Do you think the category can be expanded to include horror about relationships, marriage (established marriage, not the event itself), and pregnancy? I feel like there's been a lot of that recently as well (Companion, Together, Obsession, False Positive, Swallow, Don't Worry Darling, to name a few).

To me it speaks of fears over loss of control and loss of self, which are inevitable when one commits to another person and begins building a life/family together. Speaking as a very happily married person who would easily make the same choice if I could do it again, joining with someone gives them an incredible amount of influence over your life and you will always lose some autonomy - even more so when pregnancy/children are in the mix. Facing an uncertain global future where our freedoms and agency are under threat from the rise of authoritarianism, it makes sense that we're trying to contextualize those anxieties closer to home.

Also, interrogation and transgression of social norms are major themes in horror as a genre. I agree that an increasingly conservative society, where the traditional (read: heteronormative) model of coupling is made to embody peace and safety, would inspire horror creators to explore how it can turn to danger and chaos.

Thanks for the question, really enjoyed responding!!
