Do we need another hero?

Heros; do they play a constructive role for us today or are they just wasteful distractions?
When you consider the prevalence of heroes through out time we have to acknowledge there seems to be an inherent need for them in our psyche.
Do they provide us with an inspiration to overcome our own obstacles? Are they a role model for us to achieve greatness in our own lives? Do they provide hope when all else seems lost?
