Dr. Horrible, that is.

This week, Joss Whedon's "Dr. Horrible's Sing-Along Blog" is being released. It stars Neil Patrick Harris, Nathan Fillion and Felicity Day in a wonderfully compact musical look at the world of superheroes and their villains.

In typical Whedon fashion, it takes a warped look at the whole topic, giving us a sympathetic bad guy and a jerkwad good guy.

Now as much as I like Nathan Fillion, this one belongs to Neil Patrick Harris from start to finish. Every single line delivery is perfect, and if there's some kind of acting award out there for weird little shows that are only released on the Internet (watch at Dr. Horrible's Sing-Along Blog or buy it through iTunes for just $4 for all three episodes), Neil's going to win it, for sure.

NOTE: MySpace now has the full three-act series up in its video section.

I downloaded the first two Acts yesterday and I've watched them three times each already...they get better with each viewing because you're getting to know the songs.

Oh, yeah...they're not kidding about it being a sing-along. If you liked the musical episode of Buffy, this will be right up your alley: in the first two Acts--less than half an hour--there are about five songs including some very nicely done duets.

This thing's a blast: Acts I and II can be streamed from the site I posted above, with Act III going online tomorrow. Go and enjoy.

EDIT: Act III is up, and it's just as much fun, though a bit darker than the first two bits. As with all things Whedon, the end will leave you thinking about it well after you finish.
