"Hush" is indeed excellent. That and "The Body" from Season 5 were the two I think that could have won an Emmy, "Hush" may have even been nominated. I would probably rank the seasons like this: 3, 2, 1, 6, 5, 7, 4. Season 7 I liked more when I went back and watched it on DVD than on TV, but I wasn't a big fan of the ending or the Slayerettes. Also, Anya might have been my favorite Buffy character (Dawn probably my least favorite). I think Season 6 is underrated. I didn't really like Tara until I saw the musical episode. Drusilla reminds me of this Patti Smith cover:
