This essay proposes “newtro-punk” as a framework for understanding the Korean science fiction film Space Sweepers (2021) and its intervention into speculative fiction’s colonial genealogy. Newtro (Nyut’ŭro), a portmanteau of “new” and “retro,” focuses not nostalgic recreation but critical reinterpretation of past aesthetic forms to recuperate the visual vocabulary of colonial modernity and developmental hardship. Where silkpunk recovers precolonial material cultures, newtro-punk engages the traumatic textures of modernity itself, transforming worn surfaces produced under colonial extraction into speculative resources. Through analysis of the film’s remediation and citational practice, linguistic reappropriation, characterization of marginal subjectivity, and typographic aesthetics, this essay demonstrates how Space Sweepers enacts epistemic reappropriation by way of aesthetics, contesting established frameworks regarding what counts as properly futuristic through strategies that enact alternative valuations rather than merely arguing for them. The newtro-punk wager positions worn textures and vernacular particularity as legitimate materials for imagining futurity, demonstrating that futures imagined from positions of precarity possess validity equal to those imagined from positions of power.
