Just saw this episode the other day, and it's definitely one of the best eps of S6. I love how Joss is so willing to take risks, to so question the very concept of the show. It was very much like "Gingerbread," only ten times more extreme. For a while I was afraid that it would be made clear that it was all the demon's doing, but I'm glad they chose to make us wonder. I gasped when I saw Joyce crying and Buffy still in the hospital. That last scene should go down in history as one of the best endings of an episode. I am however glad that they didn't follow up on it, that would have had me really worried. It works better as a one time thing.
