I’m not I’d quite call it hard SF, but give the current show <i>The Expanse</i> a shot. It at least tries to build a somewhat plausible space society. Also has pretty good writing, characters, acting, and camera work.<p>From a plausibility perspective (plausibility of both the society and the characters) it’s far and away better than Star Trek, Babylon 5, Battlestar Galactica, etc.
