Jonesing A Catastrophe

I don't know why, but I'm really in the mood to read some dark science fiction. Barring that, I'd like to watch a movie that will really, really chill me on a deep human level. The only movies that have ever truly done that to me are Akira (sort of), the final sequence of Beneath the Planet of the Apes, and more notably The End of Evangelion. For some reason I'm just plain in the mood.
