The substance (2024)
The movie is not scary nor realistic. It's rather schematic and conventional, like a fable.
1. The most obvious interpretation is about female's fear of aging. Heroine's TV career is tied to her appearance which makes hitting the wall for her especially painful. But in out times every woman desperately tries to look young in 50-s because:
1.1. Modern culture is teenager's culture. As Dugin puts it, modern society is sick with hebephrenia.

Women can spend hours working on their beauty, for them ugliness depicted in the movie is especially painful.
2. But for me the first thing I thought of are BOOMERS and conflict of generations. Be heroine normal person, she would just retire and let the next generation shake their asses on TV. But individualism which became dominant in post-WWII West makes that impossible - boomers don't view their children as continuation of themselves, can't self-realize in their children's lives. They will rather buy a villa abroad than help their children with mortgage, and children pay them back with bad attitude. But as the voice in the phone says, "there is no you and them, you are the one", society can't survive inter-generational total war.
Since you can't take millions with you to the afterlife and Christian God is antagonistic to the Golden Calf, boomers believe in techno-singularity. When they'll start dying en masse, seeing that AI-neurogod hasn't arrived to save them, they'll act insane. Their dysfunctional offspring will be even worse. That's what the final scene shows. God help humanity survive those times.
3. There is a group of people IRL who have unrealistic desires, resort to radical measures in a groundless hope to achieve them and as a result turn into abominations.
Happy trans awareness month!To sum up, deeply antiliberal movie, which really makes you think
