Agreed, moralizing should never be the domain of documentary. If you saw Theroux's
first doc and his exceptional
*followup*, he's always a bit cold, but he engages people with authenticity and fairness or not at all. Although you might actually know Rob Black, Kagney Lynn Carter, etc. and I do not, I can completely relate as an outsider to Tommy Gunn because the conversations are so sincere.
What I liked about 'Hot Girls Wanted' was that the actresses speak for themselves, and it follows three (Ava Taylor, for example).
After Porn Ends (2012) was also sort of interesting.
