none of them, you can't really do much with a Goa'uld except keep it in a fish bowl.
Loved the SG series, Atlantis was my semi-favorite until the constant representation of pale skined ancients that varied from forced attempt at being enigmatic to being no different than humans in terms of persona, not to mention being predominantly white(yes there are a few darker tones shown), no racism intended (lawl how could that be "checks skin colour")
kinda svcked that there wasn't that much of a development to the ORI and Wraith compared to the Goa'uld, the origin/lore episodes for both were pretty....swift
Whats Stargate infinity? (supreme Embarrassment)
I knew SGU was gonna bomb (in my eyes) the moment they announced the hook for the series and how the formula was altered, I was really intrigued about the whole artificial structure at the "end" of the universe premise they lightly touched upon but that didn't seem to go anywhere.
liked em over all may they go down in history as a decent series back in the day, like Firefly....Firefly was sixy.
