Getting attached to characters in shows like Game of Thrones or The Walking Dead is a risk, because those series kill off major players like it's their job. But on most other shows, it's surprising and strange when the staff writes off a character that was integral to the narrative. Sometimes actors decided they'd had enough of whatever irked them on set, and asked to be put out of their misery; at other times it was the executives who wanted to try something new.
Many of these shows soldiered on without popular characters with mixed results. Sometimes the show changed networks entirely; sometimes they squandered all the good will they had built up over the seasons in just a handful of episodes. Of course, there are cases where the series only improved after the departure of a central star.
Some of the biggest comedies and dramas of all time went through a startling departure, from ER and The X-Files to The Office and Cheers. Imagine the episodes that might have been.
That '70s Show ran on Fox for eight seasons, focusing on the lives of a group of high school friends in the 1970s. The cast was impressive, featuring Topher Grace, Ashton Kutcher, Mila Kunis, Laura Prepon, and more. The show started out covering important social topics of the 1970s, including the recession, changing sexual attitudes, and underage drinking and drug abuse. Ultimately, the showrunners moved the narrative more towards the dynamics of the group itself and away from the time period in which it was set.
Grace, the face of That '70s Show, left after Season 7 to pursue a film career; rumors suggest he didn't get along with his castmates either. Kutcher scaled back his involvement around the same time. The show was completely reworked around the remaining cast members, but only survived one more season before Fox decided it was time to pull the plug.

The American version of The Office was a huge hit for NBC. Over nine seasons, the mockumentary-style show followed the daily life of the employees of the Dunder Mifflin paper company. It was a true ensemble, but the heart of the sitcom was definitely Regional Manager Michael Scott (Steve Carell).
Carell left The Office after Season 7, and it nearly killed the show. They gave Andy Bernard (Ed Helms) the manager's job, but immediately lost track of what made him unique. New characters were non-starters, and the writing devolved into zany gags and absurd caricatures. By the time The Office limped to its finale, even diehard fans were glad to see it go.

The X-Files was a sci-fi drama about FBI agents investigating the supernatural that originally ran on Fox for nine seasons in the '90s and early 2000s. Viewers tuned in partly for the chemistry between believer Fox Mulder (David Duchovny) and skeptic Dana Scully (Gillian Anderson). Their relationship was developed slowly over the course of the series, from grudging partnership to close friendship to full-blown romance.
That's why it was a pretty big blow to the show when Mulder was abducted by aliens at the end of the seventh season. Worse yet, it all happened because of a money dispute between Duchovny and 20th Century Fox. The showrunners created a new character named John Doggett (Robert Patrick) to fill the void, but the magic was gone. The show mercifully ended shortly after Mulder said goodbye. When The X-Files came back in 2016, though, Duchovny was back on board.

Two and a Half Men ran for an incredible 12 seasons on CBS. It followed single dad Alan (Jon Cryer) and his boozehound bachelor brother Charlie (Charlie Sheen), along with Alan's son Jake (Angus T. Jones). The show was very successful, thanks in large part to the odd-couple comedy of Alan and Charlie – until Sheen decided to go on an insane rant about his boss Chuck Lorre.
That was the end of the fictional Charlie. The writers unceremoniously killed off his character (his body exploded like a balloon full of meat), and the show added Ashton Kutcher as Internet tycoon Walden Schmidt to fill the void. Two and a Half Men continued on for another three seasons. When the series finally wrapped, a body double was brought on to replace Sheen, and a piano was dropped on his head.
