Losing a main character can be the beginning of the end for a TV show. Audiences get attached to familiar faces, chemistry takes years to develop, and replacing someone who helped define a series is rarely easy. Every once in a while, though, a major departure forces writers to shake things up in exactly the way a show needs. New characters arrive, tired dynamics disappear, and storylines suddenly have room to move in directions that weren’t possible before. In a few particularly surprising cases, the seasons that followed became some of the most beloved parts of the entire series. These shows proved that losing an important character doesn’t always mean losing the audience. Here are 15 shows that lost a main character and somehow got better.©IMDbParks and Recreation, Mark BrendanawiczMark was part of the core cast for the first two seasons, but his relatively grounded personality increasingly felt out of place as the show embraced its stranger side. His departure coincided with the arrival of Ben Wyatt and Chris Traeger, helping launch the era when Parks and Recreation really found its identity.©IMDbCheers, Diane ChambersDiane’s relationship with Sam defined the first five seasons, so Shelley Long’s departure could easily have wrecked the show. Instead, Rebecca Howe brought a completely different dynamic to the bar and allowed Cheers to lean further into its ensemble comedy.©RedditNYPD Blue, John KellyDavid Caruso left after barely more than a season despite being one of the show’s original leads. Jimmy Smits arrived as Bobby Simone, whose partnership with Andy Sipowicz became one of NYPD Blue’s defining relationships and helped the drama flourish without Kelly.©IMDbAngel, DoyleDoyle’s departure only nine episodes into Angel left a surprisingly large hole in its original trio. Bringing Wesley into the group and passing Doyle’s visions to Cordelia ultimately created new dynamics that would carry the series far beyond its early monster-of-the-week setup.©IMDbMAS*H, Henry Blake and Trapper JohnMAS*H lost both McLean Stevenson and Wayne Rogers after Season 3, then introduced Colonel Potter and B.J. Hunnicutt. Rather than recreating the departing characters, the replacements brought completely different personalities and helped the series develop into a richer blend of comedy and drama.©IMDbDoctor Who, The First DoctorWilliam Hartnell leaving should logically have ended a show built around one mysterious time traveler. Instead, the Doctor regenerated into Patrick Troughton, establishing the brilliant storytelling device that has allowed Doctor Who to reinvent its protagonist for generations.©IMDbHomeland, Nicholas BrodyBrody was so central to Homeland that the original premise seemed inseparable from him. Once his story ended, however, the series was free to expand beyond the Carrie-Brody relationship and reinvent itself as a globe-trotting espionage thriller.©IMDbThe Good Wife, Will GardnerWill’s shocking exit in Season 5 destroyed one of the show’s most important personal and professional relationships. It also forced Alicia into unfamiliar territory, giving The Good Wife an opportunity to reshape her story instead of endlessly returning to the same romantic question.©RedditFriday Night Lights, Jason Street and Smash WilliamsFriday Night Lights gradually allowed its original high school players to graduate and move on rather than keeping everyone in Dillon forever. The transition eventually gave us East Dillon, a new team, and a collection of characters who helped make the final two seasons some of the show’s strongest.©IMDbMisfits, Nathan YoungRobert Sheehan’s Nathan was such a huge part of Misfits’ early appeal that losing him seemed nearly impossible to overcome. Rudy arrived with an entirely different personality and eventually became central to a new version of the group rather than simply trying to imitate Nathan.©IMDbCSI, Gil GrissomWilliam Petersen’s Grissom was the calm center of CSI for most of its first nine seasons. His departure forced the procedural to rely more heavily on its ensemble and introduce new leadership, allowing the series to keep evolving instead of remaining permanently built around one investigator.©IMDbER, Doug RossGeorge Clooney had become one of ER’s biggest stars by the time Doug left County General, but the hospital was always bigger than any single doctor. His exit created more room for other characters and helped prove the show’s revolving-door ensemble could sustain entirely new generations of stories.©RedditLegends of Tomorrow, Hawkman and HawkgirlThe Hawks and their battle with Vandal Savage drove much of Legends of Tomorrow’s first season, but that mythology also kept the show tied to a fairly rigid mission. Once they were gone, Legends embraced time-travel absurdity, bizarre adventures, and the chaotic ensemble energy that became its real personality.©IMDbTaxi, Bobby WheelerJeff Conaway’s Bobby began as one of Taxi’s central young characters, but the ensemble had much stronger personalities waiting for more screen time. After his departure, characters played by Danny DeVito and Christopher Lloyd became increasingly important to the show’s distinctive comedy.©IMDbThe Hogan Family, Valerie HoganThis one managed something few shows could survive: losing the character whose actress originally gave the series its title. After Valerie Harper’s departure, Sandy Duncan joined as the boys’ aunt, the show was eventually renamed The Hogan Family, and the reworked version continued for several more seasons.The post 15 Shows That Lost a Main Character and Somehow Got Better appeared first on Den of Geek.
