The Expanse season 3 episode-by-episode reviews: a sci-fi going from strength to strength

Here are all of our reviews of space-set sci-fi The Expanse's impressive third season, available now in the UK on Amazon Prime Video...

Based on the series of novels of the same name by James S. A. Corey, The Expanse is set in a future where humanity has colonised the Solar System. It’s a space-based political conspiracy thriller, in which crime meets intergalactic tensions that threaten an already very fragile peace between nations.

Children Of Men and Iron Man writing team Mark Fergus and Hawk Ostby brought Corey’s novels to the small screen with great ambition and depth… which is probably why it got cancelled.


May 2018 was a tumultuous time for fans of The Expanse. Two thirds of the way through season three, Syfy announced it wouldn’t be renewing the show. It was a frustrating move, particularly as the third run of the space-set political thriller had been receiving an overwhelmingly enthusiastic reception from all quarters – critics, fans, amalgamated review sites, that woman at work, those guys chatting on the bus… everyone loved it.

Enter: Amazon Prime Video, on a white steed. It delighted fans by picking up The Expanse for a fourth season, which is due to arrive on the streaming service later this year. In the process, it also nabbed the UK streaming rights to the first three seasons from Netflix. All episodes of The Expanse arrived on Amazon on Friday the 8th of February 2019.
