+1 Thunderbolt and Lightfoot. (Sadly) I saw it whilst still a kid and it messed with my head.
Another recent (for me) one that really got to me was ‘Sin Nombre’. I thought the subject matter would be far away from me as can be but the film reminded sharply of my young desire to escape from the weirdness and often violent undercurrent of (macho) adolescent peer pressure*
*Albeit on another level ie they used guns with bullets and actually killed each other, whilst in polite England I was simply robbed, beaten and shot with an airgun. A boy in a neighbouring comprehensive school was stabbed to death but that was an anomalous occurrence in our neck of the woods.
I think the overwhelming feeling I got from Sin Nombre was the sometimes hopelessness of young people who wish to escape the peer culture they were born/thrown into. It’s like escaping from glue, where the merest effort to extricate makes it stickier still!
