Edward Furlong, who played John Connor in Terminator 2: Judgment Day, had an interesting response to Terminator: Dark Fate’s opening sequence – and it shows how difficult it will be for Terminator 7 to revive the franchise. Several actors have played John Connor in different stages of his life across all Terminator movies, but the T2 version of the character is arguably the most iconic. Judgment Day is widely recognized as the best Terminator movie for multiple reasons, including the relationship between John and a reformed T-800 who was willing to learn from his human friend.
