Buffy: The Musical was amazing. Joss Whedon wrote all the songs himself, and it covered so many Broadway styles from ragtime through swing, 50s, 60s, 70s, and 80s (though not much 90s), with what I perceived to be stylistic nods to Les Miz and Into The Woods, and Rent, as well as several others.

An excellently well told story and, unlike so many other 'aberration-style' episodes from other shows ('a very special Blossom', etc.) this one was actually a highly pivotal arc episode, setting the path for huge changes for nearly every person in the show.

After last season's 'Body' episode going without so much as an Emmy nomination, I don't have any expectations, but I do have high hopes for this one come next September. It seems that once a season Joss creates an absolutely amazing work ("Becoming - Part II", "Hush", "Body" and now "Once More, with Feeling").

It just keeps getting better.
