This show is an amazing, fast paced action drama. Tatiana Maslany effortlessly plays at least seven clones, each with their different personalities and mannerisms. She plays each character so well that you sometimes forget that it's actually just her playing all of these clones. John and Graeme and also magnificent writers, they have done a fantastic service to all of their female characters and the plot gets better with every episode/season. I seriously cannot fully express my love for this show in words.

Extremely well done, the lead actress is amazing. In my head, each of her characters are acted by different people. Every episode has something surprising, but in hindsight makes total sense. The only thing that disappoints, is having to wait until Spring for the next season...

Ignore the haters, 1st season is the weakest (focus on selfish deadbeat mom-brat Sarah) but hang in, only gets better from there when Helena is finally included with sestras. Deserves and needs a much better recap than measly 2 minute 'previously on' to summarise intricacies of conspiracies involved. 4 seasons on amazon prime
