The film lacks LGBTQ+ characters or non-heteronormative identities. Interpersonal dynamics focus entirely on traditional romantic and familial structures.

Female characters largely occupy domestic or reactive roles typical of 1950s melodrama. While the protagonist initiates the plot, her agency is limited by social expectations and the supernatural threat.

The film features a predominantly Mexican cast and setting, providing ethnic authenticity. It avoids the whitewashing common in Hollywood films of the same era by centering a non-Anglo-Saxon landscape.

The story explores the friction between religious superstition and scientific rationalism. However, it functions within a classical morality framework rather than critiquing systemic power or institutions.

There is no nuanced portrayal of physical or neurodivergent disabilities. The undead elements serve as supernatural plot devices rather than explorations of lived experience.
