It’s worthwhile comparing the criticism to other works such as James Joyce’s Ulyssess. Take this quote from a review in the NYT:

Few intuitive, sensitive visionaries may understand and comprehend "Ulysses," James Joyce's new and mammoth volume, without going through a course of training or instruction, but the average intelligent reader will glean little or nothing from it- even from careful perusal, one might properly say study, of it- save bewilderment and a sense of disgust. It should be companioned with a key and a glossary like the Berlitz books. Then the attentive and diligent reader would eventually get some comprehension of Mr. Joyce's message.
