(FILM) A straightforward—which is to say, turbulent and vertiginous—recounting of one of several "events" of September 11, 2001, United 93 is a fascinating movie. It's about heroism, but it offers no heroic characters. It's about chaos, but it's rigorously structured. It's based on a narrative encumbered with the grandeur of myth, but the screenplay is astonishingly quiet: more like the outline for a story than an already inked annal of history.
