T1 was ahead of its time, T2 just had really good special effects for its time.
What irks me about T2 and later is they fucked up the story line. In T2 they tell us humans didn't develope the terminator technology until they got their hands on the remains of the first terminator from T1. The tech developer in T2 even said "that technology sent us in directions we had NEVER thought of before". Well if that's the case... how the hell did the first one ever get invented in the same time frame, so it could be sent back in time to be defeated and reverse engineered by humans? The dumb writers could have written around that a million different ways, but they didn't. Pretty sad mistake for a movie series that is based on the nuances of time travel and technology.
Salvation looks bad ***. Two main cncerns. Lately all the movies with tons of special effects in them end up just looking like cartoons to me. When you see a spaceship scene and you know its just an animation drawn on a computer, it takes on more the feel of a video game than a movie. I actually prefer stop-animation and animation using models than I do a computer graphics intensive movie. *shrug*
Second concern is the time frame of Salvation. 2018? really? Come on, that's just way too soon for such a technological and societal change as we'd expect from such a paradigm shift in human developement. But then, Hollywood has always done that. Go back and look at movies from the 60's and 70's and they told us by the futuristic year 2000 we'd all be under government control, flying around in our spaceships and shooting laser ray guns at alien robots on Mars. Hollywood always tries to set these types of movies in the 'not so distant' future to try and make the story more easy to relate to (oooo that could happen in my lifetime) and the logisitics tend to get ignored. Im anal on that kinda stuff, to me the details can make or break a movie. With that said, the terminator series have still been a shining example of top-notch sci-fi movies from our generation.
Im personally glad none of the old actors are in it. Same with Star Trek. Im tired of gay remake movies that try to squeeze in as many cameos from the old show as possible. I prefer a movie that's serious about its current story, actors and story line. Leave Shatner in the Priceline commercials where he belongs.
