The good news with all of the series finales for Futurama is eventually you can hit your personal finale

For me it's the fractal of them zooming in and out of the simulations, and slowing down a simulation so far that it feels like to the people observing the simulation that the simulation has stopped, however for the people in the simulation it feels as if their timeline is running exactly the same as always. Everyone's sad to see it end, but Fry and Leela recognize instantly that for the people within the simulation that the stories never end.

IMO it was the perfect ending and I refuse on rewatch to watch past that

Futurama hasn't declined anywhere near as badly.

Simpsons hasn't been canceled nearly the same number of times. Futurama is the zombie that won't stay down.
