oh kids still sneak in. before the 90s, most theatres were single or double theatres ,so kids would sneak in the fire door and duck when the usher came by.
Then the multiplexes came.
Now they pay to see a G or PG movie, and switch theatres in the multiplexes, ducking as they go… and I’m sure there’s still some that do the fire-escape trick still.
potty humor, sexual innuendo – it’s all right at 4th grade humor, although I think a lot of the innuendo will go over their heads for now.
I think that’s why the rating system respects that in a way: R rated means “no child without adult”. ie – it’s not rated X (or whatever they call it now).
So, it’s up to the adult.
