Watch it and judge for yourself. I’ve just finished it and loved it.
I finished it. For me, it's a good drama. It has a good premise and even a good start, but from the middle to the end I felt like things didn’t really make much sense. I almost dropped it between episodes 10 and 13. I’m not exactly sure what I expected from the ending, but I was hoping for something different than a certain person suddenly becoming a genius. I felt like some kind of explanation was missing.
