I loved the movie as a kid. First saw it when I was about 11. My school never had cliques like the ones averred to in TBC, but I could still recognised the individuals in the film. I can still see them now, as a teacher.
These days I’m slightly more sympathetic to Vernon, the teacher, in some ways, but less in others. (I rewatched the film a couple of years ago).
How would the kids have changed after this experience? Well, change doesn’t always have to be immediate. Quite often, someone will admit they’re wrong about something but take a long time to actually change their behaviour because of it.
OTOH, there was sex involved, and that’s a bloody big motivation when you’re 17 years old (guess at their ages).
Andy and Allison might well have got together at least for a while. Yeah, he probably liked her more at the end because she was pretty, but also because, as he said, ‘I can see your face.’ He wasn’t focusing on the clothes or the hairstyle per se, but on the fact that he could see her face. Not that shallow for a teenage boy, really.
His father probably wouldn’t have been that bothered, unless it meant that Andy spent less time training. Alison could have turned into a hopelessly needy GF who took him away from his training, or she could have been perfect for him - so unused to attention that she let him train as much as he wanted. It didn’t seem like he hated wrestling, only the pressure.
For the rest, the changes would have come about a year or two or even more later. Hell, even just saying ‘hi’ in the corridors would have been a change, from the sounds of it. You can’t underestimate the impact of small changes in behaviour - like distracting your friends who are intent on teasing the smart kid, even if you can’t bring yourself to say ‘he’s my friend’ due to one morning in detention together.
Maybe I’m alone in this, but I liked ALL of the characters in TBC. As a kid I watched it repeatedly and tried to fit myself into the jock, the princess etc moulds. Alison’s character fitted me best, or perhaps Brian’s, with a definite dose of Bender, but I wasn’t exactly far away from the others either.
An aside: in British English, Bender means ‘gay person’ (usually male). The first time I heard his name called in the film I thought he was being derided. Later in the the film, I realised it was just a name, but it still grated on me every time it was said.
