This just in (and only available until Sunday night): Joss Whedon's latest effort. Those of us who worship at the feet of the master are having enormous fun with this little curiosity, so do take the opportunity to check it out. Dr. Horrible's Sing-along Blog is an online musical miniseries starring Nathan (Mal Reynolds) Fillion and Neil Patrick (Doogie Howser) Harris, along with Felicia Day as the love interest. Nicely produced by Mutant Enemy (you know, the "Grrr. Argh" guys who brought us Firefly) and just plain fun, it's well worth several minutes of your time. And it's why I'm not posting any more today, because I need to get the whole thing watched.
It'll be back (see the Master Plan), but this is apparently it for now.
