8. 'Orphan Black' (BBC America)
Like Pretty Little Liars in so many ways (even if there isn't much demographic overlap), this science-fiction sleeper is a hallucinatory fable about identity meltdown — all the dangers and risks of becoming a girl, becoming a woman, becoming human in a society that's like one big clone club. The second season saw the clone sisters (Sarah, Cosima, Alison, Helena) on the run from the evil Dyad Institute, with all these different clones played marvelously by Tatiana Maslany. Orphan Black never pauses to catch its breath, and each episode throws in way too much plot for anyone to follow. But as Jordan Gavaris' scene-stealing assless-chaps-wearing Felix likes to say, you can't hide in minimalist furniture. And there's nothing minimal about this show.
