How good this movie is to you will depend on what you are looking for. If you want a movie with some nice bondage, flogging, D/s role-play then by all means its just up your ally.
But if you want some actual sex, then try another one. There was very very little actual sex in this movie. Granted the scenes themselves were very erotic, but each would end just as I thought it was really getting going.
Just my two cents.
This movie is 90 percent bondage. Not much sex goes on at all. If all you want is the tied up girls getting spanked, then this is fine. I prefer more sex in my movies. One scene was pretty intense, but too long and boring.
