One TV show that is often praised for its use of an unreliable narrator is "Mr. Robot." The protagonist, Elliot Alderson, is a hacker with mental health issues, leading to a distorted and unreliable perspective on the events that unfold in the series. This impacts the story by keeping the audience on edge, questioning the validity of the events portrayed and creating a sense of unease and mystery throughout the show. The unreliable narrator adds layers of complexity and intrigue to the narrative, making it a compelling viewing experience.
