The best Black Mirror episodes offer up a horror anthology series based more on the fears of technology than on monsters, ghouls, and post-apocalyptic landscapes. While it owes a lot to shows that came before, like The Twilight Zone and Outer Limits, this series is about computers, sci-fi advances, and speculative dystopian storylines. At the same time, it also followed The Twilight Zone’s emphasis on taking these fears and using them to shine a light on current social issues.
