Oh, wow, that was brilliant. Just when I think DW can't surprise me, it does; and it does it in spite of having no Awesome Donna, and basically pulling a twist on that staple of horror, the possession story. I was on the edge of my seat the entire time; David Tennant was at the very top of his game; and the only (yes, only) tweak I had was that the Hostess' change of heart seemed a little too arbitrary. I bought it, but I would have bought it more if it hadn't happened until she heard the creature using the Doctor's French phrases.
Anyway. BRILLIANT, I say.
Cannot WAIT for next week. *bounces*
