Terminator's Best Villain Accidentally Created The Franchise's Biggest Plot Hole

Terminator 2: Judgment Day is considered the best film in the Terminator franchise, pitting Arnold Schwarzenegger's T-800 against the ruthless T-1000 (Robert Patrick), whose sleek liquid metal form acts as the perfect foil to the Terminator's muscle-bound frame. However, in addition to bringing Schwarzenegger back as a good guy, T2 is also responsible for introducing one of the biggest plot holes in the series, which contradicts the rules of time travel established throughout the Terminator franchise.
