Some series get cancelled and Cut Short. Other series last far longer than any fan had wanted and become a Franchise Zombie. But some series decide to end the show on their own terms, long before the network decides to cancel them and before the fans begin to tire of them. This is not simply the last season of a series or a celebration of a series that ends before it can become a Franchise Zombie. The defining characteristic of The Final Season is that it is a planned final season and is announced as such from the very beginning. The Final Season will work to tie up any loose ends and answer any unanswered questions. During the Final Season, the writers may feel the freedom to tackle themes and stories they would otherwise not attempt, and to upset the Status Quo so much, they risk Jumping the Shark. Think of it as a Grand Finale, but stretched across an entire season. This is an Ending Trope, so expect unmarked spoilers.
