Phil Dick is certainly a
Phil Dick is certainly a common thread here, without doubt one of my favourite authors as well. Unfortunately the filming of his work is somewhat hit and miss, Bladerunner good, Minority Report bad, I think the best of the rest might be A Scanner Darkly, whilst not heavily SF themed it is very typical of PKDs work.
As regards the rest, I have been to one convention the Babylon 5 Alliance Gathering in Blackpool, I had an absolute riot. I do read quite a bit of SF, it comes in so many different kinds of flavours that I can read what are seemingly disparate but are still SF. My fave author at the moment is Peter F Hamilton, a UK writer and the current master of the technical space opera. Other authors I like include Norman Spinrad, John Sladek (author of TikTok, the funniest SF novel since Bill The Galactic Hero) and Eric Frank Russell, another top SF humorist.
