The Terminator is stronger and perhaps smarter, and is remorseless about eliminating anyone in his path toward Sarah. Gripping action sequences ensue as Sarah is pursued by the Terminator, with the survival of the human race at stake.
How I felt about it. The Terminator was the film that launched director James Cameron's career. Before that, his only feature was Piranha Part Two: The Spawning, about which no more needs be said. The Terminator was also vital to Schwarzenegger's career, allowing him to escape from Conan-style vehicles into more redeeming fare. Nonetheless, between Cameron and Schwarzenegger, they appear to have made only one film that grades above 60 by my scale, namely, Aliens. Clearly, it is considered more important to make an exciting movie than to make a particularly good one.
For example, one scene has a tanker truck bearing down on Sarah Connor. The tanker trunk is presumably doing 90 miles per hour. Sarah is perhaps running 20 miles per hour. The truck should flatten her within a few seconds. Yet the truck never seems to draw any closer. Dramatic, yes, but at the same time, bogus. The same rule applies to another scene with the Terminator in a motorcycle, following Sarah and Kyle in a car. The cycle can go faster, but never seems to gain any ground. The Terminator would of course close in before firing away, and neither Kyle nor Sarah would stand a chance.
Sarah should get pasted ten times over by the movie's end. Her character might as well be named James Bond, perhaps filmdom's only less likely survivor. It should also said that the Terminator would be more effective if it had built-in weapons, such as laser beams shot from the mouth, that would preclude needing to carry around those pesky, obtrusive machine guns.
How others will see it. Few if any first-time viewers will ponder whether the action scenes are bogus. They want to know two things: is it cool, and is it exciting? Unsurprisingly, the user ratings at imdb.com, while very high, decline with advancing age. Males under 18 give it a 9.0 out of 10, women over 45 award it 6.6 out of 10. Presumably, the latter demographic isn't as enthused over seeing a building full of hapless police officers get wiped out, video game style.
