After he pushed the envelope of computer-generated special effects in "The Abyss", director James Cameron turned this hotly anticipated sequel to "Terminator" into a well-written, action-packed showcase for advanced special effects and for one of the most invincible villains ever imagined. "Terminator 2: Judgment Day" is a legitimate sequel: there's more story to tell about a hulking, leather-clad android (Schwarzenegger) who arrives from the future to protect a rebellious teenager and future leader (Edward Furlong) from being killed by the tenacious T-1000 robot (Robert Patrick), whose liquid-metal construction makes him seemingly unstoppable. The fate of the future lies in the balance, with Linda Hamilton reprising her role as the rugged woman whose son will change the course of history.
