Just an intro: When Firefly was on TV, it was at an awkward time for us so we only got to see a couple of episodes. When we heard the show'd been canceled, we were sad and resolved to watch it on DVD. Well, 3 DVDs later and we're totally hooked (my husband put it best when he said "I think I have a crush on a TV show!" - he even made me put the theme on his ipod) and psyched for the movie.
My favorite characters are Jayne and River, maybe because they have the most potential for growth? Inara comes in a close 3rd, and then Zoe because I can't resist a woman who kicks that much ass.
I'm very glad to have found this community! From looking through the archives, I've gotten answers to a lot of questions I had.
