What I enjoy about "Black Mirror" is that many of the episodes look at modern technology and anticipate their potential abuses and down-sides. In this case, the notion of being a helicopter parent is taken to an amazing level...thanks to tracking software and iPad-like devices.
The story begins with a baby being born and all seems well. But when the little girl later walks off and the mom is panicked, she picks an unusual way to protect her child...she has a chip installed in her called 'Arkangel' and it tracks her. But the chip can do much more. It can actually filter out negative images and content...and the mother decides to use this as well. So, instead of seeing blood and violence and bad behavior, the child just sees pixilated images and cannot hear the awfulness. Sounds like a great idea, huh? Well...as the child grows, it's like having NSA inside her head...and the repercussions are awful.
The most interesting thing about this story is that it was directed by Jodie Foster (yes, THAT Jodie Foster). This, along with some impressive location shoots in ensuing episodes shows that this show has found an audience! As for this particular episode, while it's not among the best, it is quite disturbing and well made....and well worth your time.
