Black Mirror: Ranking Every Episode From Worst To Best

How would your life be affected if you had an implant that turned your head into an Ipod, saving your memories into easily-accessible files to play back later? That’s the question The Entire History of You poses.

Because this is Black Mirror, this episode takes this potentially helpful invention and demonstrates how it could totally wreck your life – as it follows protagonist Liam becoming so obsessed with the past that he forgets to live in the now.

Written by Peep Show creator Jesse Armstrong, what's interesting about this one is that it focusses on personal relationships over the more sociological edge of other episodes. If you would like to see the premise explored in a fuller way, you’re in luck – none other than Robert Downey Jr. has bought the rights to make a movie version.
