The real Fifty shades of grey ;-)

Today I saw the movie "Fifty shades of grey" with a good friend. I didn't regret going, it was quite intriguing though. I didn't only see it as a movie with SM in it, no... there is a story behind the fact that Mr. Grey is what he now is.
Keeping apart the erotic part, the crux of this romantic series is how a person coming from a cruel and bitter background changes completely into someone absolutely different from what he has been all his life just because of true love....
