One of the things that surprised me most about Dr. Horrible was the quality of the music. I knew Joss Whedon had written a musical episode of Buffy The Vampire Slayer that got great fan reaction, but I’ve never seen it, so I didn’t know how good he and his brother were with music.
These two songs, the finale of act 1 and the start of act 2, are easily my favorites (though I love the first song of act 1 quite a bit as well).
I really think musically, “On the Rise” is probably the best song in the video. The interplay of the characters’ voices and lyrics is fantastic, plus it rapidly sets the tone for act two, which shows exactly what the song says – Dr. Horrible’s evil on the rise. This single video almost makes me believe a musical TV show could succeed (but then I remember “Cop Rock” – and I wonder if the general TV audience would be any more receptive now than in 1990).
Combine that quality music with the humor, and the quality story, and you have an explanation for the attention this internet-only little project has garnered (okay, it doesn’t hurt that Nathan Fillion, Neil Patrick Harris, and Joss Whedon all have rabid fan-bases).
The thing that might get me to actually buy the DVD when this comes out? Supposedly the commentary is going to be done purely in song. That is just too original of a concept to miss.
