Why do people think things like the Bechdel test are worth more than a fart in the breeze
A test is just providing some objective information about something.
What you do with that is your business.
The Bechdel test was presumably invented to identify movies that fail the Bechdel test as deficient, problematic, etc.
But the test can just as easily be interpreted the other way. Netflix might someday soon come up with a category called "Bechdel Failures" and learn that it is extremely popular with men.
I think it would be great if there was some kind of logo or something that indicated if a movie passed or failed the Bechdel test; feminists could look for passing films, and I could look for failing films.
