I really enjoyed this drama as it covers nearly everything: "spy" work, action, fighting, romance, friendship, teamwork, family, forgiveness. The only thing I didn't like was that I felt so bad for the prosecutor and when Nana was having a hard time because of the City Hunter (am I terrible with names, I just finished this drama and I already forgot the main characters' name). There were a few other minor annoyances here and there, but otherwise the plot flowed really well. I do have to admit though that it took a bit to get me truly hooked into this drama and by that point I was watching this in marathon mode. Great acting by all parties, but especially Lee Min Ho. I have to admit it other dramas I didn't exactly "love" Lee Min Ho's acting, but in this one he just steals the cake. Also I really liked the main actress too -she did such a good job with the range of emotions and just her overall personality. Music soundtrack was great, and I am going to make myself learn some of the songs on the piano. :) Rewatch value for this drama is really good, because once you finish it you just want to go back for more! I think a sequal to this drama would be really awesome, however unfortunately I feel that a sequal wouldn't end up being nearly as good as the original. :(
