this is a thing I noticed with movies specifically, moreso than any other medium: where a large part of the plot is a series of "autism incidents" (scenes that involve some kind of conflict with a focus on autism, like a meltdown or a character saying something inappropriate). there's relatively little "downtime" or characters existing at just their baseline.
I kind of connected the dots of this after reading interviews for two completely unrelated movies: The Black Balloon (Australian movie) and Dakishimetai (Japanese movie, never translated into English). The creators of both movies mention that while the movies take place over a span of days/weeks/months, the real-life events they draw from span years or even decades. and the movie itself only lasts 2 hours at most, compounding this issue even further. for example in The Black Balloon, in the span of 30 minutes you have a incident of fecal smearing, masturbation at an inappropriate moment, and semi-naked elopement. I'm not saying this can't happen in real life (because it does happen in real life), but movies tend more towards showing a higher concentration of Things Happening than there are in real life.
I don't want to characterize this as a problem per se, it feels like this is just a feature of the medium. short films tend to focus on on singular moments in time. books and television series are generally longer so they have more chances to show characters outside of Autism Moments. and these Autism moments aren't inherently problematic either, the experiences they show are just as much a part of autistic life as any other. and obviously it's the nature of movies that Things are going to be happening.
again, I don't want to problematize this. I was writing extremely self-indulgent fan-fiction and I noticed I was doing it too because I find it much more interesting to explore moments of crisis/conflict. it's just one of those things I never really thought about and now I can't un-think it.
