I never got the impression there was much momentum for any more sequels anyway, Serenity felt like the bone they were willing to throw. This was a time before show revivals (rather than remakes/reboots e.g. BSG) were common, it was very surprising when they did it for Family Guy.

Firefly has a rabid fan base, but it's not very large. The movie did... okay. Enough to pay for itself, but not enough to interest anyone in making more content in that universe.

When the show was first released it was cancelled after half a season because it was expensive to make and couldn't compete in the ratings with slap-dash, almost free to produce "reality TV".
