This study presents a corpus-based analysis of 51 critic reviews of the romantic comedy "While You Were Sleeping", sourced from RottenTomatoes, to explore the linguistic nuances, thematic focuses, and sentiment orientation in film criticism. Employing corpus linguistics and critical discourse analysis, the study systematically examines the language and thematic patterns in these reviews, aiming to understand the broader dialogue about cinema and its cultural impact. The analysis reveals several key themes: the balance between charm and credibility, the significance of lead performances, narrative plausibility versus genre conventions, cultural and seasonal context, divergent perspectives on humor and tone, the importance of cinematic style and directorial choices, reflections on the romantic comedy genre, and audience engagement and emotional resonance. These findings highlight the complex and multifaceted nature of film criticism, particularly in the romantic comedy genre, where films are evaluated not just for entertainment but also for narrative structure, character development, and adherence to genre norms. The study underscores the importance of external factors such as cultural context and timing in film reception and emphasizes the impact of lead performances and casting decisions on audience engagement and film perception. It contributes to a deeper understanding of film criticism, extending beyond mere entertainment to encompass cultural, narrative, and stylistic considerations. The insights gained can inform future film productions, critiques, and academic discussions in cinema studies.
