An interesting aspect to investigate (the idea of a Goa'uld positively influencing Earth history and seeming to take an actual interest, if a harsh one, in the development and survival of their people), but not coherently developed and definitely not in a manner which benefited the narrative. The abduction story and Yu's reasoning (even if he is going senile) was vague at best and illogical most of the time. The characters were not developed particularly well nor skillfully - not in a significant way that would warrant the story. Overall, unnecessary and underwhelming. And long for the actual content.
