Jurassic Park for me. I had an amazing JP jumper when I was like...maybe 6. It was far too big for me but I loved dinosaurs. Naturally this meant I wanted to watch the film because...well I'm 6 and it's got dinosaurs.
Ultimately I ended up watching it with my Mum and Dad. We got as far as the iconic T-Rex chase scene and I told them to turn it off. Didn't go near the film for another few years.
I've now got my own 6 year old. There's no scenario I could envisage where I even consider letting her watch a film as gory, tense and frightening as JP.
Some children’s movies of this era liked to weave hallucinogenically dark themes into otherwise whimsical stories. Many of them played on common childhood guilt or fear of rejection, abandonment, and loss, used merely as props or dealt with in deeply problematic ways.
I will say though they can be great for tripping and/or to lambast with a peanut gallery of friends.
