The whole spike/buffy angle threw me for six in that season. It was just so....off. And when he nearly raped her in the bathroom I sort of gave up on Spike ever being redeemed and a bit of Buffy lost me too. I get that she was hating herself and all emo because she was bought back from the dead against her will, but come on ! Grow some balls bitch LOL.
I have to say that faith is my fave slayer in the mythos. She is just so complex and in your face and would be the ultimate hag to have your back in a time of crisis ! I also thought she is one of the better fighters out of Buffy and her. Her fight against Angelus in Angel was proof of that when she wants to, faith and totally kick vampire ass with the best of them.
Out of the two originals who do you think is the better slayer, Buffy or Faith ? I had my doubts, but after seeing Faith in season 7 and then in her arc NO FUTURE FOR YOU in the comics, I think Faith is the better Slayer. She is just so brutal and to the point. PLus, she can take down Angelus and Angel as shown in the Angel tv series.
As for the season 7 angle I am still not sure where Joss is going with the whole slayer line activated plot. But, seeing how the season 8 is going so far it appears that there will be a bloodbath on our hands soon, and that many of the called Slayers are up for the count.
