It was based on a popular novel by Anne Rice which, while I've never read it, has been well reviewed by a number of scene people. However the movie chose to add a totally original plot line involving a murder involving Dan Akroyd and Rosie O'Donnel which obscured the love story aspect which was the main theme of the novel. You would do well to enjoy it for what it was and leave anything it says about the nature of the scene and how to do it to the vanillas for whom it was written.
