I'm working on a commentary on Joss Whedon's Dr. Horrible's Sing-Along Blog. Whedon, of Buffy the Vampire Slayer fame, wrote with a team of writers (mostly family) this 43-minute musical for the web during last year's writer's strike.
Dr. Horrible's Sing-Along Blog, in addition to opening a promising new frontier of direct-to-internet independent offerings, is another profound work about the nature of good and evil, and how so many of us teeter on either side of things as we journey through our lives.
If you want to familiarize yourself with it, you can watch it through this link:

or you can read about it (including a detailed synopsis) on Wikipedia
