The science fiction space opera is by now a well-known genre, and yet somehow The Expanse is hard to describe. Let me try to sum it up at its most basic: The Expanse is a show about space. It is a show about society, about resources, about people with passions and problems and desires and—most especially—about what happens when all those things collide.
It is also, in a word, excellent. The Expanse's fifth season is the best since its first, a long-awaited high-stakes payoff to several seasons' worth of setup. If you drifted away from the show during earlier seasons, like something accidentally dropped in microgravity, this new season makes it worth finding a way to come back.
The setup
For the first few seasons, The Expanse was concerned entirely with our own solar system. In its vision of the 24th century, we have fairly widespread access to spacefaring technology, just all at sublight speeds. The moons of Jupiter and Saturn might be accessible, but not so much the stars beyond.
