In January 2015 the humourist Mallory Ortberg summed up Charlie Brooker’s tech-anthology series Black Mirror as “What if phones, but more so?”. The science fiction show focuses on how high technology and low entertainment can magnify our flaws and destroy our relationships.

We greet innovation with open arms, says Brooker, only to find ourselves embracing disaster. But among the cynicism, one episode offers a more optimistic outlook, and that is two-time Emmy winner San Junipero.

The episode was hailed as a classic immediately for the way that it combines Black Mirror’s trademark futuristic vision with a beautifully told love story. And, unique in Black Mirror history, it offers a happy ending. Here, the machine that gives the story its science-fiction edge doesn’t destroy our humanity; it offers a sort of mechanical heaven for its users.
