Bosch: Legacy is bowing out after three seasons, but fans are fighting to save it with a petition on change.org. News of the petition has spread to Michael Connelly, the author of the books and one of the executive producers on Bosch: Legacy, and he was supportive of the fans' efforts to save the show. Connelly also recently opened up in an interview about the Jerry Edgar spin-off, which was axed soon after Legacy's cancelation. He said he was still upbeat it could happen if the upcoming spin-off Ballard does well.
