Tv Season Info

The second season of the sci-fi drama series opens with the introduction of several Martian military characters, including Bobbie Draper (Frankie Adams), one of the loudest voices promoting war against Earth. Meanwhile, Avasarala (Shohreh Aghdashloo) survives an assassination attempt and ramps up the war between Earth and Mars. On the Rocinante, Holden (Steven Strait) and Miller (Thomas Jane) recover from the radiation poisoning they got on Eros and decide to store the dangerous Protomolecule in an abandoned asteroid mine for future study. Together with Fred Johnson (Chad L. Coleman), Holden and Miller go on a mission to avenge the Eros genocide, only to make a disturbing discovery: An interplanetary conspiracy is trying to control the Protomolecule and use it as a weapon against alien life forces—and the genocide on Eros was the result of a deployment test! Their mission becomes that of finding a way to stop the conspirators once and for all, by any means necessary.

Critic Reviews for The Expanse Season 2

All Critics (21) | Top Critics (5)

The show's epic scope... remains intact, as well as its always impressive production values and effects. But there's more focus to the first four episodes of the season than expected, thanks to more of the characters uniting in proximity to similar goals.

Feb 2, 2017 | Rating: A- | Full Review…

A great 13-episode ride, or more accurately, a great end to a 15-episode ride, and then a great 8-episode ride that teases the next season well...

Feb 19, 2019 | Rating: 5/5 | Full Review…

The show maintained a high level of tension while letting characters develop quietly and intimately over two hours. The science fiction elements, as well as the special effects, were strong.

Jan 10, 2018 | Full Review…

The Expanse is the best sci-fi TV show since Battlestar Galactica.

Jan 5, 2018 | Full Review…

If well-researched science fiction is your bag, season two of The Expanse is sure to thrill, confound, and delight in equal measure. Just make sure you're paying attention.

Feb 3, 2017 | Rating: 4/5 | Full Review…

Yet as suspenseful as this was, and as much as I think the second season has represented a leap forward in quality for the series, it's a bit wonky from a structural perspective.

Top Critic

Now that we know who's behind most of the mysterious events, and trying to instigate war, The Expanse has a chance to be even better now in its second season.

Feb 3, 2017 | Rating: 8.5/10 | Full Review…

Unburdened with introductory world building and backed by surefooted writing, The Expanse returns as thrilling and intriguing as ever in a second season that packs just enough of a timely political wallop.

Feb 2, 2017 | Rating: 9/10 | Full Review…

Whether viewers come for the political intrigue, the space battles, or the character drama, there's pretty much something for everyone.

Feb 2, 2017 | Rating: 4.5/5 | Full Review…

It all adds up to one of the best sci-fi shows on TV at the moment.

Audience Reviews for The Expanse: Season 2

    Wow! Season 1 was great already although a little plodding at times but season two nailed it! That's some crème de la crème SciFi here!
  • Aug 01, 2019
    Best Science Fiction ever.
  • Jul 27, 2019
    Exceptionally great series. Sadly has annoying, awful audio volume level mixing.
  • Jul 08, 2019
    Another great season.
  • May 05, 2019
    Continuation of best series on TV. A classic in the making. It's consistent excellent writing and excellent cast, the Expanse only gets stronger and better, if that's even possible. Love it.
  • Apr 10, 2019
    Production quality was as good as the first season, but where the first season strove for realism in it's imagining if the future, the second season starts off immediately with the tired old trappings of liberal virtue signaling. From a silly scene in the very first episode involving a female "gunny" busting a robotic arm wrestling machine while the soy Bois jb the platoon watched jealously to the "white males ruin everything" and preachy anti-war and environmentalist themes throughout. What started out as charging toward the best show on television in season one slows to a near halt in season two. Just sad.

    Great Show, Great Actors
  • Mar 11, 2019
    As good as the first...WOW!
  • Mar 04, 2019
    This is absolutely the best SiFi series on TV, bar none. So much better than the abortion that is Star Trek Discovery.
  • Feb 28, 2019
    I almost gave up on sci-fi as a genre since not much good things happened in recent years... finally, with this show, I am so happy to give the sci-fi genre another chance. The show is excellent as well as the graphics.
