This really deserves a 10 rating; it really is closer to 9.5. The ending could have been a little bit more satisfying but what I will take away from this is the director's ability to put together scenes that we, the viewer will NEVER forget. I don't think I need to spoiler and mention any. I believe when you watch this, every one of those scenes will be fresh and new; things you have NEVER, NEVER seen before in a drama! Every single one of the main leads gave a STELLAR performance. From Ji Sung and Hwang Jung Eum to Bae Soo Bin to Lee Dae Hee; all were at the top of their game! Am I going to watch this again? You damn right!!
