Deciding when to end a TV show is incredibly tricky: rush things and you can end up with a Game of Thrones-level catastrophe, but let it drag on for years longer than the story "needs" and you get something like Dexter's depressing original run.
And so, while fans will usually be sad to see their favourite shows go regardless, these 10 TV series feel like they're getting an ending that's been one hell of a long time coming indeed.
Regardless of the state these shows are currently in, fans have largely been expecting them to wrap up for quite some time, and whatever the reason - most often network greed or production delays - they're still going.
But the end is finally, finally nigh, with each of these shows having either outright announced an upcoming end-point or at least blatantly signalling that it's on the very near horizon.
On one hand these shows coming to an end will leave a bit of an empty void in fans' hearts, but on the other, you can't deny that they've had a damn good run all the same...
10. The Walking Dead
It's often repeated among The Walking Dead's long-suffering fans that the show itself has become a shambling zombie that simply refuses to die, but after 11 seasons, it will finally air its last-ever episode on November 20.
Even though many have dubbed the last few seasons a fair return to form, The Walking Dead is a show that clearly just... kept going far beyond its actual creative threshold because the ratings remained relatively high.
But when protagonist Rick Grimes (Andrew Lincoln) departed the show mid-way through 2018's season nine, the ratings entered a seemingly irreversible death spiral, with a recent episode garnering an all-time low of just 1.55 million viewers, compared to its all-time high of 17.29 million for the season five premiere.
Though AMC already has numerous spin-off projects in the works - one centered around Daryl (Norman Reedus) and Carol (Melissa McBride), another around Rick and Michonne (Danai Gurira), and one focused on Maggie (Lauren Cohan) and Negan (Jeffrey Dean Morgan) - it'll nevertheless be a relief to see the flagship show finally put out to pasture, many years after it reached both its narrative and ratings peak.
