I really love the experience of watching any of the volumes in Tristan Taormino's "Chemistry" series, I have to fully admit. In my opinion, she takes the established gonzo genre, which is my preferred genre, and fully incorporates what would normally be behind-the-scenes elements into a wonderfully cohesive and endearing whole. And the "BTS" elements really go above and beyond what we normally see in those DVD features, which often includes some light Q&A and following the girls & guys as they get ready in hair and make-up, the photo setups and generally lounging around. What I love about "Chemistry" is the extended amount of time the performers are allowed to relax in one environment, surrounded by one group of people for the duration and what we as viewers can watch and enjoy is the genuine sense of comfort and ease displayed, whether at rest or at play.
