From Wikipedia:
Dr. Horrible’s Sing-Along Blog is a 43-minute tragicomic musical produced exclusively for Internet distribution. It tells the story of Dr. Horrible (Billy), an aspiring supervillain, Captain Hammer, his nemesis, and Penny, their mutual love interest.
I just finished watching Dr. Horrible’s Sing-Along Blog on Hulu.com. Let me be the 1,000,000,000th person to say how much Joss Whedon and Neil Patrick Harris rule.
I had heard many good things about it, and was just looking for a chance to watch. Since my wife fell asleep early and I didn’t want to watch Doctor Who without her, I decided to give Dr. Horrible a go. I’m so glad I did. Just a cool idea, and story.
If you haven’t seen it, you need to check it out. Here’s a direct link to it on Hulu.
