This drama hits hard. It doesn't pull any punches. It is true to human nature and it is true to the nature of evil. People want certain endings to evil, but evil is irrespective of our expectations. Evil must be overcome and that is all there is to it. This drama is well worth your time. There will be some moments when you can't believe that the characters are behaving so stupidly, but that, again, is life. People make stupid decisions and when they could turn the tide by making a wise decision, they don't and evil wins another battle. All in all, this is one of the best dramas I've watched. I cared about the characters, I was invested in the plot, it tugged at my heart. This drama is not formulaic, so prepare to be shocked. But if you want something fresh, this is it.
