In a world where The Human Centipede 2 exists, we are already far over the callous insensitive violence line.
Human Centipede is honestly nothing compared to the mounds and mounds and heaping, quivering, exploitative mounds of crap still archived on film.
Classics such as "I Spit On Your Grave", wherein the victim of a brutal gang rape murders all her rapists, one by one.
Or "Cannibal Holocaust", the spiritual ancestor of every 'horror film that is pretending to be a documentary' ever, which also features live animals dismembered on camera and such horrific gore special effects, filmmaker Deodato was arrested and tried for multiple obscenities and cruelty to animals in Italy.
Or "Gigli," ninety fucking minutes of J-Lo and Ben Affleck bantering back and forth in accents so horrifyingly grating you will wish you were a victim in Cannibal Holocaust, getting your intestines pulled out and eaten.
Let's go back a lot further: Shakespeare's "Titus Andronicus" features the eponymous lead's daughter brutally raped and then her eyes, tongue and hands are mangled and removed.
"Oedipus Rex" has a man murdering a man he does not know is his father and then marrying a woman he does not know is his mother. When he learns the truth, he puts out his own eyes and wanders out into the world, with the aqueous and vitreous humors of his fucking eyeballs 'bedewed in his beard'.
Egyptian God Osiris is betrayed, murdered and torn to pieces. Isis tries to find all his parts, but a fish has eaten his penis. So she makes him a new one out of wood, and he is restored to life. They then fuck.
Humanity's insensitivity to violence, as a whole, is
not especially new.
