If PKD was any sort of stylist he would be hugely regarded. He had all these great ideas but one of the crudest prose styles imaginable. And he was terrible at naming characters (Rick Deckard, Roy Batty)!
In SF circles PKD is hugely regarded. He’s the first SF guy in the Library of America, got an award named after him, and he’s the most filmed guy in the genre (though most of the movies made from his stuff are crap). He might not be regarded at all by the literati, but none of the rest of SF is either. Which might explain why SF fans have such low regard for the literati, they hated us first.
