the biggest issue that I've with this drama is that it tries to be wanna be western criminal drama. production company can hire great cast led by an amazing director, but if writing is horrible, rest of the hard work doesn't matter.
also, why do men write women so stereotypically in kdramas? it's painful to watch. generally, i don't give a f*ck how these sorry excuses of men live. they're all dislikable to some degree
