Okay, now this is my jam. I would LOVE to sit down and read this entire thread one day, but that's slightly more ambitious than I have time for right now.
Anyway... wow, so some of my favorites....
-Season three is my favorite season. Looking at it from beginning to end, it is just one of the best. The whole season-long theme being the "road not taken" is such a powerful one. We are consistently shown Buffy having to deal with, for the first time, the choice associated with being a Slayer through her watching Faith. We start out the season, and she's living another life, away from her Slayer life, and how she truly can not escape it because it's who she is. As teh season progresses, Buffy meets Faith, a Slayer who (like Kendra) is another representation of what being a Slayer could look like.
-My favorite episode is often a tie, between The Wish (for the reasons mentioned above) and season five's Fool For Love. Spike is such an interesting character, although until FFL, you don't know how interesting. It's beyond a simple origin story. You learn how he acquires every "cool," "Spike"-like thing attributed to him. At the end of the episode, we see him in a darkened alley with Buffy, where she utters the words that left him feeling humiliated and rejected a century+ prior. "You're beneath me." And you realize, not how bad a** Spike is, but how despite his name, his accent, his scar, and his jacket... he's still that nervous, nerdy fellow hiding beneath a facade.
-Last, but not least, (I realize this is getting really, really long) my favorite character is Faith Lehane. Based on a lot of the movies and tv series (Wrong Turn, Tru Calling, The New Guy) people have questioned whether or not Eliza Dushku can act. I don't care about any of it. I thought she was perfect as the dark, redemptive Slayer. She brought such power, sexuality and vulnerability to a potentially throw away character. (I heard a rumor that they were planning on killing her off at the end of Bad Girls, Buffy was to have gone to Faith's apartment and found her hanging, having killed herself.) An aspect that was always interesting was that despite herself, she really always wanted to be Buffy. To have her stability, support, family, friends. My favorite Faith moment will always be in Angel during her first appearance, when she broke down while battling Angel in the rain, and she finally gave herself up.
yeah, that's a lot. Just wanted to give you a buffy-intro because I think I'll probably be here a lot.
