Yes. It's very well done. I don't really "do" Buffy (except for Spike, who I would do in a New York minutes *snicker*), but I remember people talking about the Tara story, and I did see the last two episodes of that arc. It was a fantastic set up and delivery. It had MEANING.

I am very worried for the Captain Jack character. If Moffat really wants a clean slate, and who can blame him, Jack might become the Face of Boe earlier than he expected! Not because of Moffat... but because RTD is in a "break the toys" mood, and Jack might have no protection!
