It’s interesting. My mother-in-law isn’t what I’d call prudish, but she definitely restricted what her children could watch in terms of things like R-rated movies.
My father, on the other hand, was a film historian who, despite that, didn’t really understand what movies were and were not appropriate for kids, which is why I saw Aliens in the theater when I was 9 years old.
We spent a long time butting heads over how far I wanted to go with my own daughter in terms of age appropriateness vs. how far she wanted to go. I eventually won that battle when my daughter turned 12 and my wife realized that there was no way to hide the world of R-rated things from a 12-year-old with YouTube anyway.
And that’s why my daughter’s favorite movie is now Forbidden Zone.
