What Jeopardy Champ Thinks of Joss Whedon's Firefly

Ken Jennings is best remembered as the longest running Jeopardy champ who won $2.52 million in a record 74 games. He also happens to be a darn funny writer (I'd say "d*mn" but I don't want to offend his Mormon sensibilities). Here's a post from his blog on how he was recently introduced to the cult hit Firefly, what he thinks of it, and why he confuses it with Keri Russell's show Felicity.

Incidentally, the leads of Felicity and Firefly have starred together in a movie that came out last year. I know it's not time to play One Degree yet, but does anyone know what movie I'm referring to?
