I don’t know why but the rates are not very high. I love this drama! It’s a bit long but I think it is worth watching. First of all, I enjoyed this drama because it’s an historical drama. Though there isn’t romance, it has a touch of modernity because of Jin. In the historical part it’s interesting to see how people used to live and see how there is so much of conspiracy in a court. The political part is really good. The drama may be a bit boring because problems arise, calm down and then arise again!! It’s repetitive sometimes. But despite this, Time Slip Dr. Jin is a worth watching drama!! The acting is also really good. As the main characters you have Lee Bum Soo who did an awesome performance. In my opinion he is the heart of the drama. I was also surprised by the acting skills of Kim Jae Joong. You must really watch it for yourselves! Don't listen to the rates. Just watch it!
