They're rebooting the movies. They were sorta working on a trilogy back in the day that never came to be, so the original creators (I think) are revamping it with a trilogy. It's the only thing I ever read fan fiction of (SG:U 3rd season) - and it was GOOD.
I wish they had touched more upon the 4th race. It was more of a macguffin unfortunately.
SG:origins should be good - I hope?
Watch Amanda Tapping's Sanctuary series. 90% greenscreen. 1st season was crowd funded, on SyFy after that so the quality picked up. Good story lines. hard to explain - saying steam punk in current times with current tech with creatures doesn't properly explain it.
