Column: What the 'Glass Explorer' reviews taught us so far

In the first season finale of the brilliant British TV sci-fi anthology “Black Mirror,” the story is set in a world where the majority of the public have high-tech "grains" implanted behind their ears.

These grains allow people to record every waking moment of their lives. Footage can be privately replayed within their field of vision or publicly projected as a floating screen called a "re-do."

The scenarios that result in this fictional world don't seem at all farfetched: Business meetings are reviewed and obsessed over, a night out at a club is replayed for ambience at a party, a couple in the midst of a fight replays what the person just said to gain the upper hand.

But this is a world without a single shred of privacy.

If you're within someone's eyeline, you're undoubtedly being recorded.

Intimate moments between former lovers are saved and replayed like a sex tape that just won't go away. Spotting a mate's furtive glance to someone else can be analyzed like the Zapruder film, picking up every subtle nuance of emotion and adulterous motive.

Even a character who elected to have her "grain" removed is looked upon like an oddity, a societal leper. It's a world where, potentially decades prior, everyone saw the possibility to have their entire lives exposed and said, "You know what? We're cool with it."
