"Bandersnatch" is a special interactive "Black Mirror" episode that aired in 2018. It stars Fionn Whitehead as a young programmer named Stefan whose game is picked up by a major studio owned by big-shot designer Colin Ritman, played by Will Poulter. Eventually, Stefan begins to feel like he's being controlled by outside forces — almost like he himself is a character in a video game.
The episode is exceptional thanks to its choose-your-own-adventure format, which prompts viewers to make choices about the story's direction via options that pop up onscreen. While mind-bendingly meta, "Bandersnatch" also offers emotional notes that draw it all together and make it one of the most unique episodes of television out there.
