A Complete Unknown is a Bob Dylan biopic starring Timothée Chalamet, who delivers a captivating performance praised for its accuracy and emotional depth. While Chalamet’s portrayal and the film’s music are highlights, the screenplay is criticized for its predictability and failure to explore Dylan's life beyond well-known events. Supporting performances by Monica Barbaro as Joan Baez and Boyd Holbrook as Johnny Cash also receive acclaim. Despite a somewhat generic narrative, the film's strong lead performance and musical elements make it a worthwhile watch, potentially appealing to both Dylan enthusiasts and newcomers alike.
