Falling Man--Don DeLillo

I think DeLillo isn't at the top of his game with Falling Man, which pains me as a DeLillophile (and thus frequent apologist). Plot summary: a couple struggles to make sense of 9/11, cut three years, they are better, but still messed up. The title falling man is but a small part, as are the disjointed scenes fictionalizing the radical conversion of Mohammed Atta. The elements of what DeLillo does well are still evident here--scenes of dense imagery that leave you breathless (the last few pages are particularly brilliant)--but the plot doesn't really go anywhere. Perhaps the lack of plot direction is intended to reflect that as a society we still lack focus and consensus about the meaning of 9/11, but maybe I'm giving DeLillo too much credit and it's just an unfocused novel.
