During the widespread COVID lockdowns of 2020, dozens of Americans decided to learn something new in their spare time, by taking up sourdough baking, woodworking or birdwatching. Many have also turned to documentaries to stimulate their minds. The documentaries were, in fact, the the fastest growing genre on streaming platforms in 2020.

The age of streaming has made non-fiction films more popular – and lucrative – than ever before. Documentaries have become more accessible to the public, and streaming platforms and production houses are putting more and more more money in films such as true-crime documentary series, celebrity biographies and cult exhibitses. (Similar topics are also fictional, of course – not always successfully. Here are the 50 worst movies based on true events.)
