12 Most Anxiety-Inducing Sci-Fi TV Shows EVER
2. The Walking Dead
Another post-apocalyptic horror drama concerning a world overrun by the eponymous monstrosities, Shawshank Redemption helmer Frank Darabont's adaptation of Robert Kirkman's long-running cult comic series The Walking Dead may be one of America's most popular shows, but don't let that fool you.
This brutal and uncompromising sci fi series is as bleak a show as you'll ever see, and many of its cruellest moments come from (no surprises here) human characters who show a capacity for inhumanity and amoral viciousness which would put the zombies to shame.
Yes, it may go somewhat off the rails in later Darabont-free seasons, but this one is still well able to leave viewers plenty shook ten seasons deep.
