First of all, a quick comment about the casting of Bruce Willis as a man who discovers that he is -- for reasons unknown -- far less prone to injury than the average person. Or even the above average person. Or even Arnold Schwarzenegger.
Okay, now think about the "Die Hard" movies and everything John McClane experiences and survives.
Just a thought, folks.
I really like this movie's unique way of taking the "superpower" concept and examining it in a gritty, real-world manner. Not only is the concept brilliant and fascinating, M. Night Shyamalan's think-outside-the-box style of directing is without equal. He presents story elements in a manner like no other director ever has -- or at least not in the same frequent and consistent degree.
The internal struggle which Bruce Willis' character experiences while trying to accept his special physical nature is completely devoid of the typical (beloved) Hollywood heroism. He doesn't make speeches about the great responsibility that comes with great power, he doesn't square his shoulders and preach about his duty to mankind.
He just silently submits to the moral imperative of delivering justice when faced with monumental injustice.
And yet, even the grim struggle between Willis and the unnamed murderer/rapist in the climax is absolutely devoid of any flashy fighting techniques, incredible stunts, or shocking final death blows delivered to the villain.
I'm tempted to say that the battle is a metaphor for what we all face in real life -- the frustrating and protracted struggle we endure daily as we meet the challenges of life, desperately hoping they won't defeat us.
Naw, that's too intellectual. Let's just say it was a great way to present a climactic battle in a different kind of superhero movie.
PS: I wonder what the M stands for.
