I am reading so many things right now I'm not sure if I can squeeze in Point Omega.
I didn't like Cosmopolis, the last one of his that I read. When I like DeLillo, he's making the world seem more real than it normally does to me: White Noise, parts of Underworld. Cosmopolis suffered from, I think, its head-on confrontation with a city that has resisted the Joycean program ever since imitators started trying to Ulysses-ize New York.
I suppose I should give Omega a chance. I fear polemic on the Iraq War and the right wing, both targets deserving of as sharp a critique as we can muster.
