Heh. Old SF that brings home that often what is imagined can be limited by what is. It's not possible to write SF that will stand the test of time in this respect unless you're very vague. You can extrapolate on anything but still get most of it wrong and completely miss other things. But this alone wasn't much of a problem - one can enjoy the story telling and description and chuckle at the anachronisms. At the beginning, however, I nearly gave up because of the naive pig-headed behaviour of Barch, the hero. Later on the portrayal of the aliens - basically rubber head humans we've seen in so much SF TV - also irritated. But now I'm remembering that Vance often wrote annoying characters and as a youth it was all the other stuff that kept me uncritically engaged. Still, this rocked along at a good pace and I did extract enjoyment from it.
