The reality is that the whole concept behind this movie is banal and pathetic. Hollywood would never show a truly controversial movie about sex. So you get this nonsense that is silly in its attempts to be suggestive. They did it back in the 1990s with Exit to Eden. Does anyone remember that laughable bomb. It was so bad that it wasn't even unintentionally funny.
The right reaction to these types of movies that hype sexual “edginess” is to call them out as pathetic attempts to market something that isn't there. There is nothing liberating about what the book describes and the movie suggests. Its just boring once the titillation wears off. But for the brief moment that the titillation exists, they are going to try to sucker the public into paying to see it.
Isn’t this just another “The Story of O” but with worse writing?
