I didn't hate Zhaan's episodes, but they never involved me much, because they always felt kind of superficial to me. "Oh, here's this character who's practically perfect in every way, so, uh, sprinkle some angst on top?"

Zhann's character was an odd case to me because in season 1 it felt like they had some interesting plans to turn her darker/uncontrollable, but then it never really went any further than that. The same with Stark in season 3 I suppose. People always say that plans changed for Zhann later on because of the make-up, but I'm not sure that was an issue in season 1? Yet after she lets darkness and evil back in in That Old Black Magic and it's made out to be such a turning-point for her as her race just can't do that and not let it overcome them, it's only followed up on with her being a bit irritable and snappish in DNA Bad Scientist, Jeremiah Crichton, and Durka Returns. (And really I never got why D'Argo describes her as cold for wanting to give up the search for John in JA, they had apparently been looking for him for a few months, so it only made sense to give up on the search after that long when they had no clue where he was. It wasn't like they were all as close in that period that they later became, that it should have been seen as such a shocking attitude)
