Tom Hiddleston, who is reprising his role as Loki in The Avengers, has published a passionate statement defending superhero films, and explaining why we should take them more seriously than we do.
"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."
I really encourage you to read the entire thing
It's a great piece of writing and is very interesting, and particularly relevant to modern day cinema.
