It hasn't been used yet, so I'll throw in the classic Theodore Sturgeon response to the contention that most science fiction is crap. This version, from 1958, is a bit more developed than some others. Usually people only quote the first part.
"The Revelation
Ninety percent of everything is crud.
Corollary 1
The existence of immense quantities of trash in science fiction is admitted and it is regrettable; but it is no more unnatural than the existence of trash anywhere.
Corollary 2
The best science fiction is as good as the best fiction in any field."
Apparently, Rudyard Kipling and George Orwell had similar revelations.
Kipling: "Four-fifths of everybody's work must be bad. But the remnant is worth the trouble for its own sake."
Orwell: "In much more than nine cases out of ten the only objectively truthful criticism would be "This book is worthless ..."
