Reacher Season 2 has been getting rave reviews, with five episodes so far available to stream on Prime Video, with another three to come leading up to the finale on January 19. Alan Ritchson plays the eponymous hero, Jack Reacher in the sophomore run, and he is surrounded by a very good ensemble cast of characters from his former unit. Serinda Swan joins season 2 as a series regular, portraying Karla Dixon.
