I haven't seen any of this series but considered adding to my plan to watch list. My first thought when i read this review was "could his his sister actually be the monster?"
I actually think this series is really overhyped and the story itself was somewhat mediocre. The production and acting were both very good to excellent. I think there are other series that are far more deserving of more attention. However, it's good to see a kdrama doing so well internationally. Also, great job on this article.
Their native names or screen name everyone views during their dramas should be used for identity on mdl. Many actors may have an english name but who searches for it? Do we even know it? I had to actually go to some of the actors dramas to even find them. Search Yang Zi for instance and search results are negative. I speak english as a first or native language but have never once tried to find a celebrity online from what is essentially a nickname.
