I was very reluctant to watch Dr. John because I am not a big fan of hospital dramas. I am however a big fan of Ji Sung, and as Dr. Cha/John he doesn't disappoint. This drama is a great showcase of his talent, and this character is a unique and memorable one. The Doctor with issues genre is a little cliché but this drama does a really great job of creating an interesting story about doctors, and what ultimately motivates them, without being too sappy or cheesy. It's also best to watch without knowing anything and just trust that everything will come together and make complete sense eventually. Based on the first episode I had no idea what to expect, but one thing I knew from the very beginning, Ji Sung is awesome and that was enough for me! His abs are just an added bonus.

What I loved most about Ji Sung's performance is that Dr. Cha is often very poker-faced and hard to read, and when he was emotional it was usually very subtle where just a simple look from him, or tap of his finger, could break my heart, or get me excited. He is matched with Lee Se Young as Dr. Kang Shi Yeong, who is pretty young in comparison, so I wasn't sure if they would match well or have any chemistry. I was definitely wrong about that and she was often great at matching his subtle intensity and definitely held her own in all of their scenes together. This is less of a cute romantic pairing and more about watching two people inspire each other to be better. I really enjoyed how they worked together and complimented each other.

As for the rest of the cast, there are supporting characters that I loved and others that were a little annoying. I absolutely loved the team of doctors in the Pain unit, especially Hwang Hee as Dr. Lee Yoo Joon (aka the poor man's Gong Yoo). It felt as if I was actually watching a team bond and come together. On the flip side, I was much less interested in characters like Nurse Chae and prosecutor Son Suk Ki. I thought their story was interesting and resolved well, and I did empathize with them initially, but eventually, their actions became way too repetitive for me to continue to care. A large part of the "mystery" in this story revolves around them and they became my least favorite part of the story. I did like how the story took its time in revealing what was happening, but I wished some parts weren't dragged out for so long once things were revealed, especially in the later episodes. The last few episodes were definitely the weakest.

What I surprisingly did like a lot were the random stories of patients. They were extremely interesting, and their diagnosis was like solving mini-mysteries. Some moments are a little graphic, but never without reason. Many of them also stuck to the show's main themes about what the role of doctors can/should be and the more controversial topic of euthanasia. All of the stories are handled with respect and without heavy-handed judgment, which I think is what makes this show so thought-provoking. Maybe that's why I liked it more than I usually like other hospital dramas.

Would I watch this again? Yes, I can see myself watching this again, although I may be tempted to just skip past a few parts. Some of the mystery would definitely be gone, but it's still entertaining enough to hold my interest. I also think the soundtrack generally complimented this drama well.

Overall, I think this is a great drama to watch, even if you're not into medically-based stories because the mystery element makes it all more entertaining. The love story feels real, although it may not satisfy fans who like a strong focus on romance. It's at times heartbreaking, and frustrating, but also inspiring. The patient's stories are strong enough to override the weak hospital rivalry stories, but overall the hospital atmosphere also felt very real. I am curious about the book this is loosely based on, but I think this drama definitely stands on its own. I also don't understand why Cha translates to "John" but no matter what you call him Ji Sung nailed the role! This is yet another drama that won't be added to my favorites list, but I can't deny what this drama does well and that I am glad I watched it. By the end, I felt good, without there being an extra cheesy feel-good resolution. If you don't think you have a high threshold for dramas like this, give this one a chance, and you may be surprised like I was. I prescribe at least 4 episodes of Dr. John before making a decision. Just like this drama's themes show repeatedly, you can't always go by your first impression, and Dr, John definitely deserves a chance to really be seen, especially if you are a Ji Sung fan. If you're not, I suspect you'll become one after watching!
