Critic Reviews for The Expanse Season 3

All Critics (26) | Top Critics (4)

The Expanse isn't perfect television, but entering Season 3 it is undeniably confident about the story it's telling, and more importantly the kind of stories it wants to tell.

Apr 12, 2018 | Rating: B+ | Full Review…

Such a highly-addictive series thanks to the phenomenal production values, terrific characters, meticulous world-building + intriguing plots with genuinely-high stakes. It's everything one wants in a sci-fi series, or any TV genre for that matter.

A great season with stimulating and fascinating science fiction. [Full Review in Spanish]

Feb 27, 2019 | Rating: 3.5/5 | Full Review…

The Expanse is one of those shows that easily lives up to its name. Not only does the title evoke the vast and dangerous emptiness of space, but this is a show crammed full of detail and interaction.

Mar 1, 2019 | Rating: 8/10 | Full Review…

Expanse Season 3 is fantastic, high-budget sci-fi that delivers all I want out of the genre with style. Can't recommend you check it out enough!

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

In a lesser show, some of these developments might come off as cheesy or convoluted, but here they feel like a shot of juice straight to the veins as we eagerly followed the protomolecule and Holden's seemingly fated collision course.

Dec 21, 2018 | Full Review…

That's an overwhelming amount of mostly good science fiction. But hear me out: The Expanse is better than all of these shows. Need proof? Thomas Jane is in it and he has the most hideous haircut I've ever seen.

Dec 21, 2018 | Full Review…

It hit its narrative stride this year, as all the pieces from the first two seasons' many narrative threads at last came together to form a cohesive whole.

Dec 21, 2018 | Full Review…

Chatham and Mitchell are both talented actors, so pairing them together in an almost mother/son dynamic was a great move by the writers. Hopefully, Season 4 will develop their relationship even further.

Dec 21, 2018 | Full Review…

The end of The Expanse's third season has arrived and in a drawn fashion perfectly befitting the rather solid season that it has led up to.

Dec 21, 2018 | Full Review…

This finale would have left the series on a satisfying note, wrapping up some of the bigger storylines, and leaving on an optimistic note that humanity could put aside their differences and work together,

Dec 21, 2018 | Full Review…

The way the show lets its narrative bleed from one season to another means that there's never any downtime, and no need to ramp back up again,... right now, is on the verge of all-out interplanetary war.

Audience Reviews for The Expanse: Season 3

    Great story, thrilling, extraordinary. Looking forward to see more.
  • Sep 20, 2020
    While The Expanse suffers from Baking Bad Syndrome (creating artificial tension from pointless twists), both the cast and the writers seem to be more comfortable in their shoes than during season 1.
  • Sep 18, 2020
    It keeps getting better and better
  • Sep 14, 2020
    Best modern Sci-Fi series
  • Sep 10, 2020
    I just read a viewer rating that said "wooden characters, unlikable actors, derivative plot and world-building." It's people like this that take ratings down on good entertainment. I'll bet he didn't like Babylon 5 either. This is some of the best sci-fi I have seen in a long time. I am on the edge of my seat every episode. I cheered when Jeff Bezos announced that Amazon was picking up Season 4. And now there is a Season 5 coming! There is a reason this show still has high ratings, despite certain unappreciative individuals.

    Looks like Gunny Draper took her first acting lesson so not quite as terrible as the first two seasons, but still a major detractor in every scene she's in. The rest is just excellent though, so covers for Draper well.

    Great show ,really enjoyed it.
  • Jul 02, 2020
    Another great season, with touching moments.
  • Jun 21, 2020
    Best Sci-Fi show ever. Your next binge is here!!! There is something in EVERY episode that keeps you on the edge of the couch.... this is probably my favorite show of all time.
  • Jun 05, 2020
    The whole season moved really well and I was able to get right back into it after a 2 year hiatus.
