In this film, the development of the character Stefan and the plot of his story is dictated by viewer choices, allowing for multiple endings. Stefan is a game creator, designing a game based on the choose your own adventure book, Bandersnatch. The book itself is a symbol for madness, as the author of it himself is insane, having murdered his family and himself because of his obsession with his work. In one of the endings, Stefan himself also follows the same fate of Bandersnatchs author. However, it is curious how he ends up on such a path. The viewer has to selectively choose paths that cut Stefan off from the world, as if Stefan was indeed paranoid. He himself fears his therapist, his father, and his coworkers, so by choosing to remove him from society, his paranoia erupts into the forefront of his mind, creating hallucinations and stressing his mental state to the point of literal insanity.  What is interesting however, is that this theme is similarly present in much of the gothic literature we have read for this unit. Paranoia is developed, grown, and ultimately becomes the main motivation of action and tho", "g");
