1.1 Natural Selection & 1.2 Instinct The show’s concept is simple, Sarah Manning, played by a very capable Tatiana Maslany, witnesses the suicide of a woman to whom she bears a startling resemblance. In what is actually a series of well thought-out and reasoned moments, Sarah steals the women’s identity and starts to live her life. What she didn’t foresee was that the woman is a suspended detective, has various relationship issues and, importantly, that the detective was investigating a strange connection with several other women that also bear an astonishing resemblance to Sarah.   As I intimated at the start, the show is not fast-paced, but there’s nothing wrong with that as long as the characterisation, plotting and acting is up to scratch so that we can enjoy the space the show gives them to develop. In this respect Orphan Black generally succeeds. It is that tone that immediately sets the show apart from the current crop of TV science fiction. This is a serious and mature approach that doesn’t shy away from some dark themes and moments, but interestingly doesn’t take the HBO approach of ‘showing all’. The fact that the show feels different and the material is taken so seriously is one of the principal reasons why I’ve bought into the concept that Instinct develops quite well, and it’s not the greatest of spoilers to reveal that this show is all about cloning. Cloning opens several debates on a multitude of topics, so there is a rich vein of material that Orphan Black can exploit. The most interesting will be the “who” and the “why”, and the first two episodes have done well to develop a sense of greater reveals to come. I believe that the show’s ultimate success will depend on how well these are tackled, so that the pay-off is equal to the effort that has gone into grounding the show into reality. At times I’m reminded of the 1988 BBC series First Born, for no other reason than the seriousness and atmosphere that Orphan Black exudes.   Admittedly, this is still early days and the show could be lulling us in one direction before going somewhere completely different in both tone and concept – but I hope it doesn’t. It’s done enough in the first two episodes to be of sufficient interest that viewers should come back for more, although how much more will depend on how well the show balances its tonal grounding with the ability to tell a coherent and interesting narrative.
