This movie was great beginning to end, believe it or not it had lot's of artfulness in it, great camera work, and story. A dark satirical comedy more than a horror.
I don't think women will like this, or sheltered men, but men that have actually experienced some of the joys and miseries of life, will relate with guilty pleasure deeply to certain scenes of this movie. 9/10
Minus the psychotic nature of the Dr, it's very redpill, definitely. All must be aware that women are very capable of doing this to you (cheating on you and taking everything you've worked for), so protect your three A's: Ahhs (house), Assets, and Ass.
I gave the movie a 7/10; original, and the base story (of the female infidel crisis) was realistic. Like you say, women and sheltered men wouldn't understand and just focus on the physical 'horror' aspect of the movie, but any man who has gone through being cheated on or at least has solid foundations in the nature of women will understand this movie.
