So I just watched "Once More, With Feeling." Yes, yes, I'm 13 years late, so sue me. What's important is that it was really, really good. (Spoilers obviously.)
I'd heard of "Once More, With Feeling" long before I actually started watching Buffy (about two to three years ago now), but I honestly didn't think it could live up to the hype. I mean, I expected it to be good, but I was sort of expecting it to be a lightweight version of Dr. Horrible's Sing-Along-Blog. But it was actually better.
The music was great, the dance numbers fun, and the writing some of the best the show's had for awhile (though I haven't hated Season 6 as much as some forewarnings led me to believe I might). The script was witty, self-aware, and even pushed forward some major plot developments, like the Scoobies learning Buffy wasn't in hell, Tara discovering Willow's amnesia spell (bad Willow!), or Buffy and Spike getting a relationship upgrade. And I loved the villain (who I guess is called "Sweet?"). Totally over-the-top in all the best ways.
And now I want to buy the album.
