Query: A clone of Die Hard

This novel is purely visual. Absolutely nothing is going on in background or in the character's heads. In fact, there are no characters - with their simplistic reasoning, feelings and motivations, all of these people could've been robots. It would make a great script for a so-so action flick, a clone of all 3 Die Hard movies sans Bruce Willis' presence and occasional comic relief.Science fiction? What science fiction? Only if you thought Hackers or The Net were sci-fi. All technological aspects here amount to some Unix terminology, with several intentional blunders to simplify the concepts. Robotics plays only a secondary role in the plot, an embellishment that does not change the genre of the novel.The only positive thing I can say about this book is that it reads very fast. I did not waste too much time.
