I seem to be one of the last people in the universe to have heard about this (thank you, Janis!), but in the off-chance that I’m not alone in the dark, if you’re a fan of Joss Whedon you must check this out: Dr. Horrible’s Sing-Along Blog. Starring Neil Patrick Harris, Felicia Day (who played Vi, one of the potentials, in the last season of Buffy), and Nathan Fillion, who has perfected the art of the smarmy, this is another wonderful foray into the world of superpower musicals for Whedon. The third, and I think, final episode goes up tomorrow, and I think that the episodes will only be up for a limited time, so watch it while you can!
