As everyone who knows me should know, I lurve Buffy the Vampire Slayer. I think that Buffy is the most bestest and socially pertinent show (that used to be) on television.
Well, quite by almost accident, I stumbled upon Dr. Horrible, by Joss Whedon, A.K.A. Mutant Enemy Productions, A.K.A. The Guys Who Made Buffy and Firefly (also an okay show).
Dr. Horrible is a super hero musical featuring the convoluted escapades of an evil supervillain. Except he's not really evil. Kinda. There are plot twists, and the ending is really, REALLY juxtaposin' to all conventional, corporate, feel-good standards of storytelling.
There's also obvious symbolism discussing social change through violent means.
You can watch the whole thing on the intarwebs until midnight, when they take it offline, like bitches, and start making you pay some of the monies to download it and watch it.
So hurry up and watch it, if you like that sort of thing.
