The prequel series Grease: Rise of the Pink Ladies has been charged with '50s era inconsistencies that disregard the prominent creative liberties made in the 1978 film, Grease. Although Rise of the Pink Ladies holds some magical appeal as a modern musical television series set to imagine the origin of the famous girl crew, it faces a fair amount of backlash for its depiction of the nostalgic 1950s period that inspired the legacy of Rydell High and its students. Taking place four years before the events of Grease, the prequel observes four young ladies as they carve their own narratives through a more conservative generation.
