The triumphant final season of Star Trek: Picard is finally available for fans to own on DVD or Blu-ray, but The Complete Series feels more "complete" than the disparate stories may suggest. Each season was a unique narrative and visual experience more akin to a movie series than a television show. While the journey Jean-Luc Picard takes is the obvious focus of the show, watching the complete series highlights why each season needed to include the Borg. Beyond being Picard's greatest enemy, it tells an important story about how Gene Roddenberry's ideal future dealt with the aftermath of such a destructive force.
