Watch Dr. Horrible's Sing-Along Blog

Dr. Horrible's Sing-Along Blog is an incredibly witty and dark musical comedy that was written, produced, and released by Joss Whedon in 2008. The show tells the story of Dr. Horrible, played by Neil Patrick Harris, a mad scientist who dreams of one day ruling the world, earning the affection of his lady love Penny, played by Felicia Day, and defeating his annoying nemesis Captain Hammer, portrayed by Nathan Fillion.

The story takes place over three 15-minute webisodes, each containing original songs and musical numbers. Dr. Horrible constantly documents his activities in his video blog, and reveals his sinister plans to the audience as he attempts to balance his evil schemes with his budding romance with Penny. However, things take a dramatic turn when he becomes more desperate to realize his plan for global domination and finally defeat Captain Hammer to win the heart of Penny.

The show's commentary on society is at times cynical, dark, and witty. It has a lot to say about self-preservation and ambition, as well as the idea of the underdog who fights against the system, and how power and privilege play a role in both. Dr. Horrible's desire for power and influence is both relatable and deeply flawed, and the audience is left wondering throughout the show if he will actually become the ruthless ruler he so desperately wants to be.

One of the best aspects of the show is the fantastic cast of characters, all of whom are played brilliantly by their respective actors. Neil Patrick Harris is perfectly cast as Dr. Horrible, managing to balance his comedic timing with a subtle hint of pathos. Nathan Fillion, meanwhile, is hilarious as Captain Hammer, the self-absorbed and arrogant superhero who spends more time flexing his muscles than actually fighting crime. Felicia Day is delightful as Penny, the good-hearted and optimistic romantic interest of both Dr. Horrible and Captain Hammer. Her performance brings a charming lightness to the show and provides a stark contrast to the darker themes.

In addition to the main cast, the show also features some fantastic supporting characters. Simon Helberg, from The Big Bang Theory, makes a standout appearance as Moist, Dr. Horrible's henchman, who has the power to make things slightly wet. They even use this strange power to make some dry jokes in the show. There are also some other villainous characters, including Bad Horse, who is the leader of the evil organization the Evil League of Evil. The cast and characters in Dr. Horrible's Sing-Along Blog work together so well, bringing some impressive chemistry, that it almost feels like they're all part of a professional musical comedy troupe.

The show's songs are a standout feature, all of which were written by Joss Whedon himself, and are well-constructed with catchy melodies and clever lyrics that poke fun at musical tropes while managing to stand on their own. Even though they're often humorous, they do not at any point sacrifice quality or beauty. Some standout numbers are "My Freeze Ray," "A Man's Gotta Do," and "Everyone's a Hero." The musical numbers in the show range from upbeat and lively to slow and mournful, but they are all really fun to sing along to.

Like many of Joss Whedon's works, Dr. Horrible's Sing-Along Blog has become something of a cult classic, and it's not hard to see why. It's an incredibly unique and fun experience, with fantastic music and iconic characters, all of which are portrayed by extremely talented actors. It's wonderfully satirical and cynical towards contemporary society, and it has a lot of relatable themes for audiences to explore. The show is a nod to classic musicals while bringing in contemporary subjects like blogging and technology.
