This started off with dialogue so bad, i thought it would end up as the drama i gave the lowest rating so far to. Episode 2, didn't raise my hopes too much. There is a silly chase around a pillar, which I don't think was meant to be funny. But as the show got on, it got better. It seemed to be a show that wanted to tick as many Korean type dramas as possible from extreme violence to more light hearted fare, and in between. It was only as the show went on and no longer seemed to be going for extremes that it found it's footing, or perhaps I just got used to it. Acting wise. I thought Kang So-Ra was terrific, followed by Cheon Ho-Jin, who made a great villain. In I suppose in what was the nominal female role, Jin Se-Yeon was fine. But she's probably not as good an actress as Kang So-Ra. In the lead role, Lee Jong-Suk, came across as being one of the better pretty boy actors out there. Although I really had to use my imagination to think of him as a doctor, especially when he had that HAIR. What I was a bit confused by, was who was the main female lead. Was it Kang So-Ra, or Jin Se-Yeon. To me it was Kang So-Ra, and the playful scenes between her and Lee Jong-Suk were some of the best in the series. Park Hae-Jin's performance came across as being rather one note, but maybe that was the character he played. Choi Jung-Woo could have done with toning down his performance at times. The acting from the rest of the cast ranged from adequate to good, and better.
