Ehh, there were plenty of nifty little details in that show, but they don't end up meaning much since the plot gets hijacked by a supernatural deus ex machina.
(And with The Expanse having shown such signs from Episode 1, it almost seems like nobody can make a good sci-fi TV show that has spacecraft but not the supernatural.)
The Expanse is a book series first, and the TV show follows it pretty well. The book series, still way ahead in the future, doesn't really pull this device. Turns out the first season/book of the series are just the precursor to an advance-alien-civ sort of plot.
The Expanse isn't hard sci-fi, but it's a pretty decent sci-fi thriller in my opinion.
