I suspect a big part of this, outside of Miller being an action veteran who's a genius at his craft, is the amount of planning that went into it. Instead of a script, Miller storyboarded the entire movie, and that was over 10 years ago.
He's been living this story so long I suspect, he knows every single inch of every edit by heart. This is backed up by the fact his original intent was to film the entire movie, including all the stunt sequences, with just a single camera, which is bonkers crazy when you're talking about stunts that cost millions of dollars. No multi-cam stuff, he knew exactly what angle he wanted for every single shot, and it shows. Now, in practice, that didn't quite end up happening (his cinematographer wouldn't stand for it and snuck additional angles in there for safety), but it gives you an idea of how much thought went into this.
This does truly ruin all other action movies. Like, I'd rather re-watch Fury Road every weekend for the next 2 months instead of seeing whatever new movie comes out, because nothing else is going to measure up.
