Firefly is not doing well in the ratings but Fox has ordered 3 more scripts to be written after the first 13. So it might continue to be made and the later scripts are going to have more adventure in them:

"Looks like," says Whedon. "We're hoping that we'll get some slow growth, which is what Sandy Grushow said before this season ever started. He said, 'Look, you're going to be hit with baseball. It's not an out-of-the-box thing, we don't expect it to be.' So there's something good on that side. They're letting us keep going, and it really feels like we're ready to hit our stride."

"The shows that we're working on now have the adventure and the excitement that FOX is looking for, along with all the character stuff, which is why I show up."

"I think we've found it," says Minear. "I do, I do."
