Spoilers, etc., yadda yadda...
I've seen (and participated in) a number of discussions about the Galactica finale. Several people were bothered by the ending, in which the survivors decided on a pretty Luddite existence and chose to drive their ships into the sun, to disperse themselves across the Earth, and to forgo cities.
This anti-technology choice actually made sense to me on several levels. For one, the survivors kind of had no option. As we were reminded in the final episodes, the fleet was running out of basic supplies, including fuel, ammo, and toothpaste. They were triaging patients in sick bay. The Galactica was dead and the other ships were falling apart. The idea of building another Caprica was kind of far-fetched.
The decision was also strategically sound. I took it that the Cylon colony was fatally damaged and probably got sucked into the black hole. But Cavil and the others are still out there in one form or another. If they happened across the new Earth and found cities and an orbiting fleet, they might decide to attack. As the show ended, though, the Cylons would go right past the planet without batting an eye.
Finally, one can sympathize with the position of the survivors. They might have said, "We have all these wonderful inventions; how much good have they done us? Our inventions brought us from billions of people across 12 planets to 40,000 starving souls on a primitive rock." Going Walden and breeding with the natives probably sounded pretty good at that point.
I didn't take it that they were going completely Amish. They did talk about distributing provisions, presumably some things like antibiotics, blankets, etc. But still, I get their position.
So I liked the ending. They could have cut it off about 30 seconds earlier, though, before the dire warnings about Japanese robots. Styx drove that point home years ago.
