Battlestar Galactica: The Story So Far
Just saw on Major Nelson that Battlestar Galactica: The Story So Far is available for download from Marketplace. Gamespot has a good article summing up the show as well. To quote:
When it debuted in 2003, the new Battlestar Galactica was greeted with skepticism. After all, it was a remake of a 1970-'80s series with a strong cult following produced by the Sci-Fi Channel, a cable network then infamous for its low-budget TV movies of the week.
Surprisingly, Battlestar Galactica proved the naysayers wrong. Its innovative plotlines, which were created by ex-Star Trek: The Next Generation writer Ronald D. Moore, won it critical acclaim and solid ratings. The series has also garnered a major following for its unusually gritty atmosphere. Instead of the clean-cut, sober officers of the Star Trek shows, Galactica's crew is an unkempt, hard-drinking lot whose demoralized dialogue is peppered with the fictional expletive "frak."
In 2004, the show was picked up as a full-time series. It ended its most recent season, its second, in March with one of the more shocking cliff-hangers in sci-fi television history. Such boldness helped the show win one of this year's Peabody Awards, the prestigious honor for excellence in broadcasting, which it shared with CNN, NBC Nightly News, and South Park, among others.
The third season of Battlestar Galactica is premiering in October, and the Sci-Fi channel is pulling out all the stops to promote it. It has put together a television special, titled Battlestar Galactica: The Story So Far, summing up the key events of the Battlestar Galactica miniseries and its first two seasons. The special will air on all the cable stations owned by Sci-Fi parent NBC Universal, which includes Bravo and USA, as well as the West Coast affiliates of the NBC broadcast TV network.
I can't stress enough how good this show is, and what you're missing out on if you're not watching. I'll be the first to say that TV programming is mostly drek. I have friends who give me the hardest time for having the home theater I never use to watch TV (would much rather use it with movies and games). Battlestar Galactica is one of the first TV shows in a long time that I personally think is worth watching, and I'd encourage you to check out the free summary show if you're curious. That said, if you know you're going to watch it, I'd skip the summation and just get seasons 1 and 2 on DVD. I'm waiting for the recently announced HD-DVD versions - the show is filmed in high-def, and looks spectacular. No, I don't know why only the SD version is available on Marketplace - bummed by that. 
P.S. - Muffy the robot dog is nowhere to be seen. This is a good thing.
