Dr. Horrible... Just That, Perhaps?

My sister is adorable. She told me today that I should watch Dr. Horrible's Sing-Along Blog. Even Cole chipped in, saying it was the best thing he's seen in ages. I was curious, so I knew I had to give it a try.
Going into this, I knew it was a bad idea... I've had terrible experiences with musicals (they literally make the hairs on my head stand up), and my opinion of funtime is quite different from that of my sister (we're similar, but really, we aren't).
The trailer, if you will...


I realize I'm just not cut out for American humor.
I need something distinctly British to linger on the palette...
