читать дальшеG: General audience. Nothing you couldn't say or do in front of a
roomful of preschoolers and your grandmother.
"Oh look, James bopped that nasty pirate on the head again! Now, he's
going to give Elizabeth a peck on the cheek!"
PG: Mild violence. Vague allusions to sexuality and sexual
attraction. Go subtext!
"James kicked the pirate in the stomach, sending him overboard to the
sound of a mighty splash! Enthralled, Elizabeth leapt into James'
strong arms and they kissed without tongues."
PG-13: Moderate violence, but still no really detailed gory
descriptions. More detailed allusions to sexuality and sexual
attraction, but nothing unclothed below the belt.
"James pulled out his pistol and shot the pirate through the heart.
As the pirate collapsed to the deck, James strode up to Elizabeth and
kissed her passionately. Mad with desire, they began to explore each
other's clothed bodies with their hands as the camera faded to black."
R: Horror movie gore, sexuality and nudity, but nothing overtly explicit.
"James drew his sword and ran the pirate through the heart. As the
man's lifeblood spurted everywhere, James cut off his head and put the
decapitated skull on a pike. Elizabeth ran up to him, ripped his
clothes off, and they proceeded to [BLEEP] like mad, sex-crazed monkeys
on the deck."
(Obviously, you don't need to bleep out obscenities, if it has an R rating. I just had to keep the profile clean.)
NC-17: Anything goes.
If I have to explain what James and Elizabeth do here, then I weep for
the Internet.
