Not only was I not that fussed with Mad Max, I don't like a single other movie named by anyone in this thread so far, except Fight Club.
Mad Max had incredible action and effects, and I was fine with the plot and the way it progressed, though I think they blew their load before the finale. That last chase didn't have the spark that the earlier ones did.
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.
Also, you can try and justify Max as a "minimalistic" character, but I'll be fucked if I'll willingly sit through a movie twice in which the main character literally grunts like an ape in numerous scenes.
