The film focuses on romantic entanglements that adhere to the heteronormative structures typical of 1948 cinema. There is no evidence of non-cisnormative identities or any disruption of traditional sexual norms.

The narrative centers on a male physician's discovery of a female mermaid. While she shows agency by requesting a trip to London, she primarily serves as a romantic catalyst for the male protagonist.

The film likely reflects the homogeneous casting standards of the post-war British film industry. The setting and era suggest a narrative architecture rooted in Western-centric, Anglo-Saxon norms.

The story uses fantasy to celebrate Western urbanity through a journey to London. It reinforces traditional social structures rather than offering any critique of Western-centric storytelling.

The film provides no mention of characters navigating physical, sensory, or neurodivergent conditions. No specific characters are identified as having disabilities.
