Watched "Once More, with Feeling" again today at lunch. It was even better on a second viewing.
The first time I saw it, about half-way through I thought that it seemed familiar to me. I finally realized, at the end, why it did. It reminded me of The Bitter Suite, from Xena. There were a lot of heavy, emotional issues on the table, and a musical helped clear the air.
But with Buffy, while everything is out on the table, there's no reassurance that everything is all right now. Next week should be interesting.
