Orphan Black - New Series coming to BBC3

Imagine seeing yourself one day. Not just someone who looks like you, but You. Except it's not. 

That's exactly what happens to Sarah, our streetwise Orphan hero in Orphan Black. Sarah finds another “her” and slowly a mystery unfolds.

Who is Beth? Why are they the same? Are there any more?

Part thriller, part comedy, part sci-fi (in the sense that it's fiction based on Science – not flying spaceships or things). Orphan Black is coming to BBC 3 in the UK.

Despite having a great cast it's not an ensemble production. The show belongs to the main star – Tatiana Maslany. You've probably never heard of her before, but by the end of the first episod alone I guarantee you won't forget her! Each character is unique and distinctive from the others, and what really shows is when one character is impersonating another. They look the same (of course), but you can tell from the mannerisms that it's x being y.

The mystery unfolds for us viewers at the same pace as it does for Sarah, learning piece by piece what's going on. Sometimes it can be frustrating; wanting to know slightly more than we're told, but the nuggets of information are placed before us to find.

Characters are mentioned and introduced quickly, the return later on like old friends stopping by on their way past. The supporting cast are great with not a bad actor or actress among them.

The only one niggle I have with the whole premise is how someone can impersonate someone else so well that even work colleagues can't tell the difference. That aside, the show has got me totally hooked, and I'm glad it's already gained a second season!
