolate, and Kang is a pretty amazing doctor, though I'm not sure he falls into this geeenius category, haha!

The first show that came up in my mind is Dr Romantic 1 and 2! I LOVED Kim Sabu and I’m thinking of rewatching them soon!

Ghost Doctor for me. I loved the bromance as well as the genius surgeon part.

Awwww, just want to give a shout-out to the term “geeeenius” (doctors/lawyers/whatevers) which originated back in the DB days of Javabeans and Girlfriday.
I’m now trying to remember female characters who have been geeeeniuses? 🤔 Maybe Dae Jang Geum for starters?

There is no shortage of geeenius doctors in k-dramaland. There is at least one every year, but I want to recommend recently aired c-drama Dr. Tang.
The first and foremost reason is, it features a genius female doctor in her late 30s -nearing to 40. She is certainly smarter than rest of cardiac surgeons but at no point we feel that it is God-gifted. She has earned her genius credentials by being hard-working and putting her career /being doctor first.
It could be debatable whether she is genius or not if you her compare with male counter-parts but she becomes head of cardiac surgery at 38 in one of Country’s leading hospitals and she leads team which successfully develops fully-indigenous artificial heart. That counts as being a geeenius, right?

Doctors @ White Tower

Doctor Stranger because it's so so bad that it's almost "so bad it's good".

Grey's Anatomy 😌

Han Seok Kyu in Romantic Doctor teacher Kim 1-2. Being TRIPLE surgical boarded is no easy feat. But what made him a geeeenius what that he was a SURGEON with a HIGH EMOTIONAL QUOTIENT.

Rain in Ghost Doctor. Still won’t beat Han Seok Kyu though. Only single boarded. Low EQ (until he becomes a ghost).. 😂

I’m in a minority but I really liked Dr John

Hands down, Romantic Doctor Kim 1 and 2!!!! And my husband and I thoroughly enjoyed this compelling drama! Dr Han is amazing!

I really shouldn't be recommending shows that exist only on dodgy streaming sites with slightly iffy fansubs, but the three seasons of the J-drama called (with great originality) DOCTORS are really pretty good.

Structurally it's rather similar to Doctor Romantic, with a main character who is invincible in his competence and integrity. In each show, the protagonist tries to raise standards at his hospital while dealing with colleagues who are more interested in status, prestige and money than in their patients. While Dr Sagara's antagonists seem outrageously buffoonish, I've got to say that DOCTORS in general seems more realistic and much less melodramatic than Doctor Romantic.

For instance, Master Kim is presented as an almost mythical rebel whose skills are so extraordinary that other docs are constantly marvelling at or questioning his diagnoses. What Kim reveals to his disciples at the end of Season 2 after a long period of unnecessary mystification is actually laughably obvious - those skills have been acquired via studying and practice. In contrast, from the start Sagara is shown doing research; discussing cases with other doctors and also nurses; and reminding junior colleagues to never rest on their laurels. The character is also more interesting because he seldom grandstands or openly opposes the status quo. In fact, Sagara is quite a cold fish, and though his ends are always good, his means are decidedly Machiavellian.

Of course Sawamura Ikki is no Han Seok-kyu. But much as I adore HSK and his Master Kim (especially when he is listening to Madonna on cassette tape), I prefer Sawamura's close-hearted but single-minded Sagara. It really is a pity that DOCTORS is not widely known.
