That's exactly what I did. I was very reluctant watching this because of the mixed reviews and simply because the cover photo turned me off. I'm glad I told myself to stop doubting it and to watch at least the first 30 minutes. 30 minutes turned into an hour, and hour to 2 hours, and so forth.

I was moved down to the core significantly from the cult-like ominous groups that corrupted Yu's family. It has made me realize that even today groups like this exist. Personally, I grew up forced into Christian beliefs and had to put up a fight to state my own opinion against it since I'm even still under the age of 18.

The acting the actors portrayed could've carried this movie if the storyline wasn't good. These actors amazingly outdid themselves and I will DEFINITELY watch more productions in which the main cast has starred in.

It wasn't really until the ending that made me show emotion, though. when Yoko realized that all along she was in the wrong, and when Yu was in the psychiatric ward, she went to do what he tried to do for her.
This movie is so hard to explain emotionally, you REALLY have to watch it yourself to see what I mean by all this.

Worth the 4 hours.
10/10 from me.
