I really liked the first 6 episodes, but honestly I really did not like the middle episodes (ep 7-12ish?) -it took me forever to drag myself to even watch the end of this drama because I disliked the middle episodes so much. However, the last few episodes were amazing. I thought the whole story was really well done overall, but the middle episodes could have used some teaking. This is very unique compared to most other K-dramas even though the premise is very similar. Music was very good from what I remember and the acting was superb. I most likely will rewatch this drama, but I may skip some of the middle episods since they just didn't jive with my taste. I loved all the stunt team action and the main lead was did so well with his character's quirky nature (tracksuits anyone? lol XD).
