Well, I have to admit it... I started watching Firefly because I missed the whole Buffy-mania* and I wanted to jump on a bandwagon.
But now I really, really like it and I, too, am pissed-off that it only lasted half a season.
I haven't seen Serenity yet, I figure now that I'll wait until I see the whole tv series. Although it appears that's only one more episode...
*I saw the movie in the cinemas when it came out, but apparently Wheedon fans like to pretend the movie never happened. But I guess that if it never happened, the tv series wouldn't've either?
