Likes:
1. I appreciate acupuncture now thay i know something about it
2. Like how they showed that both traditional acupuncture and modern hospital can help save lives
3. I liked the character development and romance between of Heo Im and Yeon Kyung
4. The whole time travel always came ay the right time but sad that Heo Im have to kill himself over and over again to do it
5. Loved the scene where Heo Im was crying after Duchil's brothers death. That was one emotional scene. Actually any scene where KNG and KAJ were crying were so good. KNG is seriously going up my list as one of my fave actors.

Dislikes:
1. Not much really. Sometimes the parallel story in Seoul and Joseon can get cheesy but it's ok because they needed to learn their lesson
2. We dont really know where the magic needles came from
3. Wish Makgae had more screen time
