I think I might be the only one on MDL who actually enjoyed Dr.Jin...come on ppl it wasn't that bad...it had the regular Sageuk politics (this time with a totally new subject) with a very valuable medicinal info (as a pharmacist-to-be I was thrilled when they made penicillin)...the acting was more than good it had 5 amazing leads each of them can lead a drama on his/her own (Song Seung Hun - Lee Bum Soo - Park Min Young - Lee So Yeon - Kim Jae Joong)...the supporting characters were also interesting...and the idea of changing history was pretty unique...you can't find it in other time travel dramas... * the only bad thing about this drama is that the time travel thing was missed up...so what it's just an hour in 22 hours...this drama is mainly a Sageuk so If you don't like Segeuks you won't like it...otherwise I don't think it's that bad - at least for me it wasn't a waste of time ^.^ * the OST was good * I'll re-watch it few years from now ***PS: I did a research about the historical background of the drama & I've got to say that I really appreciate what the writer & Lee Bum Soo did to Lee Ha Eung's role...they did a great job turning that evil man who killed thousands of Koreans for their religion to such a sweet person who wouldn't change his morals (I get now why Lee Bum Soo accepted that role after his success in History Of Salaryman) *hope that was helpful :)
