In Wretched Writing: A Compendium of Crimes Against the English Language (Perigee, 2013), compiled by Ross Petras and Kathryn Petras, I encountered the following remarkable passage showing the overuse of adjectives. It’s by Pel Torro, aka Lionel Fanthorpe, from his 1968 story Galaxy 666:
The things were odd, weird, grotesque. There was something horribly uncustomary and unwonted about them. They were completely unfamiliar. Their appearance was outlandish and extraordinary. Here was something quite phenomenal about them. They were supernormal; they were unparalleled; they were unexampled. The shape of the aliens was singular in every sense. They were curious, odd, queer, peculiar and fantastic, and yet when every adjective had been used on them, when every preternatural epithet had been applied to their aberrant and freakish appearance, when everything that could be said about such eccentric, exceptional, anomalous creatures had been said, they still remained indescribable in any concrete terms.
Rather than “wretched”, I would say it’s deliberately over the top, done for humorous effect. Extravagant repetition aside, the style is solid and rhetorically varied. But you can see why it’s been singled out.
