People talks a lot about Black Mirror here and there so i gave it a try. I watched this series with expectations of some mine bending stories but i was disappointed to see only one or two episodes out of 22 episodes consider as "mind bending" stories. The main motive behind the series is how technology can change the world in both way, good and bad. If you are going to watch with high expectations then give it some time to adjust according to your expectations and you would probably don't like first season then. For me 4th Season is the best one in entire Black Mirror Seasons but hey, don't go and watch directly 4th season because as i said give it some time to adjust accordingly.
