Loved these last few episodes. The finale airs in January, right?
The ironic thing is that while the series has been a cult hit all along it's taken a while for it to gain the audience share to be a hit by any definition: the show's more popular now than it's ever been, so Hirsch is going out on a real high. I'm sure Disney is a bit chuffed by that, though. No doubt they'd prefer making it's run comparable to Phineas and Ferb now that the ratings are good.
Once the series ends I'd love to have a complete Blu-Ray (hell, even DVD) set so I could watch it all in one go in order and catch all those episodes I missed due to Disney's random scheduling. Disney's typically horrible on that front, but even they seem to realize the show has an older, passionate fanbase, so who knows?
