As is true with most things, I was a bit late coming to the party on this one. Dr. Horrible's Sing-Along Blog is what happens when a bunch of talented people with some time to kill create a super-villain/musical hybrid outside the constraints of a studio. It's funny, it's entertaining, and it's further proof that Neil Patrick Harris might be the greatest actor of our generation. (Yes, I'm including Johnny Depp, Heath Ledger, and David Spade in that count.) For those of you in the United States, the Hulu version of the film is embedded after the jump.
