Brooklyn 99 can still continue via a new spin-off that will follow a particular character — Captain Raymond Holt. A couple of years since Fox's original cancelation of the cop-centric sitcom, NBC also pulled the plug on the project, resulting in its official ending in 2021. Since the show's end was pre-planned, Brooklyn 99's producers and writers were able to craft a perfect send-off to 99tth Precinct as many of its members go through life changes which marked the end of an era for the squad. Despite this, however, the comedy could still move forward, but this time, through a prequel story.
