Rare case where the movie is better than the book
In this case much better.
It's usually the movie where they change the book with some 'happy ending' but in this case it was the book that used some silly deux-ex machina to have the main character, not only survive, but even get married.
Totally destroyed everything in the book that had preceded it. The movie, in contrast, stayed completely true to its message.
I just saw the movie again yesterday and there are a few things about it that make no sense to me but I'll leave them until later.
If anybody else ended the film thinking "this part didn't make sense" is there any reason to believe that some things in the film were supposed to not make sense.
Well just one example of this: why did the Parallax Corporation make the people they killed look like accidental deaths, but have the Senators they were hired to kill assassinated in public?
Given that they went to all the trouble of killing all those people who merely witnessed the death of the first Senator, even though they didn't even know that they had seen something beyond what they thought they had seen, why didn't they, for instance, just give PEP to the Senators they were hired to kill?
I have a few other similar questions like that.
