Actually Superstar, there is a Buffy thread, but it went off the page some time ago.
And I wouldn't call the end of season 4 a resolution, Cavi. If anything, it was building up to season 5, because for once Joss knew that they had one more season at least. But the other seasons ended with a sense of finality.
Oh, and I just got Firefly. Can't wait to try it out.
