I'm predisposed to like anything from Josh Whedon, but his newest, an online webisode show, Dr. Horrible's Sing-a-Long Blog, is the cat's jammies.

The 3-part show is hosted through Hulu, and can also be downloaded through iTunes. The first two shows are available, and the third goes up tomorrow. If you're a fan of Firefly, keep an eye out for "Captain Hammer", and you'll see an old friend. However, everyone in the show is exceptional, including Neil Patrick Harris as Dr. Horrible, Felicia Day as Penny, Dr. Horrible's secret love, and, yes, that is Nathan Fillion as an outstanding Captain Hammer.

What an absolute treat. And to add to the enjoyment, also check out the fan site. But check the show out quickly, because according to the fan site, the freebie shows will end July 20th.
