The theme for Stargate Universe has been revealed by one of the shows executive producers.
Joseph Mallozzi has confirmed that Stargate Universe will be more of an arc based series when compared to Stargate SG1 or Stargate Atlantis whose episodes were more standalone except for the occasional two or three parters.
Universe will have more season long plot diversity and character threads running through every single episode. The show will also feature some stand alone episodes but they will still contribute to the ongoing story aboard the Destiny.
