@hypolite @clacke Another great show, grandparent to The Expanse, is Babylon 5. Instead of future humans and aliens living in perfect harmony, they're a bunch of squabbling species trying to work things out. Sci-fi is a backdrop, never the focus - I cant recall a single technobabble solution the whole series. The story is about people - sure they be green skinned and red-eyed, but we can mostly understand their motivations. Has some of the best character arcs of any TV show.
