Query: Sci-fi annulled fantasy in Antrax

Ironically, what a way to destroy the generations of fantasy realms created in the world of Shannara. Although Terry Brooks writing talent is as compelling as ever, Brooks' emphasis on too much science fiction, like the introduction of artificial intelligence, supercomputers, laser-wielding robots and so on in "Antrax", has nulled my hopes that what Brooks is trying to bring to us in the Voyage of the Jerle Shannara trilogy is any fantastic fantasy concepts or elements. Shannara series is engrained in my mind as pure realms of fantasy and because of what Brooks did with "Antrax," my sentimental attachment to the Shannara realms has been shattered and turned upside down. With "Antrax", Brooks has destroyed that pure fantasy world of Shannara which I had loved so dearly. Needless to say, I won't be looking forward to the third installment "Morgawr." If I want to read science fiction, I'm sure I can find a host of other books to choose from.
