Yeah I don't know, I've never particularily liked any of his short stories, but I read them randomly and haven't read that many so I probably just haven't read the good ones. I think what's cool about his take on things is that he focuses on the sort of people that would be side characters at best in anything else (look at how JF Sebastian's role changes from the novel to the film for instance).
I love it though, all the calls to the ex wives, the pathetic jobs, Pris in her many incarnations, the visions of future humiliations, aspirations to doomed relationships, I can read that stuff without the mind fuckery and have a good time. Like when, can't think of their names now, but the girl in A Scanner tells the main character she can't love him because he's too ugly, it's so obviously a thing that someone would say that - and someone must have said to Dick or a friend that it kinda cuts through the whole world book. Like you understand her and him so much better instantly - was kinda disappointed they cut that from the movie. That and the racism thats in the book - which is another thing I think he writes well about.
