The first half of the season is the weird, awkward part. It's the only "section" of the series that I regularly skip when rewatching. The last half was pretty much on par with the rest of the show, though.
Yeah. There are a few in there that I still watch (Crichton Kicks, John Quixote, etc). It's not really until you get to the halfway point with "Unrealized Realities" that it gets back to traditional Farscape form.
Even so, the first half of the season has a lot of subtle stuff going on that you might not realize the first time around.
