Right, yes. I know SG-1 and they would not let that happen to the program. We've seen them fight exactly that kind of change in Chain Reaction and, really, most of the episodes with Kinsey.

Even with AUs, the stories I prefer are the ones that still feel the same, even if they're set in some completely different place and time. If it doesn't feel right, the story usually doesn't draw me in and I'm left sitting there thinking, "Huh. That didn't work."

Just so, yes.
