I have only read the beginning of the script so far, but for example the part about Vincent being there, on the street outside, as the plane hits the world trade center seems to be a kind of literary usury, that is that it is clearly attempting to be gripping simply through fantastic plot twists etc... If the reality and repercussions of that "chance" event in Vincents life are woven into the script in some kind of real way I take it back. It would work better as a backdrop that would affect the story: as the reason Vincent leaves New York at a certain point; some killings happen in the kaos; a boardroom meeting between Vincent and business associates gets broken up in Manhatten because of it at the same time, would be more believable to me.
