@thetopher , All great point , I happen to think those points and unattractive traits were on purpose , the thing about her succumbing to utilitarianism by the end something she always fought the Watchers Council against is particularly damaging , and that is the full cycle purpose of S7 , until there is a finale course correction when Buffy pulls through with ingenuity, unorthodoxy and feminist humanitarianism. This wasn't supernatural slayer power to echo Buffy's last line of the series "It was Buffy."
@DeepBlueJoy , "Buffy Rocked! Great generals care, but send people out to die anyway. It's necessary." This a male dominated maschoism glamorizing of war and violence, you can not have effective war campaign without propaganda , about the greater meaning, the successful outcome, and personal heroic glory. In truth this is another damaging rationale Buffy succumb to , the potentials were no better then her as a sixteen year old , except worse without slayer powers, remember "I'm sixteen year old, I don't want to die" now Buffy is willing to send innocent girls out to die just like she was , she's always known it was not right, until challenged by the prospect of there being no other way to save the world and the billions of people in it without taking the position of the Watchers Council that the greater good is what matters. She realizes there is another way, another form of sacrificing that doesn't involve "sacrificing" a innocent like the realization on the night of The Gift and she rallies the troops similarly to the night of Graduation, where they all get to make a choice to be in this fight.
And It is brilliant, to put it like this, Revolution, the forcible overthrow of one social order in favor of a new system or government will never work because human nature remains the same, its meet the new boss, same as the old boss, sort of like what happened with Buffy but Rebellion, is a personal act of insubordination, subversion and open resistance to an established government or ruler. That is a revolt that will last.
