In case you’ve been living under a log lately you might have heard of “Dr. Horrible’s Sing Along Blog“. This is a very amusing mini movie that was released online by Joss Whedon creator of Firefly, Angel, and Buffer the Vampire slayer.

While it doesn’t have vampires or spaceships it does have super heroes and super villians and makes for a very amusing musical. The various musical numbers are catchy and the whole thing is professionally done. Both Neil Patrick Harris, and Nathan Fillion can sing a lot better than one might initially expect. While it’s not as much fun as “Once More With Feeling” it is probably one of the more entertaining things I’ve watched online.
