Aww yeah! My kind of thread. Check out The Expanse on prime. Man in the High Castle.
Inside No 9 (I believe they are in season 6, but streaming only has 3 seasons currently)
Black Mirror
Orphan Black
Doctor Who of course. (I can go on for days)
Dollhouse
Torchwood (DW spin off)

I heard Cowboy Bebop is excellent (anime)
Red Drawrf (older brit comedy)

Can’t recommend Altered Carbon enough. So freakin good!

One of my go-to Sci Fi films is The 5th Element. I believe Alamo has movie parties for this once in a while.
