Query: Oh, what a waste of time!

I love world-end books...but as far as I can see, Mr. Koontz is not the one capable of writing a world-end story. The book tries to be a unique mixture of world-end books and movies but falls flat on full face. And the ending, with strong echoes of Left Behind series and the Stand, is one of the cheapset ends I have read in my whole life. Skip this stinking trick and re-read the Stand or watch the War of the Worlds again. And Mr Koontz, you'd better stick with your infinite horde of golden retrievers, labradors or whatsoever and your psychopaths--at least you were capable of bringing a REAL END to those stories...A shame on publishing world!
