It's fine to have a documentary that shows various extreme types of "play", but the show creator decided they would make up reasons why we do it. Clearly the writers do not have the expertise to provide any insight into this. Ridiculous. One example is saying we do scary things to "maintain alpha status". There is no such thing as "alpha", except in some internet bros' minds. It's neither a scientific term, nor is it a widely-used layman's term. Another example is saying something about how 200 years ago, we all faced death or did scary things regularly, not as play, but as a necessity of daily life. Such a blanket statement is completely wrong. Most human societies have been stable for long periods. Having regularly scary activities would happen in some times and some places, but was by no means universal. As far as anthropologists know, that would have been true for 10s if not 100s of years. About the only regular scary thing would be hunting large, aggressive game, but doing so is definitely not universal.
To the writers: Next time, stick with just the sensational activities you're showing and leaving the made-believe "insight" on the drawing floor.
