I've not yet watched all available episodes of Black Mirror, but my impression so far is that this is completely unlike any other series (anthology or otherwise) I've seen. The stories are diverse and seem to come out of left field, which is brilliant in its own right. They do share a common theme, however - examining the darker side of technology and how it's come to dominate our lives for better or worse.

Can't really say much more without spoiling it but one doesn't need to be a science fiction/fantasy fan to truly appreciate this show. It's got a powerful message and will, in my opinion, inspire viewers to contemplate some of the larger questions facing the human race. The drama and acting are uncommonly good to excellent; the pacing taut and intense. It's an enjoyable experience as much as it can be an uncomfortable one, but the discomfort is a good thing; after all, how many t.v. shows truly make us use our brains these days?
