The film focuses on a stifling heteronormative marriage. While Thérèse shares an intense emotional bond with her sister-in-law, Anne, there is no explicit depiction of same-sex intimacy or non-cisnormative identities.

Thérèse subverts traditional gender hierarchies by resisting patriarchal structures. Rather than a submissive wife, she is a woman defined by her psychological rebellion against a stagnant, property-obsessed husband.

The setting reflects the demographic homogeneity of early 20th-century provincial France. The cast is predominantly white, mirroring the social realities of the French bourgeoisie during this era.

The narrative critiques the sanctity of the nuclear family and rigid social codes. It portrays the preservation of family names and property as oppressive forces that dictate individual morality.

There are no prominent depictions of physical or neurodivergent disabilities. The story remains centered on the psychological and social tensions between the primary characters.
