Netflix explains, “We worked with Keaton Patti to make a bot watch over 400,000 hours of horror movies and then write its own horror movie. This is what it came up with.”
The result is the 4-minute “First Horror Movie Written Entirely By Bots” video, a very Saw-like horror movie centered on Mr. Puzzles, a villain who wears a devil mask and forces his victims into elaborate traps involving everything from chair saws to a deadly rollerblade canon.
Given this short film doesn't seem to show up on Netflix.com, and the YouTube channel it comes from is named "Netflix is a Joke", I'm 90% certain that either these news sites were duped in, or that they're entirely in on the joke, but it's possible that Netflix actually did work with Mr. Patti.
