Yes Stilly, that's the one. I haven't seen all of the episodes, and I only stumbled on it by accident when I was recording a show next to it on the TV schedule. I haven't liked every episode I've seen but I have liked a lot of them. In my youth I was always partial to reading Sci-Fi short stories so it fits with that.

My other fave Sci-Fi TV show is Fringe. Each episode is a separate story but there is continuity in the main characters and their ongoing situation throughout the show. I stumbled on that one by accident, watched the re-runs, bought the DVD's and watched it again. Like Black Mirror, it can be dark, sometimes scary, but always food for thought about life, the universe and everything.

Which reminds me, of course, of The Hitchhiker's Guide to the Universe by Douglas Adams, and also the Terry Pratchett books, movies and TV series.
