Another thing that's been nagging me about the finale;
I get why Lisa Kudrow et. al would be so bored with the stale Good Place, seeing as no one new had entered in millennia. But once the doors opened up thanks to Team Cockroach, wasn't the novelty of new people worth something? Shouldn't that keep things interesting for as long as new people keep getting in?
And for Team Cockroach, after fighting Judge Gen so hard to not reboot the universe, after they win, they... just didn't care to see what happens with humanity? There was no desire to hang out for tens of thousands of years just to see what the humans got up to? If we ever invent time travel or spaceships that leave the solar system? If we ever solve war, famine or racism? No care at all? No desire to hang around and see if their system continues to work once morality on Earth changes? No interest in seeing where evolution takes the species?
Maybe it's because no one on Team Cockroach had children. I'm surprised Schur didn't consider seeing he has kids... what it would be like to watch all your descendants and what becomes of the world they left behind. (I'm reminded of what Spielberg said about the ending of "Close Encounters", having Richard Dreyfuss leave his family to board the UFO came from childless Speilberg. Once he had kids, he regretted that ending, since he couldn't believe he'd make that choice.)
I would get it, once we reach the Eventual Heat Death of the Universe (and the end of Maximum Derek!), and there were no more people to save, yeah, maybe things get boring after a few dozen thousand bearimys of that. (If you even buy into bearimys, but since Time is a dimension of this physical universe and doesn't necessarily even exist in the afterlife, I'm having a conflict over exactly what that is... my personal beliefs on that are different than the show's, in some ways.)
But my curiosity to see if we ever make Star Trek the Next Generation real would keep me hanging on for much longer than Team Cockroach seemed to care about what they left behind and worked so hard to save.
