It's a film about a time when computers are in charge but ultimately fail against people fighting back, and they dispatch a Terminator to eliminate the mother of the resistance’s leader before he’s born; simultaneously, someone is sent from that era to protect her. This thriller from James Cameron, who was just starting out, remains thrilling now as it was upon its release. Arnold Schwarzenegger's first performance in what became an unforgettable and arguably unsurpassed character showcases terrific action sequences, shootouts, pursuits, and a complex plot—all unfolding at such a rapid speed that you won’t want to look away. -- DrNostromo.com
