I'm pleased that Hollywood hasn't tried to exploit the Mad Max franchise like they have so many others, with sequel after sequel, ruining it in the process.
It certainly has cash cow potential. It's a great storyline and the "universe" provides possibilities for easy story writing.
Fury Road was a good film, an entertaining action flick. Who doesn't like a good chase scene...well that's the plot.
As for Theron in her "most unglamorous role of her career", have you seen Monster..? *Shudders*
