If you're old enough, you might have seen the original 1978 Battlestar Galactica and Galactica 1980 way back when. The re-imagined series debuted with a miniseries on December 8th, 2003, and concluded 73 episodes later on March 20th, 2009.
The new Battlestar Galactica, created and produced by Ronald D. Moore, was the talk of the town on science fiction websites and entertainment magazines alike. It was a reboot of the two previous series, but maintained its own story line with a darker tone and rich characterizations, intrigue and action.
