I too am bored by any I have seen - usually squirreled away in my son's laundry. What makes teenage boys think you won't find it in the laundry? I had no problem with him watching the stuff but had to make the point that the women in these films did not appear to be there by choice. Drugs, prostitution, poverty appeared to play a role. This was underground, raunchy, made in a local motel porn. I found myself pitying them all. I prefer my own healthy imagination and Orson Welles.
See - it works. Now I have you all imagining it.
