I was so amazed with this drama. I also learned a lot of things. Even if SJK was not the ML I would still watch this probably just + points in advertising this drama in his name. Only negative thing I can say is the plot. From start until the ep before the finale they built up the 'Reborn' character of Jin Do Jun and made the watchers empathize and cheer for him to take over the Soonyang Group and when it's already in his hands they took it away like a taking away a candy from a child. The watchers will be pissed including me.
Excluding the final ep, this is still a masterpiece. I love the mind games!
