Hmm... Movie of third season screened in 2015, so third season probably aired... 2012? So 2010 for the first season airing? An 8-year delay, then, in this timeline... hey, that could explain how it actually got a decent run. Due to the general chaos after 2I, it took time for relative luxuries like television filming to resume, and not all the same companies survived. Joss pitched Firefly to somebody other than Fox, whose executives had more sense and patience (or less competition for time slots due to the 2I disruption), allowing it to build up the critical viewer base to succeed commercially while it was airing.
