Back in 1968, after the murder of Bobby Kennedy and the anti-violence hysteria that followed, adult TV shows (but safe for children) were dumbed down to kiddie shows. Pulp fiction magazines cleaned up their gritty covers, movies shown on TV were butchered to remove “violence”.
The movie industry got a pass as they said they would regulate themselves with a joke of a ratings code. “G,M,R,X” which killed the Hays Code.
with the Hays code dead, they reshot scenes to add more blood, guts, violence and lots of SEX!
Movies now are just to food to sate the masses, much like old Gladiator fights.
The original Planet of the Apes had nudity, violence, and profanity and it still got a G rating on its original release.
