Flimmy Read the book and you'll see what I mean.
I've read lots of fantasy books about BDSM and found pain, love, consent, kink, consensual non-consent, roleplay, trust, communication, respect, filth, sex and loads more. I've never read a BDSM book where the Dom actually abuses the sub without her consent.
I've also read lots of fantasy books about abuse or rape, take The Sleeping Beauty Trilogy, or Kushiels Dart, The Wolf and the Dove where the female is raped by the man she eventually falls in love with or Stormfire where shes beaten by her soon to be soulmate. I've found "real" non-consent, real "abuse", real "headfuck" situations. None of these books try to portray themselves as a BDSM relationship.
50 shades crosses the line because it fits into neither of these and both of these at the same time. Because essentially what it does is take the examples in the last category I mentioned, and gives itself the "BDSM" category.
Yes its a fantasy, and yes most women know how to differentiate between fantasy and real life, and yes its brilliant that women's actual fantasies who many would think should be suppressed are given some screentime.
But- dress it up as a film which indulges women with abusive fantasies. Don't release it on valentines day as some sort of love story and say its BDSM because its not. And what that does is blur the lines between Kink, and real abuse. If it was kink, he would make sure everything was sane, safe and consensual. If it was abuse, it would be marketed that way.
Marketing abuse as a sane safe consensual BDSM relationship is wrong and completely irresponsible in my opinion.
