Story: As in the two seasons before Han Jin-woo and a team of medical experts continue to solve cases involving rare diseases. But the new detecting in charge, Bae Tae-shik, and Jin-woo just won't get along and tend to end up arguing often. As they solve different cases, Han Jin-woo seems to change a lot while getting involved with a rather specific case on his own.
Cast: Let's say that there are some actors that appeared in the first seasons as well. Except for Ryu Deok-hwan as Han Jin-woo - that change of hairstyle though - there are Choi Jung-woo as Jang Kyu-tae, Park Joon-myun as Jo Young-shil and Na Yoon (or Kim Dae-jin) as Kim Sung-do left. I think I've commented on their acting enough already but especially for Ryu Deok-hwan this season was a good opportunity to show a completely different side of Han Jin-woo and therefore his acting.
New in the main cast of this series is Ahn Nae-sang as Bae Tae-shik and he's just what you imagine a veteran detective to be like, especially when it comes to his instincts. But especially at the end of this season you can also see a rather soft side of his character caring for the members of his team like he would care for a family.
Another new addition to the cast is Park Hee-bon as Lee Ran (pronounced as Iran which made me randomly laugh during the first episode). While I thought her character was too bubbly especially in the earlier episodes, I wonder about her background story. It's not like the audience gets that many hints when it's about a character that doesn't appear all the time. And we can't forget about Han Seo-jin as Yoo So-yi. While she's not one of the main characters, she becomes more important in Ep. 8 I think because - without her and Sung-do the team probably wouldn't have known about the case at all.
Oh, and Ko Gyung-pyo has to be mentioned as Seo In-gak since the last two episodes wouldn't make sense without him at all. I knew him because of Flower Boy Next Door but this series shows a completely different side of his acting which is indeed good.
Soundtrack: As it is rather typical for OCN series, the soundtrack is a lot shorter than those for the first seasons and the main focus is put on the story. Though OCN definitely knows how to use instrumentals to highlight the atmosphere, I sometimes miss the songs one would start to love. But that's just a general side note and I seriously loved the fact that Hlin performed a song again, this time called "비밀 (Secret)". Though I personally enjoyed the soundtrack a lot, those who prefer listening to 'real' K-Pop might not like it that much.
After all I found this season to be good, especially Episode 4 hit me harder than I expected any episode of this series could but especially the first episodes until Episode 5 and episodes 10 to 12 were interesting but in the middle I found myself yawning from time to time. Sure the cases were interesting but I know that they can do better. Also it's a shame the comedic part added mostly in Episode 1 with Detective Bae and Dr. Han not getting along at all and arguing in a funny manner disappeared.
Oh, and I just need to get rid of this weight but - I hate extremely religious people. All the talk about God and an alternative in season 2 already bothered me but this time there was this Episode (I think it was Ep. 8?) and I wanted to just skip the whole episode.. but then again not everyone might be that annoyed by that talk.
9.5/10 therefore is my rating of this season, and though many people consider it the best, I'd still go for the second season as my personal favorite. It's worth a watch though and if you really don't like a few things there's still the opportunity to skip some scenes.
