The obvious way to show everyone what's happening in a fight is to train the hell out of the actors and do it all in one shot. And unless you're a total asshole, you just thought of Oldboy or the Daredevil prison scene or the time Tony Jaa went into a building looking for his elephant and kicked the fuck out of every man and furnishing that wasn't it. But the example I want to talk about is the fight between Max and Furiosa in Fury Road.
There's an absurd number of things happening in that scene. There are six different weapons being fought over by eight people, and two of them are chained together. The momentum swings back and forth 12 times, and it's always clear who's winning and why. But maybe the most impressive thing is how it's never ridiculous that a man with triple the muscle mass and twice the arms of his opponent is having a tough time. It's a perfect sequence from a perfect movie, and I'll defend that statement with a car door on the end of an intravenous chain.
Now I want to talk about a bad example, and the dumb shit that led to it. In the last 20 or so years, there's been a trend in action movies to make fights look more "realistic." No one will ever agree on what exactly that means, but filmmakers sort of decided it was two guys deliberately bashing their wrists together. Instead of haymakers and spin kicks, they started focusing on no-nonsense fighting arts like Krav Maga or Arnis or Telling Dave Bautista that Daniel Craig is Filled with Delicious Candy. These styles seem brutal and effective, but they've suspiciously never been adopted by any professional fighters, alive or dead. What I'm saying is most "no-nonsense" martial arts are tested only in the crucible of some nerd's imagination, which made one of them perfect for the official fighting style of The Batman.
For Batman's gritty and intense combat, Christopher Nolan chose the Keysi Fighting Method, a martial art designed mainly to protect your skull as you trash a bar. In KFM, you keep your elbows up and maniacally bash, similar to how a chimpanzee might escape a car and change its T-shirt at the same time. It's since been abandoned by the guys who developed it, but KFM is the reason Batman looks like he's auditioning for Paula Abdul when he fights. Combine this with darkness and frantic handheld shots, and you have three movies where no one can tell what the fuck Bruce Wayne is doing.
