Filmmaker Ric Burns adds a poignant postscript to his series "New York: A Documentary Film" with this chronicle of the World Trade Center's rise and fall. Burns recounts Sept. 11 wrenchingly, but he devotes more than half the film to the Center's rise. This isn't a pretty story: It's one of economic, political, architectural and engineering labyrinths. The result was a critical and commercial flop, though historian Kenneth Jackson says: "It's more important to history now that it's gone."
