It also had, for the most part, terrible acting and terrible dialogue. As in, despite the quality of the action, I felt embarrassed to have suggested that me and my friend go and see it, they were so bad. If fire and fast cars is all you need to consider a movie brilliant, whatever. I need more than that.
I think it really depends on what grounds you judge the movie. I judge it as a blockbuster action movie and on those grounds I thought it was brilliant. Does that mean it's a flawless film? It's not a movie I would put up there among my favorites of all time, and it's not the kind of movie you could compare to deep philosophical films, but compared to most other big blockbuster action films, it definitely stood out as one of the better ones in recent memory. But that doesn't mean it should be compared to Citizen Kane or anything like that.
Personally, while I watch many of the big blockbuster movies, those are very rarely among my favorites overall. There's a few exceptions like The Matrix or Terminator 2 (both being big films, both being in my top20 films of all time), but my favorite movie of 2013 was Her, that was an indie film. My favorite film of last year was Whiplash, that was an indie film. Drive was my favorite film of 2011 (?) and that was also an indie film. Those kind of films tend to stick with me more than the big blockbuster ones, but you get surprised sometimes.
As for the Mad Max series, I'd still probably rate Road Warrior at nr1, but Fury Road is a close second.
