"The Expanse" is rather good

The Expanse is a great big lump of space opera that must have cost a fortune to produce. (I tried to work in an "The Expense" gag here, but I couldn't make it work. Oh well.)

The spaceships are some of the best I've ever seen on TV and the narrative is rattling along at a furious pace. Set all around the solar system, a few hundred years into the future,  it has earthers, martians and belters (folks from the asteroid belt) at the brink  of interplanetary war.

There's political chicanery, space battles and some rather unsavoury extra-terrestrial stuff oozing around the place. Some bits of the plot seem to get a massive build-up and then disappear, but there's more than enough going on to keep you occupied now that Star Trek Discovery has finished its run.
