GUILTY as charged! Read, and/or have, a lot of the "classics" (Dune series and Asimov, Harry Harrison, Niven, Pournelle and E.E. Smith et al.) Read all the Hitchhiker trilogy (All 5 parts) Currently quite taken with Jay Posey, Jay Allan and Jack Campbell and a few other more modern writers.
I tend to favour the "Space Opera" type material but not 100% exclusively.
I am definitely a Dwarfer and quite like Star Trek (Not so much the newer stuff, although the original themed movies were acceptable), and Star Wars (Original 3!) I am also a fan of Babylon 5 and Battlestar.
Not a fan of Stargate, although the boss, who isn't a Scifi fan REALLY likes it and Blakes' 7.
I am struggling to think of any recent films which I like though. The "Blockbusters" tend to be too over the top and more "shoot-em-ups" than anything else. That got boring YEARS ago.
I hear they are making a "Foundation" Series TV show, which sound intriguing and looks promising if the pre released details are anything to go by.
