I read the comments on MDL and honestly, I feel sorry for those people who dropped this. They just missed one good hell of a story.

Story:
There are a lot of lines about sacrifice in this drama. Lovers sacrifice for their other half, family members for their loved ones, soldiers for their country and fellowmen, and doctors for their patients. For me, sacrifice is a really big thing and something that is hard to do and the fact that this drama has shown the different sides of sacrifice, already makes it a good drama. I didn't find it boring at all -- or probably some Mi Gu and Zhou Ran parts (read below). The story was very similar to You Are My Hero. One difference is in MDG, they had one enemy which they need to catch/destroy. In YAMH, there is no constant enemy but the couple meets a lot of danger together. But in terms of loyalty, friendship, sacrifice, love, family, and others, I could see a lot of similarities. And I actually think soldier/police-doctor stories is my thing now. I l loved DOTS, YAMH, and MDG. Hope it trends more.

[SPOILER] I'll talk about the couples now, probably spoilers.
1st couple, as a hopeless romantic, I was a little bit disappointed with the romance 'cause I was expecting more from Johnny Huang since he's had a great chemistry with his female leads. The main leads also had good chemistry, I just wish for more. Oh, and the way he just stares at her sometimes, already was full of meaning, he just needed his little cousin as interpreter 'cause the FL was a little dense.
2nd couple, Mi Gu and Zhou Ran... Personally, I dislike girls who fall head over heels guys and just lose their sanity and sense of reality. I felt so bad for them at the end, but it was something that was bound to happen. They were never going to end up together.
3rd couple, Dr Zhang and Meng Zhen, I loved Dr Zhang! How he was a playboy at first but became serious for Meng Zhen. He was really just searching and waiting for the right one. I also felt bad when they almost didn't end up together but I'm glad he came around, thanks to Xiao Jun, and the gossiping ladies at the canteen. As for the girl, I kind of wasn't convinced how she pushed away Dr. Zhang, comparing him to her first husband. Honestly, there's really no good in comparing things, in all aspects. Of course, they weren't going to be the same! You know, if it's love, it's love.
4th couple, my fave, but the saddest. Tian Yong and Xue, OMG, there are no words to describe them honestly. They were perfect for each other even if I think they have a huge age gap. There also no words other than devastation for this couple. My heart still aches when I think about it. I kind of saw it coming but I still hoped for the best. She actually deserves him, she needed someone as true and naive as he is, but sadly, it wasn't meant to be. It just hurts.

[CHARACTERS]
- Main FL. A lot of people found her annoying. At first, I also did. But damn, her principles and passion as doctor, really touched me. She could be a coward sometimes but the care she has shown to her patients was really something. I think she was the only doctor in the whole drama who was like that. The other doctors were actually a little bit selfish, and that was even more annoying.
- Tian Yong: I LOVED HIM, definitely one of my faves in this drama. Again, it's just so sad what happened to him, so unfair.
- The other resident doctor: I HATE HER. She was one of those doctors who were super selfish. TBH, most of he doctors in this drama were selfish, but her in particular. I disliked how she went back and forth, enemy then friend to the FL. Even if she explained herself at the end, I still dont like her.
- Dr Zhang's ex: Most selfish doctor. PERIOD.

My review was super long, but it was more like comments than a review. Overall, it's good drama! Just watch it. ;)
