This study delves into the unique qualities that make Korean SF stand out and explores the shortcomings of American productions. By examining the complex themes, stunning visuals, and intricate narratives of selected Korean SF films and web series, this study aims to provide a comprehensive analysis of the genre’s current state. My study also highlights the need for a re-evaluation of the traditional formulaic approach to American science fiction and a renewed focus on creative storytelling and thought-provoking concepts. Therefore, through this paper I tried to critically analyze Korean Science Fiction (SF) films and web series from the last decade like Hellbound (2021), Monstrous (2022), Kingdom (2019), Train to Busan (2016), The Host (2006) to keep the study specifically contemporary and relevant, examining their superior plots and how they differ from Western SF films and Web Series. A comparative study is conducted between films and web series in South Korea and America, while trying to answer certain questions linked with the success of South Korean SF films and web series regarding their declining stage of American SF. Moreover, the analysis offers insights into gender and sexuality issues and the influence of neoliberalism in Korean SF. The importance of cultural specificity and originality in SF storytelling is also taken into consideration, adding valuable contribution to the field of SF studies. I’ve based my paper on theories like the reception theory, which allows me to analyze how the audience interprets and engages with literary and media texts which eventually leads me to study reasons behind the success of Korean SF. I’ve also considered the Narrative theory, the Genre theory along with certain generic understandings of cultural studies and postmodernism. The paper uses thematic and cultural analytical processes as its methodology for which the focus throughout, remains highly ideological and at the same time, tries to consider how a story relates to the society and culture from where it originates.
