Movies with Post-Apocalyptic Mood

In a world where heroes are worshipped and mutant beasts are feared, I was cast out of the shelter—discarded as worthless for not being a hero.But by sheer chance, I gained the power to control the life and death of those beasts.So I set up a supply outpost beyond the walls, dealing in the crystals harvested from within them.In this apocalypse, I play by my own rules—and rise to the top.Heroes? So what.Even S-ranks end up working for me.
