I really don’t know where to begin with this drama’s review, because I’m so conflicted. On one hand I think that it was good because it wasn’t boring, but on the other hand there are so many holes and unsolved mysteries in the plot that it really ticks me off. The story isn’t bad once you realize that the whole plot is based on Dr. Jin trying to save the girl. All the rest is just his journey as he tries to achieve his goal. There are so many holes in this time jump story that it becomes ridiculous. So, I say just ignore all of that and enjoy it for what it is. Honestly, Dr. Jin wasn’t my focus in this drama anyway. I spent most of my time concerned with Kyung Tak, which is the son of the “bad guy” in this drama. Kim Jae Joong plays Kyung Tak to perfection. I felt more deeply for this character than any of the other characters. He stole the show!!! I gave the acting a higher rating based mostly on him. Song Seung Hun is Dr. Jin and he does a good job, but I didn’t really care what happened to his character after a while. They don’t really explain anything anyway. Park Min Young acts well and is as pretty as ever. I liked both of the characters she plays although you only get glimpses of her as Mi Na. Lee Won Jong who plays Joo Pal is in like a ton of dramas and he always does a good job, but seriously…how many dramas can a man do in one year??? It is crazy!!! The music is fine, but nothing that I remember. I guess I recommend this drama to people that like historical dramas and medical dramas. I don’t enjoy either, so I’m not sure why I watched this in the first place. LOL However, I am happy because I really enjoyed Jae Joong and look forward to seeing him in more dramas.
