Why do women like 50 shades of grey? No dudes, unless you're going to be analytical about it.?

Since the consumer base is primarily female, please no dudes just taking the opportunity to be a ****, you can do that anywhere, anytime, take a day off. I want to know exactly why you could like this film?

Like I never bashed on twilight, because I can understand the reality- a female character with little personality is obsessed over by several attractive males who are obsessed with making her happy is like the female equivilent of porn. And it's ironic how people revolt at anything so obviously geared towards women when there's so much penis pleasing testosterone infested BS with no plot out there like Transformers But it's all fantasy right?

But I cannot understand how people could fantasize about a man who treats her like a posession, and has a binder filled with women he's dated and their SIN information. I had someone else tell me the books tried to make it look like dating batman, but I need to hear what more women like about it.
