I logged into Hulu today and saw that Dr. Horrible's Sing Along Blog was avalible. I hadn't watched it before though I knew I would enjoy it because Joss makes things I enjoy when he's being hassled by Fox executives, and it doesn't hurt that I like all the actors.

The one person I didn't know was in the show was Moist. I've been watching Big Bang Theory for a couple years and so it was fun to see Simon Helberg in a different role, even if it wasn't all that different.

I largely already knew the story, but when you have people as good as the actors in this knowing the plot only takes you halfway, and of course Joss is able to surprise me even when I think I know what to expect.

I don't know how long this has been available on Hulu, but it's one of the best things I've seen in quite some time and well worth watching.
