Well, I've not seen his work so I can't comment on it.
Let me try to sum it up in language suitable for this forum. Young "girl-next-door" types (actresses range in age from 18 to 23 or so) wearing braces, pigtails and bright colored little-girl clothes and subjected to extremely humiliating, degrading and painful sex. It is not uncommon to see these actresses vomit and burst into tears while being filmed.
I googled and took a sneak peek - here it is summed up:
Urination
Defecation
Fisting
Choking
Rough anal sex
Gagging
All performed on teeny-bopping, middle-school looking girls.
This isn't porn, this is legalized snuff child pornography masquerading as "art."
