I want to be very clear: this is a superb series for whomever is looking for a westerner, social + romantic, full of very very interesting ideas type one. However, the problem is that k-drama watchers are mostly the ones watching it, so the rating is low because of this: they expect a nice bubbly story, with all kind of hidden relations that are going to be revealed in the end, full of romantic, unexpected turns, so of course, for them this is going to be boring. Again, the series is superb, depicting perfectly the social segregation, power abuse, difficult to reach relations, but the final idea that a relation should be stopped after an amazing climax has been reached is stunning (and it's so very difficult to stop...) despite there are counterexamples when two people live happily ever after (yes, you can count them on the fingers of a single hand, but... there are!!). An excellent director, who used picturesque effects to show a large variety of feelings on the screen. It's absolutely everything else but boring!
