Finally all the pieces in place. I purchased Series 1 & 2 a while back as I had seen initially a few episodes on Sky. I became immediately hooked, being a Sci-Fi buff. The whole series is carried by one actress, Tatiana Maslany. She plays so many characters not just over the complete series but in each individual episode. It is no surprise she has won awards. But not only her, there is a very high standard of acting from the supporting actors/actresses as well. It is a well put together series, not just from the Sci-Fi aspects but also as a mystery, Drama, thriller and a little comedy. A definite recommend to watch.
