I really dislike movie ratings in general. I watched a ton of 18+ and R rated films as a kid and think I turned out just fine.

On the other hand a few kids I grew up with that had helicopter parents and weren’t allowed to watch some Disney movies because they thought it was too harmful ended up very… Damaged. Like they can’t moderate themselves and decide what is too much for them, have nightmares at the smallest little things, can’t separate out fantasy from reality in some cases, etc.
