With the exception of DH Lawrence and Ray Bradbury I am no story reader. I think I have the complete collection of roughly 40 novels by PKD, and some readers with stories by him, but while I have read many of his novels not just once but twice, three times, I have read most stories not even once.
I like thick novels.
I would love to see Brian Aldiss' Helliconia trilogy being turned into a major film event. To me Helliconia is one of the greatest world panoramas ever described in Science Fiction. Truly monumental.
David Zindell's Neverness would make a nice mini-series, I think, 4 or 6 60-90 minute episodes.
