Some of the footage I saw around SDCC Time looked fantastic!
I hope it is. The trailer looks awesome. As long as they've stuck to the "Max style" it should be okay.
If you recall at the end of MM he drives out into the wastelands and in the beginning of MM2 it is mentioned he'd done so so this new film fits in that regard and Tom Hardy's age fits as well.
In the novels it is mentioned that people begin to abandon the cities and move to coastal towns and inland (wasteland) because the cities have become violent hotspots and when the bombs fall the cities cop it HARD. The novels delve deeper into the worldwide issues that the films just breezed over.
