Bosch: Legacy is set to return for its third and final season on March 27, but the excitement has been overshadowed by Amazon’s abrupt cancellation of the series over six months ago. Now, the show's leading man, Titus Welliver, has thrown his full support behind the Save Bosch: Legacy petition, which has been gaining momentum as fans demand a proper ending for Harry Bosch, and who could blame them? Welliver outright supporting the petition is a big step for those involved in it, and with nearly 30,000 signatures so far, at least Amazon know fans aren't thrilled about the decision to axe the show.
