I will say here though that I don't think much of the novel. Sorry, but I'll be brutally honest here.
Obviously, since I love the movie, I like the story. But I didn't enjoy the book because the writing style just didn't work for me. Some of it I'm not sure how to explain, but know I didn't like it when Vukovich was repeatedly called "the Pole" (since he's Polish) and Traxler was referred to more than once as "the black man." While I don't object to the characters being called these things occasionally, Hutson used the terms often enough that I started to think that his vocabulary needed to be expanded. Beyond that, I can't really put a finger on why I dislike the writing style. Ok, maybe I could name one or two little things, but I don't want to go there right now.
Also, what's up with Kyle acting a bit out of character in chapter 24? Sarah wants to destroy Cyberdyne Systems to prevent the war, and Kyle (very understandably) isn't enthusiastic about the idea. Sarah gets ticked off and runs off, Kyle catches up to her, and while they're struggling he pulls a gun on her without thinking.
Um...no. I'm pretty sure that drawing on her isn't in his character, especially since Kyle was sent back to protect Sarah.
Despite my complaints, I did enjoy finding out some back story that isn't in the movies. I'm curious to see how much the back story matches up with the other novels when I get hold of them.
This also makes me want to re-watch the movie. :)
