The movie's ridiculous presentation hides its fairly sophisticated inner workings. I'm not claiming it's high art, but it's not just pure stupid action a la Transformers or something. There is a lot of interesting storytelling happening just through careful attention to detail, and it's almost a case study in "show, don't tell"*. For example, we know a lot more about Furiosa than you'd expect. She's a capo in this horrific, misogynistic tyrant's society. Towards the end of the film, Max asks her what she's hoping for and she just answers "Redemption". The look in her eye tells us the rest. These little pieces are deliberately placed - we don't know the exact details of how she went from kidnapped slave girl to commander in the Immortan's forces, but we can figure out enough of it.

Or, let's look at Max's changes throughout the movie. He starts off deranged, disheveled, covered in matted hair - feral, in a word. Then he's captured and literally caged. He's got a muzzle on for the first third of the movie! He gets free, lashes out, and is slowly tamed by Furiosa and the other women. Ultimately he ends up helping two generations of women fight back against the tyrant who ruined their collective lives. I don't want to say that this has a direct meaning (something like "oh he's learning how to shed toxic masculinity and be a better ally!), since I think that literal interpretations tend to detract from emotional depth. Themes in story are best when they're expressing feeling and not a literal message. There is a lot going on with gender conflict. From the repeated "Who killed the world?!", to the obvious level of the wives fleeing the big gross dude, the one war boy slowly realizing he's just another foot soldier for a man who doesn't care about him, to the greater susceptibility of men to follow dangerous men to destructive ends while women seem more resistant to that.

Come to think of it, Fury Road is best compared to Chainsaw Man. The manga and anime are about a lot of things - the struggles of growing up poor in Japan's lost generation, a government that explicitly views you as an animal to be used for their own ends, the corrosive nature of workplace politics, cynical sexuality used for manipulation, and more. It's also about a man who is a fucking chainsaw. Ridiculous, over-the-top action serving as the capstone to a carefully planned world and story.

*I happen to think that "Show, don't tell" is overused as storytelling advice, but the execution here is flawless.
