Stop the bots
I found the opening scene to the 1991 movie sequel, Terminator 2, to be one of the most powerful SciFi film openings ever. There's a massive firestorm, chunky metal warriors waging war against humans, and then the camera zooms into a metal robot foot crushing a human skull. It’s very graphic. The world has been taken over by terminator robots, first created by man and now bent on destroying us. It's Skynet. What interested me most about this SciFi classic was how real and plausible this future could be, understanding the dark side of human nature that creates evil and some people's inherent need to cause harm.
