The film lacks prominent LGBTQ+ characters or non-cisnormative identities. The narrative focuses its social structure entirely on biological determinism and genetic caste systems.

Women are depicted in significant professional and intellectual roles within the Gattaca Corporation. Characters like Irene are active, autonomous participants rather than submissive tropes.

The film uses a biological proxy for race through the 'Valid' versus 'In-valid' distinction. This systemic caste system mirrors historical racial hierarchies and the 'othering' of marginalized groups.

The story offers a profound critique of Western institutionalism and the commodification of life by biotechnology. It frames the struggle for individual agency against a soul-crushing, technocratic social order.

Jerome Morrow provides a nuanced portrayal of physical disability. The film avoids 'inspiration porn,' instead exploring the psychological implications of living in a society that views imperfection as failure.
