I hated that film. You want good Pasolini, watch Mama Roma.
I have an extra sealed copy of an older Salo region 2 BFI DVD, a version that at least used to be the definitive version of the film lol. I shippz it to yas if ya wantz itz.
But it makes you REALLY gay if you do want it, cuz that film is utter, utter shit. Served on a plate. Then eaten with a knife and fork.
