The entire franchise is premised on the notion that sentient killing machines from the future can be sent back in time to take out key human figures destined to lead the resistance against the self-aware AI network known as Skynet, thereby preventing a nuclear holocaust that wipes out the human race. In the original Terminator film, the target was a young and innocent Sarah Connor, future mother to resistance leader John Connor. Then came Terminator 2: Judgement Day, or as I like to call it, The Best Damn Sequel of All Time. A second Terminator is sent to take out a teenaged John—with the twist that Schwarzenegger’s original Terminator has been reprogrammed as his protector against a newer model known as the T-1000.
