Well, to go a little more in depth with my review, I'll say that Robert Carlye's was a standout performance. I mean, I expected him to be good, but his character is very interesting- enigmatic. Granted, the writers obviously deserve some props for putting together such an interesting character, but Robert C really, really makes this guy work.
Louis F was really good too, as limited as his presence was in this first episode. I also really liked the characters of Sargent(?) Scott- sorry unsure of his rank- and Eli, as well as Chloe. These were the characters I found myself most interested in. I'm guessing they'll flesh the rest out more, but these one are the first ones I really like.
I like that this show is a bit grittier than the other SG's, but they still maintain some of the humour. And while I loved the "heroes" of SG1 and Atlantis (O'Neill, Sheppard, Mitchell types), I'm interested in seeing if they make these military types a little less perfect- that seems to be the goal, I think, and I'm keen to see them make it work.
I'm pleased that this isn't going to be SG Voyager, and that the Stargate itself will still be coming into play regularly. This was one thing I was worried about, but I think they're going to pull it off effectively.
Overall I'm pretty pleased with the first two hours, and I'm looking forward to part 3 next week. If they can maintain this level of entertainment for me, then I can see myself getting hooked on this show which will be sort of a guilty pleasure relief- I've been missing new SG episodes for a while and it'd be nice to have some new material to view!
