Ok so, this story is all about an over protective mother, who since the beggining is shown how scared she is that her little girl gets hurt in anyway , her mother is way too f-up . AND i love it! It's realistic, there are real overprotective parents all around the world and that's ot the kids fault ,its the parents where they invade their childs privacy.the mother doesn't let her daughter make her own mistakes ( cause well thats called evolving amd learning) and ultimately makes her child have issues ( as is shown in the chapter as how she wants to see and taste and touch everything, cause for so long it was denied to her) leading up to a perfect ending, where you can see the value of this episode " if you pull too hard on a leash, it will eventually break"

It shouldn't be part of Black Mirror. The ending sucks.

Perhaps the reason this episode of 'Black Mirror' fails for a lot of viewers is because it's possibly the one that comes closest to examining a technology that could actually exist today. Let's face it, the ubiquitous cell phone with it's ability to take pictures and record what's happening in real time has changed the lives of everyone using it, some for better and some for worse. In the case of 'Arkangel', an implant of some sort provides a masking ability as well, so that unpleasant or troubling images can be blurred to the recipient of the implant. It wasn't really made clear in the story why the Arkangel project was banned, but one suspects it would be for it's invasive impact on the subjects being supervised. A very creepy affair when a someone can dial into a sexual encounter or view illegal drug use about to occur. And as always, unintended consequences can often intrude to derail one's life without any apparent warning. For once, this is a Black Mirror episode that could actually take place.

Once the overprotective mother has an implant installed, she has set things in motion that can only get worse. Sara, in an opening scene, chases after a cat and her mother becomes obsessed with protecting her. She has kind of iPad that can be used to check her heart rhythms, her nutrition, and most of all, what she sees. The kicker is a device that blocks anything that may be traumatic, so the girl grows to adolescence having a totally sheltered life. When the plug is pulled, she begins to experiment like crazy with her peers. Soon the mother resurrects the device with horrible consequences. The episode is really hard to watch. The mother is really the central character in that she can never accept her daughter being on her own.
