Joss Whedon’s Dr. Horrible’s Sing Along Blog is worth the hype. It stars Neil Partrick Harris, Felicia Day (from the “The Guild“), and Nathan Fillion (Mal from Firefly).

Acts I and II are available now.

Felicia Day is a great discovery. I’ve watched a few episodes of the guild, but seeing her in this, as well as hearing her sing, is a real treat.

If you think you don’t like musicals, go ahead and give this a try for two reasons. First, it’s Joss Wheedon. What more reason do you need? Second, it’s funny as hell.
