15. ‘Family Matters’ (1989-1998)

‘Family Matters’ began as a family sitcom centered on the Winslows, with Carl Winslow as the grounded patriarch. The show’s early episodes focused on his life as a Chicago cop navigating family challenges.

10. ‘The Vampire Diaries’ (2009-2017)

Elena Gilbert (Nina Dobrev) drives this supernatural drama’s early seasons, but her exit in Season 6 shifts focus to the Salvatore brothers and ensemble. The show leans harder into action and lore.

Emma Swan (Jennifer Morrison) anchors this fairy-tale mashup, but her departure in Season 7 pivots to a grown-up Henry (Andrew J. West). The reboot-style season explores new stories.

Rachel Berry (Lea Michele) is the glee club’s star, but later seasons spotlight new students like Marley (Melissa Benoist). The focus on younger talent refreshes the music and drama.

The pivot diluted Rachel’s dominance, letting others shine. It kept the show’s heart and songs vibrant despite early stumbles.

7. ‘Misfits’ (2009-2013)

Nathan (Robert Sheehan) leads this quirky superhero series, but his Season 2 exit shifts to new misfits like Rudy (Joseph Gilgun). The raunchy humor and powers evolve.

Nathan’s wit was iconic, but Rudy’s chaotic energy fit the show’s wild vibe. It stayed fresh and bold with the change.

Rick Grimes (Andrew Lincoln) drives this zombie epic, but his Season 9 departure hands the reins to Daryl (Norman Reedus) and others. The ensemble steps up with new stakes.

5. ‘Community’ (2009-2015)

Jeff Winger (Joel McHale) leads Greendale’s study group, but Troy (Donald Glover) and others take center stage after his Season 4 arc softens. The ensemble’s quirks shine brighter.

Jeff’s shift to mentor opened room for wilder comedy. Troy’s growth and group chaos made later seasons hilariously inventive.

4. ‘Buffy the Vampire Slayer’ (1997-2003)

Buffy Summers (Sarah Michelle Gellar) is the slayer, but Spike (James Marsters) evolves from villain to co-lead by Season 4. His complex arc adds emotional weight.
