Terminator 2: Judgement Day
written by James Cameron
Sarah: Watching John with the machine, it was suddenly so clear. Of all the would-be fathers who came and went over the years, this thing, this machine, was the only one who measured up. The Terminator would never stop. It would never leave him. It would never hurt him. It would never shout at him or get drunk and hit him. Or say it was too busy to spend time with him. And it would die to protect him. In an insane world, it was the sanest choice.
