The Internet can be a scary place in real life, and far more so in Jane Schoenbrun’s film “We’re All Going to the World’s Fair,” which premièred at the Sundance Film Festival last year and is being released in theatres and streaming. It’s a horror movie centered on a lonely and bored teen-age girl named Casey, who spends most of her time being online and trying to figure out who she is. She undertakes a ritual that she’s read about—the so-called World’s Fair Challenge—which is said to cause unknown and possibly dire changes. “Everyone wants to know, ‘Do you think the Internet is good or the Internet is bad?’ ” Schoenbrun told the Radio Hour’s Alex Barron. “That’s like asking, ‘Do you think that people are good or bad?’ There’s not a simple answer.” They spoke about the forty-year history of movies depicting the online world.
