I saw loads of movies when I was really young.
Sitting in the living room playing lego or whatever toys, whilst aliens, terminator, rambo or whatever were on the TV being watched by the rest of the family.
Never did me any harm.
I'm not sure how old I was but I was born in 1981 so probably about 6-8 when most of these films were on VHS, weren't we all watching WWF as a family back then too, seeing blokes getting beaten up all the time.
Never phased me, and I don't remember nay kids in the street wanting to do play wrestling where anyone got hurt.
movies don't ruin your concentration span, unlike thicktok and emptytube 2-3minute videos some people let their kids watch for hours on end.
