PG-13? R? WTF?

The Hunger Games’ PG-13
Seems curious amid the fuss
About what’s fitting for a teen
Like Bully and the f-word cuss,
Which drew an R initially.
It’s now unrated; all should see.

But will they? Movie chains then pick
Which school-age kids can go inside,
Excluding some who need this flick.
An unawareness, woe betide,
Of aftermaths of their abuse
Like targets hanging from a noose.

It’s not obscene like Hunger Games
Where youths in order to survive
Must kill each other. Bully shames
In hopes of keeping all alive.
As for the f-word, kids these days
Have heard it used a thousand ways.
