Naomi: "Is there a plan B?"
Holden: "Yeah, make sure Plan A works."
- The Expanse, S2 E13, "Caliban's War"
Still no date for The Expanse to appear on Amazon Prime without an extra charge. This fall, is what I've read. You maybe have heard that SyFy cancelled The Expanse in May 2018, after three seasons. But Amazon picked it up a few weeks later and is funding Season 4.
The Expanse gets the top award, in my opinion, for making life in space as compatible with real physics and engineering as any sci-fi show I've ever seen.
