If you fancy "adult entertainment" (as "art", as "erotica", as "cinema"...whatever), and aren't a "pervert", then you'll like this doc. It's hosted by the vivacious (great 'word for the day') Chanel Preston, and basically plots the evolution/transformation of feature-length sex movies since the early 1920s. NOte: this is an R-rated documentary about the X-rated film industry. Several directors and actors from the best known of the movies since the 70s are interviewed (along with a few contemporary performers), and the interviews are enlightening if for no other reason than that they show people who had/have fun doing what they did/do, and who are sincerely trying raise their genre of movies to another level.
