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.

I love Dr. Horrible. I heard they may be doing a sequel.

Yeah, I've heard that too... one wonders what it'll end up being about, lol. There's also some prequel comics in existence (regarding Captain Hammer, Penny, and Moist, respectively.)

And the music is so catchy...

It's great! ^.^ really funny and you can't help but want to learn the songs and sing with them xD

The news about the prequel is new to me. And yes the songs are extremely catchy.
