Science fiction frequently critiques systems that organise life through prediction and control, yet such critique does not always culminate in structural transformation. This article examines the film Gattaca (1997) as a narrative that exposes the ethical limitations of genetic determinism while simultaneously containing that critique through its resolution. The film reveals how futures are allocated through biological prediction, misrecognising human capacity and foreclosing opportunity, yet ultimately resolves ethical disturbance at the level of individual exception rather than institutional change. Drawing on Frank Kermode’s account of narrative endings and concordance, the article argues that Gattaca achieves ethical closure by aligning aspiration with achievement and rendering injustice intelligible without demanding structural revision. In doing so, the film stabilises a designed future by rendering ethical critique legible rather than transformative.
