While I have not finished this drama series (it is still currently being aired), I have enjoyed what I have seen thus far. I did not care much for the early episodes with the young characters, though I do understand that these episodes were important so that you can understand the history of the characters. Story The story is different compared to the other dramas I've watched, though that doesn't mean there aren't moments that have that dramatic flourish of being almost completely unrealistic. However, in the 10 episodes I've watched, there actually hasn't been as much progress as I would have hoped being this far into the series. Acting/Cast Kim Bum, oh my goodness he is perfectly cast for this. The moment he makes his appearance as the older Tae Do you will swoon. Moon Geun Young as Yoo Jung Yi is also very good as she does translate the characteristics of the younger version of herself fluidly. Music I really haven't paid much attention to the music and so far the OST doesn't have a song I would want as part of my music collection. Rewatch Value This is a long series. I probably wouldn't rewatch it for a long time for this simple fact. Though Kim Bum would bring me back for sure.
