The ending was great !
It's wonderful that Jack had the balls to do what he did.
It shows that Adult sci-fi isn't about swearing or sex.
Agreed. It really annoys me that there is not more sci fi like it being produced. After the recent star trek film and the new Dr who which turned out to be terrible, I had given up hope on a lot of the new sci fi with some hope for the next series of SGA.
The ending turned out to be excellent. I also liked the reason they wanted the children and the fact it took over 4 hours into the story to find out what it was.
