There are obviously some stories out there that don’t lend themselves to much female representation on screen (for example, a historical drama following an all-male platoon of soldiers or a movie that centers almost exclusively on one character like Cast Away) so the Bechdel test is more useful as an aggregate tool for assessing the state of the film industry as a whole than for judging the quality of any one film in isolation.
It’s still bananas that there were six consecutive Star Wars movies that failed the Bechdel test though. I can’t even remember a single named female character who wasn’t a relative of Luke Skywalker. (Mon Mothma doesn’t count because her name was never mentioned on screen and she had less than 30 seconds of screen time anyway.)
