I'm completely addicted to this show. We don't have TV here, but we do have Netflix and I just discovered it. I love it (despite that it only ran for 2 seasons). That Joss Whedon is a clever guy (he did Buffy and Angel too).
It's a sci-fi/fantasy show, so if you're into that you should check it out.
Did they even finished season 2? I saw the first few episodes of the season and stopped watching out of bitterness towards Fox for canceling it.
Joss is my man and I hate seeing his work get canceled. When Firefly was axed a part of me had died.
I'm glad Buffy survived seven full seasons (my favorite show). Didn't care for Angel, though.
