Wow !! I thoroughly enjoyed that ! Factual,no-holds-barred documentary making at its very best.Stunning realism,and a pleasingly down-to-earth approach to the sometimes seemingly insuperable problems attendant upon an understanding of what really drives men to participate in this ridiculous and depraved activity.I thought the item at the end,about shagging a pig,was most poignant.Whoever made this ground-breaking film-----I salute you!!
