Seriously - among people I know, the SGs are jokes. They are NOT taken seriously and are considered the worst kind of popcorn nonsense SF.
These days, yes, unfortunately. There was a time when SG-1 was pretty good, though....I wonder how much of the credit for that goes to Jonathan Glassner.
After backtracking and noting when he left and how SG-1 changed around that time, I'd say he was responsible for a lot of what gave Stargate its unique identity at the start. After he left, the replacements tried to keep up the same thing, but it ended up seeming hollow, because they were just imitating someone else's vision, that apparently they didn't understand.
That's what they need to change about Stargate. The people in charge now need to come up with their own vision, assuming they have a vision at all.
