Galactica Finale?
I'd say 'What the frak', but that phrase was old back in the '70's...
SciFi had this big thing that this was going to be Galactica's final season, and I was rather looking forward to the show being over. The snails pace at which the plot moved was agonizing, but that's probably mainly because I cared so little for the human drama that unfolded each week, and even more for most of the characters in the show. Sure, I wanted humanity to survive, but frankly most of the humans on the show were pretty pathetic, you secretly ended up rooting for the Cylons.
Anyway, big press about 2008 being the final season, nothing exciting about the commercials for coming episodes, nothing at all about a countdown to the final epidodes, then suddenly, they've found earth, they have an alliance with the Cylons, and everyone's pissed because the planet they found is a wasteland. Laughed my ass off.
As finale's go, this one was, I'm sure, a huge letdown for fans. Maybe they'll go do a DVD or something now, who knows. At least now they've got a prime spot for some new show, or maybe just run old Farscape episodes. But that would be too much to hope for...
