I'd say he is more like Clint Eastwood's "Man with No Name". The story itself revolves around others (like the town needing to escape the bad guys in Mad Max 2) but it is Max (and Clint) that is central to the action of achieving that aim. Yes, there are other strong characters in those earlier movies, but I'd argue Max was far more central then than in Fury Road, which I did like very much. I just really need much more Max.
That would result in a different story though. Max has the appropriate amount of presence that the story needs of him in
Fury Road. In
Mad Max 2 the people Max helps aren't really the toughest - the contrast between Humongous' pack of killers and Papa Gallo's community is pretty stark - so Max ends up doing most of the legwork. In
Fury Road most of the characters are a lot more battle hardend, and there's a greater sense of war, and because of that Max doesn't feel like the one true badass. But even then, he's a major drive throughout
Fury Road - the wild card that sets a lot in motion - and is pretty much the star of the climax.
