Simple solution - rate violent films X.
Why not? Ok, I get the huge argument about free speech. We can't be stifling 'creativity' by limiting the gore and gratuitous violence we allow to be shown on the screen. The board of censors is gone.
But penises? Oh my god we can't have that on the screen! Boobs are fine though. As long as there's no babies nursing shown. Is there any logic to this? Whatever that logic is, somebody somewhere slaps an R or X rating on a film. Too pornographic, it's all about sex.
And words. Sticks and stones no one cares about but in Hollywood, words can hurt you. Too many bad words gets a film PG 13 or R rating. Is it M these days? I forget.
But violence? No problem at all. Show any amount of murders, mutilations, blood, implied rape. And I think nearly all male characters are considered wimpy unless they punch someone. Physical fighting is de rigeur at the movies. (But boys don't try anything you see on screen at home because your school has a zero tolerance policy - as in, zero tolerance for your gender.)
A simple remedy for hyper-violent films - apply an X rating. Sure go see it but you acknowledge that you know you're going to see gratuitous gore. Wonder why the studios have been fighting this idea for so long?
