I've tried reading the book several times; I feel that the problem isn't so much that the content is intrinsically difficult, but rather that the style of writing is generally terrible. Paragraphs are spent on something that could have been expressed in a sentence, and every now and then one gets the feeling that the book is written using English vocabulary and German sentence structure. A good editor could have cut down the length by hundreds of pages without losing anything essential.

The content is great if you can work your way through it, but despite that, I've still never managed to work my way through the whole book.
