I hardly ever write reviews for k-dramas but I will for this show. First off, let me just start off by saying that this was one of the most well-produced, well-acted and well-written dramas that I have ever seen. From day one, the drama pulls you in and captivates you with its raw and gritty subject matter: an exploration of catastrophic religious cults. For many of us, we never get to see what goes on in a religious cult, only hearing about it on the news when something bad occurs or referring to it as a thing of the past. This show is so phenomenal because not only does it remind you that religious cults are still out there, it also makes you want to learn more about their existence. Half-way through the show, I found myself researching about the growth of religious cults within a country like South Korea that is infamous for group mentality and group thought. Religious cults are huge and this show has the guts to bring to light some of its indecencies. Admittedly, the first few episodes were very hard for me to watch because they touched upon sensitive topics like death, molestation, bullying, and the like. (And it doesn't get any easier as they explore the inner workings of the religious organization.) However, over time I slowly began to realize that those feelings of discomfort were 100% necessary in order to paint a picture and tell the story of what really happens in modern-day Korea and the world as a whole. If a piece makes you feel something, then it is doing its job correctly. My greatest hope for this show is that the situations depicted will spark a widespread transformation of Korean society. Also Side Note: I've said it before but I will say it again, OCN dramas are GOLD! Anything that is an OCN original is gonna be deep and maybe a little dark-but it's gonna be good! The 3.0 Rewatch value is because it's just one of those shows that you need only to watch once. Once is enough because, as I have said previously, it's a lot to take in.
