Scary asylums! Creepy disfigured people! People being punished for ‘not moving on and letting their trauma control them’! Violent and dangerous ‘crazy’ people! Poverty coded scary old women who must be a witch!
While asylums are less common horror locations these days, it still doesn’t stop the genre from using pop psychology to frame itself as deep while simultaneously expousing harmful messages. Usually written by people with very shallow understanding of the themes they’re employing for cheap scares at the expense of some of the most marginalized groups.
Also this might be cringe taste but some horror I actually do like are Jordan Peeles movies, because the themes of those are things like “Wow racism is horrificly dehumanising” and “Animals should be respected.”
One of the reasons I avoid anything with M. Night Shyamalan. Every single movie of his except probably The Sixth Sense (it probably does but I don’t remember) has some advanced level ableism that goes beyond the usual ableism found elsewhere. It’s like he refuses to talk to any people who are disabled or the experts who treat such conditions.
It’s a problem throughout Hollywood, though. The same nonsense happens with racism, sexism, etc. And when they do make movies about these topics, they still aren’t helpful because of how they still insist on using negative stereotypes. Just look at bullshit like Mississippi Burning or Shallow Hal.
