You do get the very distinct idea that healthcare provision has declined somewhat in this dystopian future.
The defining character, though, is the barren and unforgiving landscape which provides the purpose and drive for the movie.
Although some of the human characters are difficult to connect with and understand, the vast expanse of the desert is a hammering constant that supports the relentlessness of the action and harsh realities of the film's themes.
The visuals are divine, and the gorgeous aesthetic is somewhat reminiscent of Jim Henson's The Dark Crystal, complete with landstalkers and Skeksis, riding on motorcycles. With grenades. And miniguns.
The soundtrack is fantastic, and the stand-out supporting character has to be the insane flame-throwing guitarist, chained to the front of an eight-wheel juggernaut, complete with enormous resonating drums. Fantastic.
