The premise of Jane Schoenbrun’s debut narrative feature We’re All Going to the World’s Fair is familiar on the surface: An isolated teenage girl uploads a video on online participating in the viral “World’s Fair Challenge,” wherein one pricks their finger, smears their own blood on their computer screen, and announces “I want to go to the World’s Fair” three times before then watching a video of flashing lights growing more and more rapid before abruptly ending. What happens next to the participant is up to them to document, and the MMORPG horror game begins.
