I think 'The Expanse' is outstanding. IMO, it's easily the best sci-fi TV show of all time (certainly of the "hard science" variety), behind the magnificent BSG (reboot version). They try very hard to get the physics right. The only real "macguffin" is the Epstein Drive, a very efficient fusion drive that allows constant acceleration/deceleration for months at a time, thereby providing artificial gravity and cuts the travel time from one solar body to the next to weeks or months rather than years. Not hard to imagine something like that will eventually be invented. Our current understanding of physics allows it.
The asteroids that house human habitations are mined from the inside, then "spun up" to provide centrifugal gravity for the inhabitants. There is no faster-than-light travel, transporters, lasers/phasers or other tropes of standard space opera. Mars has hundreds of millions of inhabitants by this time (200 years in the future) and become a military superpower (they invented the Epstein Drive and gave it to earth in return for independence). They are practically single-minded in their goal of terraforming their planet.
In addition, there is a lower caste of people who live in the asteroid belt, mining it for its mineral wealth and selling it back to Earth & Mars. So there are 3 major population groups in the solar system and the plot lines mainly involve how those entities interact with each other. Then, something strange is discovered on one of the moons of Saturn and the status quo suddenly changes...
The story & plot lines are extremely well done and based on the excellent series of novels by dual authors who write under the pen name of "James S.A. Corey". I've been keeping up with the book series and they just released the 8th of 9. So the story is almost complete. The TV show roughly follows the books, with one per season. Syfy Network cancelled it last year (too expensive to produce) and Amazon Video picked it up. S-4 premieres this fall. Free for Prime members. If you like "hard" sci-fi, you should climb on board the Rocinante
and enjoy one helluva ride.
