I don't really think I can write something about it. It was really, really intense, but I will try to write as much passive as I can.
The story is nothing new, is a type of Hunger Games more or less, the plot even the whole building of the characters and their relationships. But actually it is a analogy to our world, where a lot of people believe that they can step in the bodies of others to succeed and they do it. But in the end, if you are poor, you have to stay like that and the rich dectate your life... Maybe this is my own interpretation. This analogy, this absolutely crazy story is trying, with the most horific way, to tell that this isn't the solution. Even if you step on everyone, this system is designed for you to fail or to became on of them.

Ok, in the more prominent staff. Exceptional shots, photography, scenery (the colourful stairs, oh my god). And also amazing music and acting. At last, I really don't think it needs a season 2 (nothing official, just the way it ends it surely gives that vide). Some stories need a final end. And it is enough. But, with all this success (do you know how huge is for a k-drama be no1 in Greece? Here, they don't even acknowledge BTS' success), I'm almost sure they will continue. And I really, really don't want that.
