I don't get what people think they want out of Firefly. It absolutely would have fallen apart in another half season. They were already doing call-back episodes and shrinking the world in the one season they got.

I've only ever seen two opinions on Firefly: it had 3-4 good episodes and a lot of filler. Or it was 100% bangers. I'm in the second camp (Shindig being one of my favorites). It's basically an exceptional mini-series that the showrunner wasn't given a chance to ruin. I'm very happy with that.
