But superhero films offer a shared, faithless, modern mythology, through which these truths can be explored. In our increasingly secular society, with so many disparate gods and different faiths, superhero films present a unique canvas upon which our shared hopes, dreams and apocalyptic nightmares can be projected and played out. Ancient societies had anthropomorphic gods: a huge pantheon expanding into centuries of dynastic drama; fathers and sons, martyred heroes, star-crossed lovers, the deaths of kings – stories that taught us of the danger of hubris and the primacy of humility. It's the everyday stuff of every man's life, and we love it. It sounds cliched, but superheroes can be lonely, vain, arrogant and proud. Often they overcome these human frailties for the greater good. The possibility of redemption is right around the corner, but we have to earn it.
The Hulk is the perfect metaphor for our fear of anger; its destructive consequences, its consuming fire. There's not a soul on this earth who hasn't wanted to "Hulk smash" something in their lives. And when the heat of rage cools, all that we are left with is shame and regret. Bruce Banner, the Hulk's humble alter ego, is as appalled by his anger as we are. That other superhero Bruce – Wayne – is the superhero-Hamlet: a brooding soul, misunderstood, alone, for ever condemned to avenge the unjust murder of his parents. Captain America is a poster boy for martial heroism in military combat: the natural leader, the war hero. Spider-Man is the eternal adolescent – Peter Parker's arachnid counterpart is an embodiment of his best-kept secret – his independent thought and power.
