But Stone chose to dig deeper. Most of the movie focuses on the two policemen, McLoughlin and Will Jimeno (played by Michael Pena, and here let's also recognize the heart-wrenching performance of Maggie Gyllenhaal as his wife, Allison), pinned under the devastation, with only their dusty faces partially visible, talking to each other, using their voices and their words as the only instruments available in their darkened tomb to keep each other alive, as their crushed bodies slowly seek surrender from the physical agony of countless injuries.

What keeps them alive are the very footers of civilized society that our cynical, enlightened popular culture is seemingly so desperate to discard: fraternal love, devotion to family, allegiance to country and faith in God. Each element is powerfully developed, not just in the officers' dialogue, but also in the cutaways to the battered co-workers and the two anguished families anxiously praying for a miracle, in the quiet resolve of the former Marine who dons his uniform and enters Ground Zero, ultimately to make the discovery, and most poignantly in Jimeno's visions as he teeters on the brink of death. A Catholic, Jimeno sees not an ambiguous Hollywood representation of a higher power, but the sacred heart of Jesus. It is -- this being a true story, it was (END ITAL) -- these values that kept these two heroic policemen tethered to life.

You kept me alive. After 9/11, we pledged as a nation that this atrocity was something we would never forget. We declared that loudly on our bumper stickers, on our license plates, on our billboards and in our corporate advertisements -- a national "post-it" note on our collective conscience, as it were. Yet only five years later the fires of purpose, stoked by a nation's sorrow, rage and commitment to justice, are waning. For a brief moment after that fateful day, there was a sense of national unity unseen since the glory days of the Greatest Generation a half-century before. Now where are we?

"World Trade Center" pleads with us to remember that moment and to keep it alive. It is not appropriate for the very young, of course. It is appropriate, indeed necessary, for everyone else, just as it is appropriate, and necessary, for Stone's critics now to salute him, and thank him for the gift he's given his country.
