Anyone seen it? Thoughts? Also, what have you heard about the potential sequel?
For those not familiar, Dr. Horrible's Sing-A-Long Blog is a web-movie-musical-...thingy created by Joss Whedon. It's only 45 minutes long, and you can watch excerpts of some of these for free on Hulu
; it centers on the misadventures of the titular supervillain. I highly recommend it if you have a little time.
