Dr. Horrible's Sing-Along Blog

Highly recommended. It's what Joss Whedon was up to during last year's writer's strike, and features Neil Patrick Harris and a hilarious Nathan Fillion (on loan from Desperate Housewives) as his do-gooding arch-nemesis. The pacing is a touch slow at times, but it's funny and most definitely worth watching. It's "Once More, With Feeling," minus the demons and add the superheroes.

The series will only be available online for a few weeks, then you'll have to buy it on iTunes or on DVD. It looks like it'll run about 45 minutes (kind of like an episode of a TV series), but I'm down for the time.
