This will be a very long review.

In the beginning, it feels so grand. We could see how much the budget was and how big the investment they put into this season. The premise is good. We got updates on how everything is going after 3 years passed. All the surgical scenes are amazing and realistic, even better than in the previous seasons.

Each of the characters is great. The writer really knows how to make each character different and charming. They have their own story too. It's about Doldam, not only Kim Sabu, which I personally liked. However, maybe because now there are so many characters that the writer kinda lost focus on which character should get more screen time and get proper closure.
For a good example, I love how we now know what happened between Dr. Jung Insu with his family. We know since season 1 he lived separately from his family. In Season 2, he even considered the sketchy offer from Seo Woojin's senior who became a broker so he could move to Seoul and go back to his family. So it's very nice to have his full story and even a happy ending in the last episode (I LOVE his daughter. Byul is such a ball ray of happiness).
However, I'm disappointed with Park Euntak's story. I feel like it could have had better progression and closure, but they finished it in only 2 episodes and even we couldn't focus too much because of the soldier shooting story. We didn't get Yoon Ahreum and Bae Moonjung's backstory at all. I also think that Jang Donghwa also has a better development story than Lee Seonung. But the worst part is, Cha Jinman took too much screentime, and then he just disappear? Like... What's the point of building up 12 episodes and then discarding him? Also, Kang Dongju only had 4 episodes and they crammed all the problems??? I know it's not easy to build a good story so I just feel it's a pity...

I like that this season doesn't have a real villain like in the previous seasons. We just see people with clashed opinions and different personalities, which is echoing real life. They have their own reasons to feel a certain way or taking decisions due to their experiences and upbringing. When we think objectively, we could understand why they feel or behave that way. It's more in-depth. Even Kim Sabu really questioned his ideals after seeing Cha Jinman and vice versa. It's a great way to improve for the better. However, I disliked that Assemblywoman Ko became the "villain" because of his son. It's unnecessary and too heartbreaking. I think, even without that plot, the third season is still as good as it is.

Moreover, many problems are too overdramatic, like the soldier who shoots for revenge, hurting Park Euntak's "friends" but then Seo Woojin walked away unscratched like?? fr??? Also when the writer keeps making Seo Woojin in danger I sighed. Even though it's for plot devices, I just wonder why the writer make it that way. I still think the cases in S1 & 2 have better impacts with smaller problems and scales than this season, like the legendary brain death paramedic story. It's simple but very tear-jerking and heart-wrenching.

What I disliked the most is how the writer underutilized the female characters, especially Cha Eunjae. She is shaken due to his father's opinion which leads to almost table death. She need to stay strong when she heard Seo Woojin got hurt and even proceed to make her do surgery. She is just being a saint in the middle of the season when the whole hospital talking bad about his father. Even after everything she went through, she only cried in front of Seo Woojin twice. And when everything starts to become normal, the writer made Cha Eunjae clashes with Kang Dongju which led her character to get hated by the viewers. It's too much. She deserves a better story. I feel sorry for Lee Sungkyung. I also disliked how the writer barely includes Yoon Ahreum in "heroic" scenes. Also the little screentime for Nurse Oh but thankfully she got much screentime at the end of the season.

What makes me give a higher score than it actually is, is due to the execution excellence from the cast and the production team. Even though the story sometimes makes you go "huh?", their acting is convincing you. The actors are so good at their job. I totally forgot that they are actors, not real doctors or nurses. Their acting is even better than the previous season. I cried more in this season compared to the cumulative of S1&2. The cinematography leaves you in awe. The music background elevates the scenes. So it makes me forgive all the shortcomings that came from the lack of the story.

Overall, I feel like the story is inconsistent, unlike the previous season. Sometimes it feels too slow, but then things are solved too quickly. Many parts are broken and don't flow nicely. However, I understand the writer's intention in what messages she wants to convey. Still, compared to other dramas out there, this season is far better. I still recommend people to watch it. Maybe you will like it more than I do. Please give it a try, and enjoy all the romanticism of the Dr. Romantic series!
