There are so few good movies out there that explore power exchange. BDSM porn is useless to me, in most cases, since it's incredibly contrived and the actors so rarely enjoy their roles or the activities they're performing. What's more, the eroticism just isn't there in most cases. And for me, BDSM is about eroticism. Power exchange isn't matter of fact: it's erotic. Devastatingly so. I crave the ability to see that on screen.
