I was going to start this post off singing the praises of TV god Joss Whedon — you know, the divine creator of all that is good and holy in the Buffyverse (Vamp Willow decked out in black leather for one). But then I realized that calling him a genius on AfterEllen.com is like preaching to the choir. I might as well say women are hot. (Duh.) So, I’m going to skip the Joss love-fest and just point out the fact that the man can do it all: He turned a failed feature film into a TV show (Buffy the Vampire Slayer), a canceled TV show into a feature film (Firefly/Serenity), and me into a comic-book lover (Fray). It should be no surprise then that he’s about to break new ground once again with what has to be the first-ever “Internet miniseries event” called Dr. Horrible’s Sing-Along Blog.

The official site for the “supervillain musical” starring out actor Neil Patrick Harris as a mad scientist (is there any other kind?) went live this past weekend, and the trailer has already sent fangirls and boys everywhere into an online tizzy. Check out what all the buzz is about here.

That looks awe – wait for it – some, as Neil’s character, Barney (from How I Met Your Mother), would say. The teaser, of course, doesn’t give away too much. I guess we’ll have to tune in to find out if it’s as good as Buffy’s Once More with Feeling or just a way to pass the time until Dollhouse debuts in the winter. But one thing is for sure: NPH is the perfect choice for this kind of campy villain. He can sing, he can do comedy (see the HIMYM reference above), and he’s already played a doctor (paging Doogie Howser!) on TV.

The cast also includes Firefly’s Nathan Fillion as heroic Captain Hammer and Felicia Day as potential love interest Penny. Extra fan points goes to anyone who recognized the actress as Vi, one of the slayers-in-training from the last season of Buffy. Anyone? Just me? Yeah, I’m a geek.

The first installment of the three-part series premieres July 15, with Act Two and Act Three of the show following on July 17 and 19, respectively. You can watch all the webisodes for free through July 20, and then Team Whedon is hoping to make them available for download — or better yet — on DVD with tons of cool extras. My inner stalker fangirl is *squee-ing* with delight.

It’s safe to say that I’m already hooked. How about you? Are you going to sing-along to Dr. Horrible’s Sing-Along Blog?
