I'll be honest. I'm not the target demographic for Fifty Shades of Grey, it just doesn't appeal to me. However, I'm open to interpretation. From what I know, the production for Fifty Shades is going very well and with a cast like Dakota Johnson and Jamie Dornan I can't see it failing. Especially since It's a subject with such a cult following.
For those unfamiliar with the plot :-
Fifty Shades of Grey traces the deepening relationship between a college graduate, Anastasia Steele, and a young business magnate, Christian Grey. It is notable for its explicitly erotic scenes featuring elements of sexual practices involving bondage/discipline, dominance/submission, and sadism/masochism
