Hi Deedlet,
I'm surprised your son was able to handle this movie Jaw Drop as the recommended age is 17+. If I saw this movie when I was 14, I think I would have had nightmares for months.
Well, he has been exposed to as much through my words with him. I try to share with him the potential hardships that are possible. I'm more concerned with giving him a glimpse of reality than I am with General movie rating systems (or whatever it is called). I mat not be able to offer feedback in reply to your concern, as it is a rather tricky situation. The point I was trying to make with him is neither he nor I have ever seen hard times. The movie depicts some pretty hard times and so I thought that would give him an incentive to get through situations that might seem difficult. Compared to the movie - little is very difficult these days.
Does that make sense? BTW, there was adult supervision around (my wife, not me

).
Edit: I'm not sure what your age is or if you can get into his shoes. He has certainly not had an easy life and been exposed to a lot of things. Some has been traumatic.
From my perspective sharing it might have provided a jolt for the positive. And if it does depict a possible future reality - foresight might offer a way to forearm(?). This was at least what was going on in my mind and what I told him before we watched.
