"Hateful?"
Imagine if the Nazis had dug up a stargate and made contact with a well-intentioned alien civilization whom they asked for assistance as the allied armies were closing in on Berlin in 1945. And the Nazis presented themselves to these aliens as peace-loving victims of another nation's war of conquest.
Not knowing why the war was being fought, but presuming that there was likely a philsophical and ethical divide between the combatants, wouldn't the aliens want to know on which side of that divide the faction with which they made contact sat before committing themselves to render aid?
That's PRECISELY what this splendid episode is about, an allegory for that what-if scenario. If it has any flaws, it's that the reversal in Jack's trade-for-technology-no-matter-what commitment is too sudden; a more nuanced two-part episode would have been even more welcome than what we've been given.
As it is, the episode takes a moral stance, in this case against racism - as embodied by the Eurondans' barely concealed loathing of Teal'c - eugenics and genocide that the show seldom allowed itself.
Through ten years and two-hundred and thirteen episodes, "The Other Side" is arguably the series' very finest hour.
