SG-1 was great but would get goofy sometimes. That's OK by me. It's nice when a show doesn't take itself too seriously and given that they had so many seasons, they could afford to do so. I own all the DVDs of this one.
SG-A I watched it but only first-run. It was a poor retread of SG-1 with the same mix of characters. Just different people playing them. I will not bother buying the DVDs
SG-U - I love it when they take a known universe and set it on it's head. It's one of the reasons I loved BSG so much. Yes the story was slow to develop. I'm patient. It's sad that it's been canceled. It had a lot of potencial.
But from a Syfi angle, I agree with a lot of folks around here. There's very little interesting sci-fi left. It's one of only two reasons I subscribed to the DISH network. Comedy central was the other reason and that was only for South Park.
I can get South park the day after it airs at their website.
I can get any SyFi stuff I want the following day at HULU.
I no longer subscribe to DISH.
