Look - the books are pretty trashy - but it's important not to overthink the message sometimes. I don't think it will result in a revolution where woman are tied up and flogged for some blokes kicks.

When I was in my teens couldn't imagine any sort of kink in the bedroom, but as I get older my horizons have got broader, and let's say that thrills come in many guises - and it doesn't mean losing control over the situation, nor losing respect.
With this movie and books - yes - they are trashy - but let's just
about them.
