I'm so impressed of this show, to be quite honest, I didn't have big expectations seeing the rating. As soon as I started watching it, I was totally immersed, not to mention time travel is a theme that I thoroughly enjoy in each and every drama.

The story was absolutely unique and by that I mean the way the time travel was made. I enjoyed a lot the way the doctors were portrayed and the struggles they go through. The number of episodes was ideal. Again, the ending was rushed.

The character developments were so well built and I'm so glad it didn't happen just for the main characters! Kim Nam Gil as always went through a range of emotions, I never saw Kim Ah Joong in a drama before but she did an amazing job! She and Kim Nam Gil had an amazing chemistry on the screen, at times you might think they were dating in real life, that's how believable their chemistry was.

The OST was good.

My rewatch value is 9, it was such a fun show!
