This is one of the best shows I have *ever* seen. I was, and continue to be, blown away by Lee Joon Gi's authentic portrayal of the tortured main character and Moon Chae Won's work alongside him as his wife and the cop who loves him so purely. Heart wrenching and ultimately absolutely beautiful.
I am thankful to all who put so much into its making. :) What a treasure.
(As a little aside, I was astounded by the scenes where you see just how deeply the main character, who is supposed to be unfeeling, cares for his wife. Watching those scenes was a punch in the heart, and I don't think I'm ever going to forget them. Huge kudos yet again to Lee Joon Gi and Moon Chae Won for that.
Oh, another little aside - I also really enjoyed Reporter Kim Moo Jin, and his relationship with Do Hae Soo. The guy who played the reporter was very good, and provided much needed comedic relief ;)
