My rating of 10 out of 10 for a review means that it needs to be, in my opinion, one of the best things I've seen. This is normally reserved for Star Wars, Blade Runner and their ilk. This easily stands tall against some of the best TV I have ever watched, GoT and Walking Dead included. I have never enjoyed binge watching a series as much as I did this. Tatiana Maslany is mesmerising and it is phenomenal how often you forget that the 'sestras' are all her, so distinct are the separate personalities; and she finally received a well deserved Emmy for it. Many critics on here mention that some of the characters can often be mean, manipulative and perhaps unlikeable, and in some case those critics are correct; and they are also completely missing the point. Look deeper... Orphan Black doesn't attempt to portray these women are the perfect embodiment of their sex, but as real beings who are flawed, make bad choices and worse mistakes. Although these are strong diverse women, they can be selfish, self-absorbed and vulnerable; all is on display. It may be solid sci-fi, but the science is secondary to what the show is about and that is what it means to be a family. It is about motherhood, sisterhood and a woman's right to her own body, in this case literally. It is about a woman's place in society and the debate on nature vs nurture. Indeed, feminism is strong throughout this show, but it is never overly overt, or to the detriment of its strong male support. Orphan Black successfully demonstrates that masculinity should not be the continual attempt of living up to toxic ideals, but that decent men support and respect those around them. However, Orphan Black never leans heavily towards an overly strong agenda and has an true equality to it that this world needs in these times. In my opinion it is hands down THE best TV series I have ever seen...period, and that is saying something for me. My only regret is that it took so long for me to get round to watching it. It's now been 3 weeks since I watch the entire volume and I miss it already.

I watched the first 3 seasons then tossed it aside when I lost patience waiting for the release of season 4. Now I just finished season 4 but I'm not particularly impressed. The first 2 seasons had a more clever plot and the Sarah character was better acted out. On the third season we see the quality starting to slip. The show starts to drag a little and Sarah sometimes suddenly freaks out with insufficient context, and by that I mean she seems a weaker and more temperamental character than she seemed in the first 2 seasons, and there wasn't a gradual change to explain that, it just started pretty soon after the start of season 3, turns out they had a whole bunch of producers and had adjustments to staff every season, maybe that explains it. I remember more of the season I just watched so I can give some more examples about the quality of the plot. When Cosima finished her research and got locked out of the computer, she went without any precautions to approach Susan when she was having a call, and consequently got locked up, why? She was sick, half dead, and she would approach Susan, somebody who plotted against her, unarmed and unprepared? What on earth was she hoping to achieve besides getting herself locked up or even worse?? When Sarah put down her gun when approaching the wounded Susan I immediately suspected something was wrong, it was stupid and careless of her, and her running away from a crippled Rachel instead of kicking her hard and repeatedly with her good leg was pretty unconvincing. Right after that, S and Kira got caught by Ferdinand, which happened because they chose to stay at a compromised location instead of the safehouse, which was in fact left empty at the time except maybe Krystal was still there? Also, the science is far from sound...a gamete from one set of genome of a chimera with a gamete from the other...always makes half of the chimera, not the whole two sets. It's not gonna save anybody, or if you make 5 sets of those statistically you should have ~97% of the whole genome and you could just pray that the cure isn't in the other 3%? Morally speaking, the whole idea of this series is also just another naïve smear on eugenics. Some people go on blabbering about "you don't know what perfection is" or something about diversity being absolutely and indisputably good, then why are there mitochondria treatments? The simple truth here is that without the treatment there will be no viable offspring, but the treatment is already a part of eugenics, because one set of mitochondria DNA is designated "good" and another "bad", and the "good" is used to replace the "bad", so here these people stop arguing about "diversity". From here there's no fundamental difference from treating any other hereditary diseases. I argue for free will, people should be allowed to alter their DNA to their free will, if their choices result in "conformity" and not diversity, then it's just where we're lead to.

I've watched all 5 seasons. Season 1 says "this is great, keep watching it". Season 2 says "Just wait, it will be better". Season 3 says "Ha, you thought this will be good?" Season 4 says "We don't know what we are doing with this show" Season 5 says "Ok guys, just finish this crap, ok?"Too much nonsence scenes, too much questions, too much stupid outlines. I was expecting serious SCI-FI reading those comments ,and the most SCI-FI thing i've seen on this show, was only a stupid tail that had some guy. Wow.

All you gotta know is that this show is a masterpiece.
