I strongly encourage you to NOT watch this.
I don't know why this movie has as many positive reviews as it does. I try to be unbiased with any reviews I give, and this movie is just not it.
I can tell that they put a lot of work and time into this movie, but what for? This movie is just unhinged and screwed up. I like to pick apart movies and get into the depth of their details and meanings, but I can't do that this one. It seems as if it's only purpose is to make you feel unsettled, grossed out, and questioning.
You might be curious and want to see what this is all about. Don't. It's not worth it. The movie has no positive outcomes of watching.
