What other sex or BDSM themed fiction books would you like seeing filmed
Irrespective whether you loved the 1st 50 SoG film and book trilogy, or you thought the 3 books and 1st film all sucked and/or were crap, what highly compelling, BDSM and/or sex themed fiction book/s (with similar and/or even more interesting characters to those in 50 SoG) you've so far read, do you want to see get film adapted, as you reckon it's far superior.
Please elaborate on why it made for compelling reading and compelling viewing, if it was either film adapted, or premium cable TV series adapted.
