I don't think Telford's point was that the Goa'uld should've been left in charge, but rather that the SGC had no business going out into the galaxy, destroying the dominant power structure, then packing up and going back home, leaving everyone else to rot. "Hey, guys! We've liberated you, now have fun!" Someone inevitably steps in to fill the vacuum, and so you've got the Lucian Alliance.
They may be brutal thugs but at least it's humans ruling humans, which seems like a step up from humans being ruled by false gods with belly worms.
I didn't mind the use of SG-1 characters at all. O'Neill was funny. It was cool to see Daniel again despite him not getting a lot to do here.
One thing that wasn't explained at all was why the Alliance wants to get aboard Destiny. For one thing, they have no way back once they're aboard. And for another, it's a rustbucket. Maybe they think Rush is blowing smoke, but I just don't see the profit motive in it for them. Seems like a hell of a lot of work for a questionable reward.
The Telford/Young scenes were good, and it's nice to see Young backing off from jumping to conclusions given what happened with Rush. He seems a bit more thoughtful now, though still willing to take extreme measures when the situation warrants. He's gotta be bluffing about the air, though. He may not mind seeing Telford dead but he and Rush are seemingly on better terms now and I can't imagine he'd really sacrifice Rush.
The baby shower with TJ was actually a good idea. The crew is finally starting to feel like a family, which is a natural place to go on a show with this sort of premise.
I really felt like the show was firing on all cylinders this time around, so I'm going to give it a 10. If they can keep this up for the rest of the season I may be willing to go back and forgive some of the glacial pacing of the first half of the season, given that they were laying the groundwork for all this.
