15 Best Sci-Fi TV Shows Of The 21st Century

Centring around a phenomenal series of performances from its virtuoso star Tatiana Maslany, Orphan Black was a dark sci-fi mystery series which interrogated the morality (or lack thereof) behind human cloning.

A co-production between Canada, Britain, and America, Orphan Black fused a dark satirical discussion of what makes a human with bruising action and a twisty mile-a-minute plot, but it would all have been for naught without Maslany’s staggering performances. The actor took on five main roles for the show, and it’s her mesmerizing skill in switching between guises which will keep viewers hooked to this dark and daring cult offering throughout its five season run.
