Foremost, having only seen Kim Nam Gil in The Fiery Priest, I love how he shows his versatility here and hoping he actually does more of the historical genre. It is his scenes in the historical setting that were the most interesting in this particular case.

Still not the greatest fan of time travel themes but this one was hilarious in the beginning. The plot had so many good things going for it along with a great cast but there was too much drag with the modern era politics (fast-forwarded most of it). They tried to portray how despite the dichotomy in era, the medical field still undergoes similar political and class issues. But they really tried to do too much in the series with the complex base of constant time travel. The series felt like it didn't know what genre it wanted to be and just mashed together a little bit of everything including the excess "cuteness" of the ML/FL romance. There's modern day politics which flips back and forth to the historical politics, prolonged scenes with patients that really didn't add much to the drama, predictable trigger events, and then add in a war with some random foreigners thrown in. If there was more focus on the main basis of the plot, it could have really been a great series. It also didn't help that they forced in a happy ending that really made no sense.

Overall, it's one of those series that's difficult to hate on but of the cast and the potential but unfortunately it's also one that's forgettable with no re-watch value.
