Oh heck, I’m not going to say much about this – Spielberg does it again. Aliens turned up a million years ago and buried giant killing robots underground. We missed them and built cities over them. They sit in space and watch us for years then zap pilots down into the robots so they can mince humans and make us into fertilizer.
SPOILER ALERT: If the aliens have been watching us for ages, why didn’t they watch the 1953 original and remember to wear encounter suits, lest they succumb to the same ‘flu as the others? Silly aliens.
