Undone travels well-trod territory, with a multi-layered, multi-timeline story told through the eyes of a lead character who is either mentally unwell or, in fact, gifted. But two things set the series apart from all previous TV mindfucks: the brilliant use of rotoscope animation, and the acerbic, vulnerable lead performance of Rosa Salazar (offering her second brilliant performance of 2019 which is hidden behind layers of computer animation). The chemistry of an excellent cast (including Bob Odenkirk) reveals the animation as not just a storytelling gimmick, but as the only proper way to tell this splintered and compelling narrative.
