After getting the Definitive Farscape collection and watching through the complete run. I think I've come to a conclusion that's not shared by most scapers. I don't like Seasons 3 and 4 as much as one or two.
For one thing, I don't think they ever really recovered from the loss of Zhaan. Jool and Norati never really filled her role.
But what really got me about season 3 was the twinning thing: Doubling up Crichton. As far as I can see this was done just so they could split the cast between Moya and Talyn and still have the 'star' Browder appear in all the episodes. Which just seemed cheap to me. The main cast of Farscape are interesting enough that they can get by without Crichton for a few episodes.
And the other annoying thing; When the Talyn!Crichton dies. His holo-message to Moya!Crichton plays rock-paper-sissors with him to prove they're still the same.
If you're going to have two different Crichtons in two different circumstances, they should be different characters by the end of it. Indeed they seemed to be going this way, without Aeryn Moya!Crichton was maybe a bit grumpier and didn't get on well with the rest of the crew. But this affect really should have been a lot more pronounced IHMO.
I'm sorry but that's just how I happen to feel. What do you think?
