I admit I am a bit of a sci-fi geek, and my tastes in books, movies, etc. tend to follow suit.
So here's some of my favorites:
Authors - right now, I really dig Neil Gaiman and Preston & Child. I also like Dan Simmons and Michael Crichton.
Movies - I really dug Equilibrium! Thought it was pure genius and a shame so few people saw it. I like the Hellboy and Matrix movies, too. Guillermo del Toro is an amazing director - he really knows how to create atmosphere. I'm eagerly awaiting The Hobbit.
TV - Warehouse 13 and Eureka are my favorites. Really miss Stargate: Atlantis - not too sure about the latest in the series, Universe. Firefly was a great series while it lasted, too.
Once in a while I read graphic novels. I've read Watchmen, Hellboy, and Those Left Behind.
That's about it!
Guess I need to get back to editing now...
