This series makes full use of the premise in a creative and emotionally involving way. I was surprised how the dynamic of the relationships between the humans and the robot became quite complex and interesting. The series starts off with pretty Czech scenery. Then there are some action sequences that are quite okay for a TV show - not cheap feeling. I was irritated at first by the female lead played by Gong Seung-yeon. Her character was not very likeable and irritating at times. But things got better when the romance started - yes a believable romance between a human and a robot. Liked the way they show the humans with flaws and greed and the robot all better than them. Later when the rivalry starts between the human and the robot it gets interesting. The director and actor do a good job of differentiating the human and robot in the later parts. The cast is good. Seo Kang Joon looks the part and acts quite well with the right amount of robot like expression and later more emotional as a human. Lee Joon Hyuk of City Hunter is quite well cast as the loyal assistant. The climax is quite exciting - some series falter towards the end but this one doesn't. The settings are quite attractive and things are nicely filmed. 18 episodes was a bit long. 16 would have sufficed.
