if the series had been all arc and interstellar politics it simply would not be Farscape. That's Babylon 5.
I think Babylon 5 did have standalone episodes. It was one of the first space opera with a long term thru line but it had standalone character eps too in the early seasons.
Also, while I like B5 and it had some good stuff ( I enjoyed Jurasik and Katsulas) but I think Farscape got many of the drama elements "better" than B5.
