With its shared DNA from Ronald D. Moore, Star Trek: Deep Space Nine can be seen as the predecessor of Battlestar Galactica‘s 2004 reboot. Both sci-fi series are acclaimed, with DS9 holding a 91% Fresh rating on Rotten Tomatoes and BSG even higher with a 95% Fresh rating. Premiering in 1993, Deep Space Nine is a spinoff of Star Trek: The Next Generation that ran 7 seasons in syndication. Battlestar Galactica launched a decade later, first as a 2003 Sci-Fi Channel miniseries that spawned a 2004 ongoing series running for 4 seasons, as well as a prequel, Caprica, and spinoffs Battlestar Galactica: Razor, Battlestar Galactica: The Plan, and Battlestar Galactica: Blood & Chrome.
