I'm not talking about her complexion, I'm talking about the shape of her features, especially in profile. She looked a lot like Gina Torres, for instance. There's more to ethnic variation than skin tone, and she was drawn to look more sub-Saharan African than Middle Eastern/Semitic.
Near as I could tell, she did not look remotely like Gina Torres, what an odd thing to say. The shape of her facial features was not noticeably un-Semitic... unless I missed something, but I don't think so. I suppose I'll have to have a look when/if there are images available online.
As for the religion question, I don't know about the other episodes but this particular one seemed reasonably even-handed to me. Yes, they talk about superstition and the anger of the gods -- but they also portray En'hedu'anna's hymn to Inanna reverentially and frame the entire episode as an extension of the themes of the myth of Gilgamesh. I didn't see it as taking a particular stance for or against religion. Maybe other episodes have been different.
