As far as mind-bending science fiction television shows go, it doesn't really get much better—or more mind-bending—than Dark, Netflix's very first German-language show. Throughout its run, the series proved that sci-fi tends to be at its most compelling when it's trying to mess with the audience's heads. For those who loved it and are craving more, there are thankfully plenty of thought-provoking series out there that are almost as good as Dark.
