It always amazes me what some readers find hard to read. Some of the authors mentioned are favorites of mine. At the same time, my least favorite authors, I know to be favorites aroud here, namely Philip K. Dick, Roger Zelazny and Harlan Ellison. It is indeed a situation of what is one person's trash is another's gold. I really don't like (in general) the whole "let's get metaphysical and obtuse" phase of SF in the late 70's and early 80's. But, this was a major phase of SF and I do respect it for what it was.
Have no fear, Gregg Bradley, we are not here to trash authors. We do not tolerate indescriminate author bashing here. But, no author can reach out to all readers. We all have our likes and dislikes.
