I only watched the very first episode of Black Mirror. It’s one of the most depressing things I’ve ever seen, and a big part of that is its sheer banality. I can’t speak for other episodes—multiple people have assured me that there are much better ones—but the first one really does boil down to “phones bad”. Except they used bestiality to make this incredibly groundbreaking point.This isn't as delightfully on-the-nose as the OP's example, but there's this strain of criticism that gets leveled against Black Mirror, including a recent CollegeHumor video, that treats it as a Luddite series and critiques that aspect, when one of the running themes of classic sci-fi short stories (Bradbury's "The Veldt" and Asimov's "Liar" come to mind, e.g.) is that technology shines a light on who humanity really is inside. It empowers and amplifies people. And, literature being literature, what's reflected in that mirror is usually pretty negative because literature loves showing humanity at its worst.
But many critics completely miss the "yeah, humanity kinda sucks" point and jump straight to the "technology bad" interpretation.
