I wonder if this will be what Star Trek: Voyager should have been:
After unlocking the mystery of the Stargate’s ninth chevron, a team of explorers travels to an unmanned starship called the Destiny, launched by The Ancients at the height of their civilization as a grand experiment set in motion, but never completed.
What starts as a simple reconnaissance turns into a never ending mission, as the Stargate Universe crew discovers the ship is unable to return to Earth, and they must now fend for themselves aboard the Destiny.
The crew will travel to the far reaches of the universe, connecting with each of the previously launched Stargates, thus fulfilling the Destiny’s original mission.
I never got into either SG-1 or Atlantis, but this seems well-poised to recapture some of that epic feel from the original movie.
