Can't believe there are still people who don't know 50 Shades of Grey is a Twilight fanfic reprinted with the names changed.
I think frankly that everyone involved in bringing it before the public in the guise of a legitimate original work should be thoroughly ashamed of themselves - I don't mean the readers duped by the hype, as everyone is suckered by hype sometimes, and I am definitely not dissing the content for being sexual, but for being unoriginal, unbelievably badly written and misguided about the sexual universe it claims to describe.
It's plagiaristic, endangers the fanfic community (especially if Stephenie Meyer ever wakes up and takes action), and it's utter shite.
And as BDSM goes, it is utterly and criminally irresponsible, both for failing to use the most elementary safety precautions and for dissing BDSM as sadism, which it bloody ISN'T. I'm not in that world myself, but I have friends who are... and I lost a colleague to it a few years ago, to self-strangulation.
My views are admittedly based on the fanfic, which I read a while ago, but I gather that the 'book' is 86% the same as the fanfic, and that most of those changes are name-changes (Bella is Ana, Edward is Christian).
What cheered me up is the emerging parody - 51 Shades... Google for it.
