I watched this movie with a group last night who is familiar with BDSM. Personally, I feel the movie did BDSM an injustice. If I did not know better I would think that in order for someone to become involved in a "power exchange," they would have to be enticed with big money or some reason other than their need to be in a supportive and loving environment. A true BDSM relationship involves a "power exchange" which comes from the person's need to submit, a gift of submission to their Master or Dominant.
By mixing in the slave trade it only misinformed those who have no knowledge of this type of relationship, and who try to use fear tactics to make us look as if we are a danger to society. In no way did I feel that the movie showed any type of a growing relationship that would justify anyone giving up the degree of control that was displayed. Her devotion was bought and paid for.
One comment from the audience was that the acting was comparable to a porno flick. Being knowledgeable as to the true relationships involved in BDSM we could see through the errors. For someone not familiar, it would only make them think that BDSM is a horrible thing. I would not recommend this movie to anyone outside of the BDSM scene.
