The “Terminator” franchise, like some kind of robotic killing machine, will just not die. What began as a wonderful one-off in 1984 has blossomed into a franchise that fans and filmmakers keep returning to, with varying degrees of success, one that incorporates spin-offs, sequels, television series and theme park attractions. This year sees another new installment, “Terminator: Dark Fate,” which will be produced by James Cameron and sees the return of Arnold SchwarzeneggerandLinda Hamilton, together for the first time since 1991. Obviously, we are very excited. And we thought we’d look back on the entire franchise. Come with us if you want to live.
