Pink and I caught an episode of FireFly way back in the day, and were recently introduced back into the 'verse by our Battlestar Galactica buddies from college.
Since, we've bought and watched the entire series on DVD and it's companion movie, Serenity. We may even have a hankering to watch them all again with the commentary on we've gotten so addicted to them.
I like them so much it makes me wish my trenchcoat was brown! :)
