Black Mirror: Fifteen Million Merits (2012)

There are two series and the episodes all have different stories and concepts, but they are all similarly bleak and dystopian alternate reality pieces.

The episode you're watching now is probably my favourite but the others are fantastic too, especially the one with the memory implants.

As Charlie Brooker (creator) put it himself, these are potential futures if society were to take a couple of steps in the wrong direction.
