Bosch: Legacy's final season has four episodes left to go, but Harry Bosch's solo story doesn't feel ready to end yet. Amazon's cancelation of Bosch: Legacy continues to baffle the dedicated fan base, who launched a petition to save the show over six months ago. Titus Welliver has backed the petition, and in a recent interview, he revealed that he remains hopeful that Harry Bosch will be revisited at some point in the future.
