Battlestar Galactica (Seasons 1–4)

Battlestar Galactica (2004–2009) is the landmark sci-fi drama you can watch online on iFILM — four seasons, 73 episodes on Syfy. Humanity is nearly gone.

The Cylons, machines built by human hands, launched a coordinated nuclear strike that wiped out twelve colonies in a matter of hours. Fewer than fifty thousand people survived. The aging warship Galactica, commanded by the uncompromising Admiral William Adama (Edward James Olmos), becomes the only military shield for a ragged civilian fleet drifting through space. President Laura Roslin (Mary McDonnell) runs what's left of the government from a cramped cabin aboard a passenger liner, while pilots Starbuck (Katee Sackhoff) and Apollo (Jamie Bamber) fly outnumbered every single mission. Then there's scientist Gaius Baltar (James Callis) and his dangerous secret — one that could tear the fleet apart from the inside.

Showrunner Ronald D. Moore turned the space-opera format into a hard-edged study of survival, paranoia and moral compromise; the series earned a Peabody Award and redefined what science fiction on television could be. Stream every season of Battlestar Galactica online on iFILM.
