When Galaxy Quest: The Journey Continues inevitably films its last episode, Alex practically throws a fit, but not for the reasons that made up the totally unofficial betting pool.
Gwen, at one point, says that the show really couldn't have gone on; they'd run out of stories worth telling, and seven years is a good run. "And anyway, we blew up Earth. And the ship."
"But that's the POINT," Alex yells. "What will they THINK? Mathesar, I mean, and the others. Who are so bloody LITERAL."
"...shit," Gwen says.
(The reboot, years later, changes the ending to an alternate universes.)
