Oh you have no idea how much I LOVE this show.
I missed it on the Sci-Fi channel here when it was originally shown and seen maybe 2 of the episodes.
They did a whole repeat from the beginning just before the movie came out and I instantly fell in love.
I absolutely love Joss Whedon and his ability to write for ensemble casts. I loved Angel and Buffy and I love his run on Astonishing X-Men.
Firefly was so quirky and just so so funny. I bought the series for myself for Yule and I wached the whole thing in one night. Plus all the extras on each disc.
I love all the characters, but as you can tell from my Av/Sig combo. I'm in love with the man they call Jayne.
It also has some of the greatest lines in tv ever.
"Every planet has its own weird customs. About a year before we met, I spent six weeks on a moon where the principal form of recreation was juggling geese. My hand of god. Baby geese. Goslings. They were juggled."
"My god -- you're like a trained ape. Without the training."
Jayne: "My dear boy. I hope you are well and that you get this soon in your travels. Thank you for the credits you forwarded, they have helped as Matty is still sick with the Damplung. He waves hello, and so does your father. He is in good spirits and there was layoffs but the foreman said no one can weld like a Cobb so he has employment still. I made you the enclosed Ooh! Enclosed! The enclosed to keep you warm on your travels. Hope to hear from you soon, love, mother." How's it sit? Pretty cunning, don'tchya think?
Wash: A man walks down the street in that hat, people know he's not afraid of anything.
Jayne: Damn straight.
So many quotes I can use. But I'll stop there before this post looks like an essay.
And the actors didn't look model-perfect after being in a fight, imagine that! 
... NNNNNNNNNNOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!! *cries* I thought I'd gotten rid of you guys... I'm just kidding, really, I have a crazy friend who has a never-ending obsession with Wash, and she's gotten me obsessed with Mal/Nathan Fillion. Buy you see, here's the thing, for me... I just don't get it... My friend has to explain in intrecate detail just what is going on because it's too much thinking for me to do while I'm trying to follow the already complex plot. That being said, I do find War Stories/the Mal+Wash torture episode, to be very well done because it was pretty easy to follow, good acting, good dialogue, great characterization (which is something I'm obsessed with), and lots of fun action. Hopefully you crazy Browncoats are happy with me now, but unless Frodolyn comes along, I highly doubt I'll be back here again, so bye!
