I'm not going to delve into all that crap, because frankly people are just being dicks but that's nothing new.
However, there's two things that really set this movie apart for me.
First is the world building. The movie gets straight into things, a quick monologue to set the scene then away it goes. From there it introduces many, many bits of the world itself as it goes, without resorting to flashbacks, or exposition and the like. It trusts that you will just take it on its word that these people do this, by showing you. There's no "oh no, the canyon, the bike dudes in there will hate us because of x/y/z", its just "ok there's bike dudes shooting us now". I love it when a movie does this, another good recent example would be John Wick.
Second is the usage of actual physical vehicular stunts. The movie looks good, seamless so to speak. This was rammed home to me during one of their publicity stunts where they had a lot of the movies vehicles driven through downtown sydney, with actors in the costumes from the movie. It looks surreal. However, the movie looked exactly the same (except in a desert), something like that you can't do if you've made everything up with CGI.
There is a second string to this, as the first movie (although a different type of movie, really) was what launched the Australian film industry up a notch. I recall an interview with one of the stuntmen about the stunt where a car is driven through a caravan. How did they do it? They got a caravan, a ramp, and drove through it without really knowing how it'd end up. The industry though is now a more permanent fixture, the cars for the movie made in Australia as far as i know.
