Watch the whole of the season, then come back and try again. Don't judge something you haven't watched the whole way through.
And, in case you hadn't noticed, Buffy doesn't have telepathic powers, Willow does. Hence how Willow can hear Buffy's thoughts, and call Xander into the kitchen with them.. Buffy doesn't call him, Willow does- its THE WITCH that has the telepathic powers. Obviously.
Andrew was an interesting twist in the story- he might be an accessory, but he's also a pawn, but an unwilling one, which makes it more interesting. Andrew as a character is also extremely funny to watch.. he tries to integrate himself into Slayer Central, but it doesn't really work. He's not a threat, so he's allowed to be.
Willow and Kennedy I disliked, but that's because I didn't think enough time had feasibly passed for Willow to be entering a new relationship- its a personal thing. And have you ever been addicted to anything?? It's exactly right that you wouldn't be able to do it/use it/whatever if you were recovering from an addiction. I think that was portrayed perfectly- if you're an addict, you have to abstain, even if it's hard- and that's exactly what Willow was doing- what did you want, for her to miraculously get over it and be fine and carry using magic as though season 6 hadn't happened? Because no-one would have a problem with Willow coming back rehabilitated and back to normal, as it's such a normal thing to happen after a few months!
Buffy isn't talking about how great and powerful 'she' is, per se, more the 'slayer' is. Which could be any of the girls if she dies. And as she says herself, she's got a wicca who won't-a, and no-one else with any sort of power... it is all about her, especially now. What is everyone else going to do?? She's the one who has to stop it, and I'm sure she feels more than partially responsible for everything considering it's the fact that she lives that's the catalyst for all this.
And as for the turok han part, I think what she did was brilliant. There was dissension in the ranks, and the best thing she could do was to unite them all. They thought that if Buffy couldn't defeat the thing, what chance would they all have? So she showed them just what it means to be the slayer, she showed them that it was just like any other vampire and it could be beaten- it's called giving them hope, resolve and something to fight for. It was a great idea.
Comparing that to the Cruciamentum is just laughable. That was a psychotic vampire she was trapped ALONE with, while it held her mother hostage and she had NO powers. It's a completely different situation- in this case, Buffy has power, there are dozens of people, they are far enough away from the Turok Han to be out of danger and if worst came to worst, I'm sure Willow would break from her recovery to sort it out... Buffy isn't stupid, it wasn't a rash decision but a carefully calculated one that was extremely successful.
Edit:
Quote: Bored of the Dead- 'You were expecting something else. PR went in expecting to be disappointed, so he was. There is no way Season 7 would have been good enough for him. He isn't a proper fan of Buffy, he should be removed from BB and the world'
*snorts* Of course, what WAS I thinking?? It's simple fact!
But I just don't understand how someone can be so unbelievably critical of something they haven't seen all the way through!!! Watch it, then come back and criticise it, and we might, just might, take something you say with more than a gain of salt (maybe a pinch even, if you're lucky).
