Black mirror never fails to amaze me. I would like to point out the sheer irony of Arkangel- how it turned out that Arkangel was the reason the mother lost her daughter when all she wanted to do was never lose her child ever again after losing her in the park when she was a little kid.
Some of the things I really enjoyed in this show:
1. How the show portrayed the unjustified behavior of helicopter parenting. With the advancement of technology, imagine a world where your parents can monitor each and every activity of yours. Sounds like a nightmare, doesn't it? For a child to grow, it is really important to remove the filter of a happy and beautiful world. With hardships and emotional suffering, people grow and learn, and eventually become strong enough to deal with it.
2. How lack of communication between parents and children can be disastrous. At least, after a child becomes a teenager, I believe every parent should be "real" with their child and warn them about all the things out there. Being a teenager is an experimental age where children are trying to figure out what they want and what they like. It is a part of the learning process that shapes one into an individual in the long run. Being protective is good but being overprotective does more harm than good. The mother should have indirectly communicated with her child and should have made her feel comfortable sharing the things she did in the past as a teenager herself - basically establishing a healthy Mother-Daughter relationship.
However, there were certain things that I didn't particularly enjoy:
1. The girl who played Sarah didn't even look close to 15, so it was harder to sympathize with her.
2. Although after knowing that her privacy is invaded (Worst fear of a teenager), she was so desensitized that she left her mother in a semi-dead state. It didn't exactly add up considering she used to say phrases like - "Love you, mom", "You look hot" - when her mother was supposedly going on a date. It showed that she used to care but suddenly all of it was all gone, and that too, to such an extend that she attacked her own mother.
