This was an average/above average episode - I enjoyed it. Very Sheppard-centric, and we get to see quite a bit of his background. It was nice to see Ronon accompany Sheppard, but where was Teyla? The story was interesting enough, but these Earth civilians have enough material and knowledge to build whole human replicators with consciousness? Here are some other thoughts:
Well, we finally get to see Carter again...for 15 seconds or so. At least we got to see Dr. Bill Lee - now that's what I call a red head! And we get to see Bates again - too bad Telya wasn't there...
Blades of Glory - I could just see Ronon on ice skates and twirling around!
The fight scenes were pretty good against that T-1000 model :)
I knew Ava was hiding something, although I didn't know she was a replicator until they made it obvious.
The solution at the end was fitting - Star Trek also had a few episodes where the consciousness was stored in some computer simulation at the end as well.
Overall, a decent episode.
