About the ending...(SPOILERS)
Methinks that, in the end, Max was right about distrusting or disliking the people he helped, because they cheated him with the gasoline. They used Max as a way to escape from the punks/savages. His resentment or anger seemed to have a point, anyway.
I think he only respected or had a little sympathy for the Gyro Captain, although in the few last scenes.
Best action film i've ever seen, with an unforgettable ending.
