Description (quoted from Wikipedia link above):
Battlestar Galactica (BSG) is an American military science fiction television series, and part of the Battlestar Galactica franchise. The show was developed by Ronald D. Moore and executive produced by Moore and David Eick as a re-imagining of the 1978 <em>Battlestar Galactica</em> television series created by Glen A. Larson. [...] The cast includes Edward James Olmos, Mary McDonnell, Katee Sackhoff, Jamie Bamber, James Callis, Tricia Helfer, and Grace Park.
The series garnered a wide range of critical acclaim both at the time of its run and in the years since, including a Peabody Award, the Television Critics Association's Program of the Year Award, a placement inside Time's 100 Best TV Shows of All-Time,^([5]) and Emmy nominations for its writing, directing, costume design, visual effects, sound mixing, and sound editing, with Emmy wins for both visual effects and sound editing.^([6]) In 2019, The New York Times placed the show on its list of "The 20 Best TV Dramas Since The Sopranos", a 20-year period many critics call "the golden age of television."^([7])
Battlestar Galactica is set in a distant star system, where a civilization of humans lives on a group of planets known as the Twelve Colonies. In the past, the Colonies had been at war with an android race of their own creation, known as the Cylons. With the unwitting help of a human scientist named Gaius Baltar, the Cylons launch a sudden sneak attack on the Colonies, laying waste to the planets and devastating their populations. Out of a population numbering in the billions, only approximately 50,000 humans survive, most of whom were aboard civilian ships that avoided destruction. Of all the Colonial Fleet, the eponymous Battlestar Galactica appears to be the only military capital ship that survived the attack. Under the leadership of Colonial Fleet officer Commander William "Bill" Adama (Olmos) and now-President Laura Roslin (McDonnell), the Galactica and its crew take up the task of leading the small fugitive fleet of survivors into space in search of a fabled thirteenth colony known as Earth.
It may also be worth revisiting a series that was so clearly influenced by the aftermath of the 9/11 attacks to see how well it holds up over time. (Consider also, say, <em>24</em> as another example of such a 9/11-influenced series.)
Great find. Your link didn't work for me, so here's a desktop version. Someone should post this on bigger TV subs.
