I’ll start: my personally favorite sci fi that that I wish more people knew about is Orphan Black. It features Tatiana Maslany really showing off her acting prowess. Basically, she plays a street rat who encounters an identical but well off version of herself who jumps in front of a train. In discovering this apparent twin’s life, she realizes there’s yet more of her and that they’re being killed off.

The cast, both Tatiana and not-Tatiana, are really good at embodying their characters and the world is neat at showing something that could actually be happening under our noses this second.

Edit: here’s a low spoiler example

Its probably a common answer, but “Measure of a Man” from Star Trek: The Next Generation. It makes me hope for a future like that, where people can settle their problems by talking it out and debating, and even change their minds. Whenever I think about what Star Trek is really about, I think about Measure of a Man. Its such a shame Paramount’s Picard show disrespected it so badly.

The Expanse was consistently amazing. Some of the episodes were so good they left me speechless.
