Earth
From Wiki Frakr
Earth is the planet that everyone in all of the various Battlestar Galactica shows is trying to get to.
Boy, are they going to be disappointed; this place is a real shit-hole. Once a biosphere teeming with all sorts of life, it's lately become over-run by Humans and their various technologies and structures. The majority of other life failed to survive direct contact with the humans, sad to say. But they were delicious. *BURP*
Earth could be a paradise, if people could only get over themselves and their various delusions, and maybe quit killing each other over them, but instead it's war-torn, becoming despoiled, and rapidly turning into an authoritarian theme park.
Things aren't really that bad though; we have cool things like computers, beer, b00bz, music, the internet, sliced bread, and cheese, and Quiznos — to name a few. However, the cool is overshadowed by the crappy stuff, like Africa, Iran, /b/, anime, MySpace, World of Warcraft and that guy who directed Alone in the Dark.
So far, no über-powerful aliens have arrived to kick our asses, and no BIG ROCK has wiped out our species, so we must be doing pretty well, right?
Wrong
In the "re-imagined" series, the Fleet reaches earth mid-Season 4. They appear to land burnt-out, radioactive ruins, or perhaps Brooklyn[1], where all the major characters stand around with shocked, sad, despairing, disbelieving looks on their faces. Because on sci-fi shows all alien planets are more or less the same all over[1], it can be safely assumed that the rest of Earth is a radioactive, burnt-out cinder full of death and decay where only cockroaches and and twisted mutant talking cats can survive.
All things considered, a better Earth arrival than the original series ... *shudders*
