This has been the only k-show I've ever seen where I was not bored. Every minute of it kept me interested and on the edge of my seat. The show is ruthless with it's characters and that is something that makes this show so unique. The production is fantastic and these scenes are very cool. The storyline itself is so interesting and makes me think about how many good people are there really in this world.
One thing that I didn't like about it was the weird ending, it felt abrupt other than that throughout the whole thing it never got old or went down in interest level.
