As I began my journey into kdrama, I remember reading that I should never expect any of the medical aspects of the drama to make sense (I don't recall where I read that). If you go into this drama with that knowledge, you are more apt to enjoy it.

Here we have another solid performance (of weak material) from Hyun Bin. As always, I particularly enjoyed his transition from mean chaebol to caring man - one of my favorite moments was when he jumped onto the roof of the cart when a certain something happened to get loose at the amusement park. We all know how well he is able to play both sides of the chaebol coin.

Han Ji Min's performance was adequate, but it lacked any sort of spark. Part of that was due to the weak writing (the premise was interesting, but the script itself was lacking), and part of that was due to her choiceses an actor.

This drama was my first introduction to Bang Sung Joon (now a personal favorite of mine), and his performance of less than mediocre material was good. I appreciated that he played the antagonist in a way that wasn't quite heavy handed (his moments with his hostage could have been played in a very one-leveled way, but he chose to create a more realistic kind of gray area (granted, it was dark gray) villain. One thing that I love about Sung Joon, which was evident in this drama, is that he is able to portray darkness in a way that can be frightening without going overboard.

Production values were also a bit weak with this drama (the circus scenes were a bit bland and low-budget, in particular).

Overall, Hyun Bin and Sung Joon carry this drama.
