Is it ever possible to explain why you suddenly crave something? Popcorn, chocolate, a hamburger, or in my case, one of the early 80s John Carpenter-Kurt Russell flicks. Last weekend it was Escape from New York, this weekend, The Thing. I should have reversed the two since tonight is the night I'm spending by myself, but I solved the problem by renting an even scarier movie-Shattered Glass. That's pretty much the ultimate horror show for a non-fiction writer.
Back to sci-fi for a minute. The specific sci-fi/horror genre of The Thing, Alien, and the remake of Invasion of the Body Snatchers always have a handy computer or tool that projects humanity's doom. It's always a lot of fun to watch the evolution of technology in scary movies, especially when they're not the main show.
