It was awesome. I went in expecting hardcore action and kickass ladies, but I got so much more.
Yes, it has one long action scene at the start, a somewhat calm middle, and then another long action scene at the end, but somehow it manages to tell an interesting story throughout. It doesn't make any sense when I say it, it has to be seen to be understood.
The movie is surprisingly sympathetic towards its characters. They're complex and develop naturally. Even the psychotic War Boys who dream of dying violently in battle have proper backstories that make them more sympathetic, even if we can't forgive their behavior.
It's very much a "show, don't tell" movie though. They don't tell us the war boys are just misguided and ignorant little kids who have been brainwashed by Joe. They show us the war pups as they are before they become war boys, and how desperate the war boys are for Joe's attention.
The five wives aren't just five identical women. They have personalities, stories, and skills that make them stand out from each other. They are victims of rape, but aren't shown as victims. They're shown as survivors. They can't fight like Furiosa, but they participate and help her and Max as good as they can (You are going to love them for pulling Max's chain).
Max is indeed mad, and doesn't magically turn sane at the end of the movie, though it helps him to have a purpose. He only grunts and gesticulate in the beginning, but slowly starts to talk more as Furiosa helps him to focus and not get too lost in his own head.
If that sort of thing interests you, it's also worth mentioning that Furiosa and Max's relationship isn't sexual, but very femdom'y non the less. She's very calm and has an air of power around her which Max responds to. She doesn't have to yell or bark orders at him, he knows she's better than him and does as he's told without question (after he starts to trust her, that is). This obviously isn't the standard dynamic between men and women in this universe (just look at Nux and Capable together, who are adorable btw) but it's the most natural thing for Furiosa and Max. They're both badasses, respect each other, and they both benefits from this dynamic (She gets the help of a tough guy, and he gets a clearer head when she tells him what to do). And I'm far from the only one who picked up on this. If you look up Furiosa/Max fanfiction you'll notice every single one has some level of femdom. I'm not pretending Mad Max is a femdom movie, but it follows a lot of femdom tropes (The scene where Max acts as Furiosa's rifle stand is the most obvious).
So yeah, if you actually care to pay attention to anything other than the explosions (which are awesome) Mad Max Fury Road is so much more than just action and violence. It comments on things like how young men are expected to kill themselves for the greater good, how women are treated as things, how we can all be blinded by fanatical religion if we're born into the wrong crowd, and so on.
Or in other words, I cried three times while watching it. I didn't expect that.
