(S01E12) What is regarded by many to not be one of the better seasons of this show, 'Prophecy Girl' is always highly regarded as a stand out episode, and rightly so. So much is set up for the remainder of the series, just from this episode. It's clear from watching even from the first episode that this episode was filmed before the show debuted, as there are scenes from this episode in the show's opening credits and, I believe, some of Buffy's nightmares in previous episodes.
