@TV series point+ The Expanse is back. Battlestar Galactica it is not but there have not been many better sci-fis since then. In fact, I'm struggling to think of one.
Legion is pretty wild and weird, especially Season 2 which just started.

..but I agree with you. We have not had a BSG replacement yet.
Well I am three episodes into The Expanse. So far I am enjoying it but, like everyone else said, this is no BSG. BSG had me addicted by the third episode.

I did find the novel series this show is based on. I downloaded a sample of the first book and enjoyed the sample but can't bring myself to spend $10 for the whole book... yet... another 10 to 15 minutes and I may have to cave...
