Yes, Buffy did horrible things in Season 6, but I could buy how screwed up she was. Season 7 Buffy seems very cold to me, even though she's supposedly 'better'.
Thanks, you've just helped clarify how I feel in my mind. This is going to sound wanky, but I still thought I knew Buffy in season 6- I could see a clear line from who'd she'd been before to who she was then. I didn't always like her, but I got her.
And then season 7 Buffy came along and I just didn't recognise her- especially early season 7, where she was some photocopy of season 2 and 3 Buffy.
