Query: Difficult to read, not much positive

The author spends an enormous amount of time criticizing all GUI designs, bascially calling them all bad. He uses words like 'stupid', 'idiocy', 'dunderhead', 'idiots' and other colorful metaphors. He spends 80% of the text complaining a criticizing, but falls short of offering constructive criticism or recommended alternatives. The book read like a long venting of his personal views. This is not what I was looking for, and I'm going to toss it.
