15 Most Disturbing Black Mirror Moments

15. Ash Goes Into Storage

Be Right Back had subtle yet disturbing implications, as it dealt with the prospect of bereavement in vintage Black Mirror style.

Martha attempts to fill in the void of boyfriend Ash's untimely death by investing in a robot facsimile of him, with his personality traits based solely on his real-life counterpart's past social media posts. It's fairly easy to imagine where it goes from here. Robot Ash looks and feels like the real deal, but only up to a certain point. He's more of a deadpan knock-off, lacking in any real soul found in the original.

Because of her choice, Martha is unable to move on from the death of her boyfriend in any tangible sense, nor is she able to dispose of the docile, mind-numbly obedient clone. She is left only to store him in the attic of her house, much like an old photograph they both made reference to at the beginning of the episode.

Her attempt at recapturing the past instead turns into an itch she cannot scratch, and makes for a frustrating and highly unsettling problem during her future years.
