From io9 comes “A Spoiler Free Review Of The New SGU“, here’s some bits and pieces but be sure to go and read the whole thing!

They’re back!
Next Friday, Stargate Universe is back! And if you can’t wait a whole week, check out our spoiler-free review of the next episode. Can the series keep hitting the higher standards it set in the last episode?
What the hell happened to Young? gah!
Here is the official synopsis. Beyond that, I promise I won’t spoil anything besides what we already know… but if you don’t want to know anything at all, stop reading.
Young accidentally finds himself on board an alien vessel before quickly transporting back onto Destiny. When the expedition tries to get into contact with the aliens, they find themselves under attack.
Aliens!
But back to the part of the plot that we can reveal — the aliens. Thank god for aliens. I’m not going to reveal what kind of aliens, they are but I will say they’re in the trailer. Beyond that, I want you to be surprised, because they are awesome. We know SGU wrote and filmed all these episodes months ago, but it’s almost as if they listened to our mid-season complaints, and then delivered. It’s a big wide black world in space, and it’s about damn time some other creatures popped their heads in.
I will also say that this is the first time in the history of SGU that I’ve been thankful for the communication stones. I’m still pretty firmly on Team “Airlock The Stones,” but this episode utilized them in a different way that made me thankful they existed. I highly doubt this I will ever feel this way again, because I’m not sure what happened in this episode could be repeated again and maintain the interest, but the stones really stepped up this episode
And Rush,
Now the big question: is Rush back? What do you think? SGU would never get rid of such a valuable actor and character, but is he back on Destiny? You’ll have to wait and see.
