Way to get rid of every character from the movie (except Jack and Daniel) in the very first episode

I mean, I understand why they had to Goauld up Sha'uri (though not why they had to change her name to Sha're), so Daniel will have a reason to join the SGC. And I guess Skaara would want to help search for sister-dear/hang out with O'Neill, and I can see reasons for not having a kid on the show, but what about Ferreti and Kowalski? They can't be SG-2 for a while?

Ah well, I liked it-- nice to finally have all the clip-show flashbacks and other references pieced together.

I do have to wonder, though, if people who hadn't seen the movie would find certain bits confusing.

And look! There's Walter! Hi Walter!
