*Raises hand* I'm a huge Firefly fan. It's easily one of the best television series ever made in my opinion, it's a crying shame it got cancelled. If you're interested or a fan of comics, they brought out two series of 3 issue comics called "Those Left Behind" and "Better Days" that bridges the gap between the end of the series and the start of the movie.
I am a fan of Firefly. I have it all on a DVD boxset. Unfortunately I didn't get into it or even hear of it until it was canceled. A coworker at the time lent me the movie. I later bought the boxset. I wish it had lasted longer. Come to think of it I also didn't get into Buff or Angel until after they ended as well.
