Agreed with the last 2 posts, I'm just watching out of a sense of duty now (my wife is the one keeping us in it). I can Only endure so many close-ups of June having quiet mental breakdowns; I actually burst out laughing at her eyebrow twitch in the last episode. And yeah, Josh Lynam just appears to be there for deus ex machina opportunities.
I also think a show that unfurls its plot lines so excruciatingly slowly owes us some further explanation of what happened to leave the world infertile. Yes, the colony scenes gave us a hint, but it's about time they put some meat on those bones.
