Characterization
Some reviewers complain that Pynchon's characters have little emotional depth and therefore don't excite the sympathy of the reader. For example, Laura Miller in Salon.com:
Time doesn't exist, but it crushes us anyway; everyone could see World War I coming, but no one could stop it — those are two weighty paradoxes that hover over the action in "Against the Day" without truly engaging with it. This is the stuff of tragedy, but since the people it sort of happens to are flimsy constructions, we don't experience it as tragic. We just watch Pynchon point to it like bystanders watching the Chums of Chance's airship float by overhead.
New York Times reviewer Michiko Kakutani writes of the characterizations: "ecause these people are so flimsily delineated, their efforts to connect feel merely sentimental and contrived."
In some of the reviews to his previous works, Pynchon had been called a cold, lapidary writer. Poet L. E. Sissman, from The New Yorker, instead praised and defended him, saying
I do not find him to be one. Though his characters are not developed along conventional lines, they do, in their recalcitrant human oddity, live, and they do eventually touch the reader more than he at first thinks they will.
As a complement to Miller's criticism about tragedy, Adam Kirsch sees comedy as undercut as well, although parody remains:
The gaudy names Mr. Pynchon gives his characters are like pink slips, announcing their dismissal from the realm of human sympathy and concern. This contraction of the novel's scope makes impossible any genuine comedy, which depends on the observation of real human beings and their insurmountable, forgivable weaknesses. What replaces it is parody, whose target is language itself, and which operates by short-circuiting the discourses we usually take for granted. And it is as parody — in fact, a whole album of parodies — that Against the Day is most enjoyable.
