It really is a great series.
But a point of clarification.
Farscape did not pioneer science fiction story-arcing. It was certainly on the edge of the frontier. But it wasn't the first that had an intentional overarching story-line. It was Babylon 5.
The pilot for B5 aired in 1993. The series ran from 1994-1999.
Now, season one was a bit episodic at times. But at least 1/3 of the episodes (including the pilot) set-up events that played out, and came to bear in later seasons. From season 2 on the story arc unfurled in full force... and by season 3 almost every single episode ran into the next one (while still giving the viewer some satisfaction that at least a part of the story was completed).
Now... don't get me wrong. Farscape is a great show. But I think it was able to accomplish much of what it did because the television fields had been plowed by B5.
