Someone doesn’t like Against the Day:
Thomas Pynchon’s new novel, “Against the Day,” reads like the sort of imitation of a Thomas Pynchon novel that a dogged but ungainly fan of this author’s might have written on quaaludes.
But she often gets her panties in wad, right? Here’s another take on it. And another. I’ll have to obtain a copy and see for myself, which will take a while, the obtaining and the seeing both.

Michiko Kakutani has been called the “Iron Dragon Lady” of book reviews and her position as one of the top New York Times book reviewers (alongside the likes of A. O. Scott) is pretty much undisputed in terms of the authority of her taste, and the influence she has on the literary community. She usually crucifies what she hates and lauds what she loves (who doesn’t, right?), but she does it with such precision and merciless insight that it’s often hard to argue with her. I use her largely for books she praises (since I tend to often like books other people hate). If she loves a book, it’s probably destined for immortality. If she hates a book, well it’s just because she has a tiny bookshelf and no room for nothing new.
Basically, yes you should read it for yourself (as I intend to).
