Broad definition, yes, but it's just a broad definition of some of my favorite things. It's not really a genre, no, I just love things set in the future (near or distant) where we haven't fixed everything. Star Trek = blah, Firefly = win. The universe is still semi-corrupt, smugglers and pirates can make a living, and spaceships don't have food synthesizers and waste recyclers, just toilets that come out of your cabin wall and bland protein supplements.
V for Vendetta, Snow Crash, and The Stand seem to be topping my 'to get' list now.
Dark City was a great read, is the movie worth watching?
And does anyone want to port Half Life to the mac, hmmm? Pretty please?
