I talked about this on Mastodon a while ago but I'm saying it here again. If you're autistic and you haven't watched any of Yorgos Lanthimos's movies you're absolutely missing out. The dude is an unhinged freak (compliment) and all of his movies are about how utterly average, unquestioned social norms are actually the stuff of nightmares. If you're autistic and social norms are already the stuff of nightmares all his movies will make perfect sense.
Some recommendations:
The Lobster - Heteronormative dating culture is very healthy and completely reasonable. Also if you're single for too long you get turned into an animal and sent off into the woods.
Dogtooth - Your parents love you, and just want to raise you right, which is why they sometimes do things that seem like they might violate the Geneva convention.
The Killing Of A Sacred Deer - The social pressures of being a white collar, picture perfect suburban family are not at all excessive or deranged. Sometimes you just gotta chain a teenage boy up to a pipe in your basement for normal family reasons.
Nimic - Ever felt like someone trying to talk to you on public transit was the most invasive possible thing a human being could do? Well....
