The YouTube clip provides a good overall idea of Stargate Universe aka Stargate SGU Season 1. Stargate Universe SGU the Second and Final Season features 20 episodes on 5 DVD. There are loads of special features including commentary track for each episode. Unfortunately Stargate SGU got cancelled and season 2 ends with a cliffhanger that will probably never find closure.
The final season begins where the previous one left off. The Lucian Alliance is nominally in control of the Destiny ship and the Terrans are prisoners. Stuff happens and some of the Lucians are prisoner on the ship. Rush gains full control of the ship but fails to tell anybody. There is tension between some of the Lucians and the original Destiny crew while the usual tensions between Rush, Camille, and Young are still going strong.
A few of these issues get resolved, a few new ones crop up. Things get more interesting with episode 7 and Rodney Mackay visits later on in the season.
The writers for this last season of SGU rode the Deus Ex Machina to work every day so lots of stuff happens because of or through the magic of the Ancients.
Originally enough the show ends with Destiny under attack.
There are many theories as to why SGU - Stargate Universe had only two seasons due to diminishing viewership. My guess is there is an inherent dislike for shows where in the civilians vs. military conflict the civilians are the less honorable faction. Add to this two of the most important civilians are Camille, a nagging bitch on wheels, and Doctor Rush, a self-centered wackjob. Then again, there are only so many times you can pull the old “the Ancients did it’ out of the tophat.
Also those familiar with the Stargate franchise, especially Atlantis, had a sense of déjà vu all over again, even in terms of supporting characters –was there really a difference between SGU’s Eli and Atlantis’ Rodney? There is such a thing as Stargate fatigue.
