Black Mirror is known for making the viewer feel uncomfortable with the story. This episode, however, pushes suspension of disbelief too far in order to provoke that feeling; the woman doesn't remember who she was, and she's portrayed as a rather likeable person. This gives the "punishment show" a whole new connotation, since she's a completely different person from the one that committed the crime. And that's just ignored by the screenplay.
