Well i thought the endin was rushed, like the lead up to it was huge and in the end where was the First ???? sure it cannot take a physical form but at least u should of seen the First fade away or sumfin.
And the deaths of some seemed like they were forced, eg potential slayers and Anjanka. And i dont get the whole Spike being a marter(spellin?)
if it were upto me make it another episode, hav the First invade buffy's soul as she dont really hav one, dawn is forced to kill buffy to save the world, Robin kills Faith while tryin to kill Spike for revenge and Willow is overwhelmed wit power and kills a few then dies. but that is jus evil !
