Theoretically, Bridgerton will conclude after eight seasons, since that is how many books are in the series, but it can (and should) reduce that number to six. The Netflix show is an adaptation of Julia Quinn's book series of the same name. Each novel chronicles one of the eight Bridgerton siblings' love stories, and every season does the same. The show began by adapting Daphne's romance, followed by Anthony's in season 2, and Colin's in season 3. Benedict's love story is next in season 4, meaning four siblings are still waiting for their time in the spotlight, but that time shouldn't come for two characters.
