A tense and interesting drama, Orphan Black explores differences in human psychology as well as ethical boundaries in science. It's fun to watch the mystery unravel, but it is even more entertaining to watch Tatiana Maslany play over five different clones throughout the series. I'm sure that there are more clones and mysteries to come as the show becomes more complex and more interesting.
A sci-fi show following a young lady who witnesses the suicide of a girl who looks identical to her. Tatiana does a brilliant job of not only portraying many different characters, but also having those characters accurately impersonate many of her characters. With such a thrilling and action packed plot line, Orphan Black is definitely one of the most addictive shows I have come across.
