Story: 9 out of 10 - I like how the writer addressed these problems in society. Some parts made me cringe as these cases do happen in real life.
Acting/Cast: 8 out of 10
Though it's true, that Yoon Shi Yoon could have done a bit better portraying Han Kang Ho. And if the writer made the twins with opposite personalities, then naturally their appearance could have been made a little different too. I.m.h.o, Han Kang Ho's physique was too clean with overacted-gangster-demeanor that I found myself fast-forwarding several scenes. It was a bit difficult for me to continue after the first few episodes because of his acting, but I'm glad I did continue.
Music: 10/10! The music/songs are beautiful! In my humble "commoner's" ear, they fit the scenes perfectly even amplified the emotions projected in some key scenes.
All in all, for those of you who like dramas about the law, this one is definitely recommended.
