If memory serves, I had first watched Dr. Horrible's Sing-along blog because it was a movie Heather had wanted to watch...or re-watch, I can't remember. After watching it, I have to say I was very pleasantly surprised. Dr. Horrible's Sing Along Blog is a musical about a want-to-be Super Villain called Dr. Horrible (played by Neil Patrick Harris) who's fallen in love with a girl from the local laundromat (played by Felicia Day), who herself had fallen in love with Dr. Horrible's arch-nemisis, Captain Hammer (played by Nathan Fillion). This musical does an amazing job of letting us see what the other side is like, and that the villains can be people too. Not only does it do this amazingly, but it was one of the first of it's kind, at least from what I've seen. Harris and Day leave the viewer(s) in awe with their duets, and fully compliment each other's singing styles. With music by Joss and Jed Whedon, this musical has tunes that could easily get stuck in your head if you're not careful....and Hammer is a bit of an ass. Be sure to check it out if you have not already!
